DIN 660 Steel Round Head Solid Rivets: Joint Design, Installation and OEM Supply

DIN 660 Steel Round Head Solid Rivets: Joint Design, Installation and OEM Supply

DIN 660 steel round head solid rivets are permanent mechanical fasteners used in suitable metal assemblies where a formed rivet head provides a non-removable connection.

Unlike bolts and screws, solid rivets do not rely on a threaded fastening mechanism.

 Installation involves inserting the rivet through aligned holes and plastically deforming the free end to create a closing head.

For industrial OEMs, successful riveting depends on the relationship between rivet geometry, material condition, hole preparation, joint thickness and forming process.

A correctly selected rivet can provide a durable connection. 

However, its performance cannot be assessed from rivet material strength alone.

The connected plates, edge distances, bearing stresses, installation quality and service loads may govern the joint.

This guide focuses specifically on DIN 660 steel round head solid rivets, rather than treating every solid rivet head style and material as equivalent.

For mechanical and structural engineers, the main concerns include load paths, hole geometry, joint deformation and failure prevention.

For manufacturing engineers and production managers, tooling access, rivet feeding, closing-head consistency, inspection and assembly cycle time are equally important.

For procurement and supplier development teams, dimensional conformity, material specification, batch consistency, 

samples and long-term sourcing requirements determine whether an alternative rivet supplier is suitable.

Juxin Fasteners supplies steel solid rivets and drawing-specific industrial fastening components for OEM manufacturing applications.

What Is a DIN 660 Steel Solid Rivet?

A DIN 660 solid rivet is a solid-shank rivet with a round, domed factory head defined by the applicable DIN dimensional specification.

The rivet is installed through prepared holes in the components being joined.

The free end is then formed into a closing head using an appropriate riveting process.

Typical Components of a Solid Rivet

• Preformed factory head

• Solid cylindrical shank

• Free end for closing-head formation

Important Distinction

DIN 660 describes a particular round head rivet geometry.

It should not be used as a universal standard reference for flat head, countersunk or other rivet head styles.

DIN 660 Round Head Geometry

The round head has a domed profile that protrudes above the connected surface.

Its geometry influences:

• Tool contact

• Head support

• Local bearing

• Clearance around the joint

• Appearance

• Installation access

Engineering Consideration

A protruding round head may not be suitable where a flush external surface is required.

DIN 660 Versus Other Solid Rivet Head Styles

Engineering Recommendation

Specify the actual rivet head dimensions and applicable standard.

Do not assume that different head styles are interchangeable.

Steel Materials for DIN 660 Solid Rivets

Steel solid rivets may be produced from materials selected for the required forming behavior and service conditions.

The original product range includes carbon steel and alloy steel options.

However, the suitability of a steel grade depends on its composition, condition and installation method.

Carbon Steel Solid Rivets

Carbon steel may be selected for general industrial riveting applications.

Engineering Considerations

• Formability

• Mechanical properties

• Installation process

• Corrosion exposure

• Material compatibility with the connected parts

Alloy Steel Solid Rivets

Alloy steels may be considered for drawing-specific applications.

Important Limitation

A material with higher nominal strength is not automatically a better riveting material.

If the material is too hard or insufficiently ductile for the intended process, closing-head formation may become difficult or produce defects.

Engineering Recommendation

Select rivet material according to both installed joint requirements and forming capability.

Rivet Diameter Selection

Rivet diameter affects the nominal shank area, hole size, installation force and joint geometry.

For a circular shank, the nominal cross-sectional area is:

A = πd² / 4

Where:

• A = nominal shank cross-sectional area

• d = nominal shank diameter

This geometric relationship is useful for preliminary calculations.

Important Limitation

Nominal shank area alone does not determine the allowable shear load of a riveted joint.

Material properties, shear planes, hole condition, installation quality and connected-member failure modes must also be considered.

Rivet Length and Grip Thickness

The required rivet length depends on the total thickness of the materials being joined and the amount of shank needed to form the closing head.

Grip Thickness

Grip thickness is the total thickness of the components captured between the rivet heads.

Closing-Head Allowance

Additional shank length is required to form the closing head.

The necessary allowance depends on:

• Rivet diameter

• Material

• Closing-head geometry

• Forming method

• Joint configuration

Important Distinction

Rivet length should not be selected solely by adding an arbitrary fixed allowance to grip thickness.

Engineering Recommendation

Validate the required length using the applicable installation specification, tooling requirements and trial assembly.

Hole Diameter and Hole Preparation

Correct hole preparation is essential for reliable riveting.

Hole Diameter

The hole must accommodate rivet insertion while allowing the intended installed joint behavior.

Hole Quality

Relevant factors include:

• Hole diameter

• Roundness

• Alignment

• Burrs

• Surface condition

• Hole spacing

• Plate thickness

Potential Problems

Oversized holes may allow excessive movement or produce an unfavorable installed geometry.

Undersized or misaligned holes may damage the rivet during insertion.

Engineering Recommendation

Specify hole tolerances based on the joint design and riveting process.

Rivet Edge Distance and Pitch

Rivet spacing and distance from the plate edge influence joint strength.

Edge Distance

Insufficient edge distance can increase the risk of tear-out or edge deformation.

Pitch

Rivet pitch affects load distribution and the available net section of the connected plate.

Engineering Considerations

• Plate material

• Plate thickness

• Rivet diameter

• Load direction

• Number of rivets

• Joint geometry

• Manufacturing tolerances

Important Limitation

A universal edge-distance or pitch value should not be applied to every industrial riveted joint.

Engineering Recommendation

Determine these dimensions using the applicable structural or product design requirements.

Single-Shear and Double-Shear Riveted Joints

The number of shear planes affects the load path through a rivet.

Single-Shear Joint

A typical single-shear arrangement has one principal shear plane through the rivet.

Double-Shear Joint

A suitable double-shear arrangement has two principal shear planes.

Important Limitation

A double-shear arrangement should not automatically be assumed to provide exactly twice the usable joint capacity.

Plate bearing, geometry, load distribution and other failure modes may control the design.

Common Riveted Joint Failure Modes

A riveted connection may fail through several mechanisms.

Rivet Shear

The rivet may fail across one or more shear planes.

Plate Bearing

The rivet may deform the surrounding hole or cause excessive bearing deformation.

Plate Tear-Out

Material near an edge may tear under load.

Net-Section Failure

The connected plate may fail through a reduced cross-sectional area containing rivet holes.

Head or Closing-Head Failure

An improperly formed head may fail or allow joint separation.

Fatigue Cracking

Repeated loading may initiate cracks in the rivet or connected members.

Engineering Recommendation

Evaluate the complete joint rather than considering only rivet shear strength.

How DIN 660 Solid Rivets Are Installed

Solid riveting requires access to both sides of the joint, unless a specialized process provides an equivalent forming arrangement.

Typical Installation Sequence

1. Prepare and inspect the component holes.

2. Align the connected parts.

3. Insert the solid rivet.

4. Support the factory head with suitable tooling.

5. Form the free end into the specified closing head.

6. Inspect the completed joint.

Important Consideration

The exact process depends on rivet diameter, material, equipment and joint configuration.

Cold Riveting of Steel Solid Rivets

Cold riveting forms the closing head without intentionally heating the rivet to a hot-working temperature.

Potential Advantages

• No separate heating step

• Compatibility with suitable production equipment

• Reduced thermal exposure of adjacent components

Engineering Considerations

• Rivet material ductility

• Diameter

• Required forming force

• Tooling capacity

• Risk of cracking

• Closing-head consistency

Important Limitation

Not every steel solid rivet can be cold-formed successfully at every diameter or hardness.

Hot Riveting of Steel Solid Rivets

Hot riveting involves heating the rivet before forming the closing head.

It has historical and specialized uses in steel construction and heavy-duty assemblies.

Engineering Considerations

• Heating temperature

• Transfer time

• Material condition

• Forming process

• Cooling behavior

• Worker safety

• Joint specification

Important Limitation

Hot riveting is not simply a substitute for cold riveting.

The material, joint design and installation procedure must be suitable for the selected process.

Cold Riveting Versus Hot Riveting

Engineering Recommendation

Select the installation method before finalizing rivet material, length and tooling.

Closing-Head Formation

The closing head is the deformed end of the installed rivet.

Its geometry influences joint integrity.

Important Characteristics

• Head diameter

• Head height

• Symmetry

• Surface condition

• Contact with the connected component

Common Installation Defects

• Incomplete head formation

• Cracking

• Excessive deformation

• Off-center head

• Damaged factory head

• Misaligned rivet

• Loose joint

Production Recommendation

Establish acceptance criteria for the installed closing head and verify them during process qualification.

Rivet Installation Equipment

• Riveting presses

• Pneumatic riveting equipment

• Impact riveting tools

• Specialized forming equipment

• Application-specific fixtures

Production Considerations

• Forming force

• Tool alignment

• Cycle time

• Head support

• Operator access

• Tool wear

• Part handling

• Inspection

Engineering Recommendation

Validate rivet geometry using the actual production equipment.

Vibration and Fatigue in Riveted Joints

A solid rivet has no threaded locking interface.

However, this does not mean that a riveted joint is immune to fatigue or vibration-related damage.

Potential Risks

• Joint slip

• Fretting

• Hole elongation

• Fatigue cracking

• Local deformation

• Loss of clamping effectiveness

Engineering Recommendation

For cyclic or vibration-sensitive applications, evaluate the complete connection under representative service loads.

Corrosion Protection for Steel Solid Rivets

Steel rivets may require surface protection depending on their environment.

Potential coating systems include:

• Zinc-based coatings

• Black oxide

• Zinc-nickel coatings

• Nickel coatings

• Other drawing-specified protective systems

The suitability of each system depends on the rivet material, forming method and environmental exposure.

Important Limitation

Not every coating is suitable for every rivet geometry or installation process.

Coating Damage During Riveting

Riveting plastically deforms part of the rivet.

This deformation may damage certain coatings.

Potential Effects

• Cracking

• Flaking

• Exposed steel

• Reduced corrosion protection

• Local coating discontinuity

Engineering Recommendation

Evaluate coating performance after installation, not only on the uninstalled rivet.

Pre-Installation Versus Post-Installation Coating

The coating sequence can influence corrosion performance.

Pre-Installation Coating

Potential advantages include coating individual rivets before assembly.

However, forming may damage the coating.

Post-Installation Coating

Coating after riveting may protect the completed assembly, depending on access, process compatibility and environmental requirements.

Engineering Recommendation

Define the coating sequence in the assembly specification.

Hot-Dip Galvanizing Considerations

Hot-dip galvanizing may be suitable for certain steel components.

However, coating thickness, geometry, installation process and joint requirements must be considered.

Important Limitation

Hot-dip galvanizing should not automatically be specified for small precision rivets or rivets requiring substantial deformation after coating.

Galvanic Corrosion in Mixed-Metal Joints

When steel rivets contact dissimilar metals in the presence of an electrolyte, galvanic corrosion may occur.

Relevant Factors

• Metal combination

• Electrolyte exposure

• Surface area relationship

• Coating condition

• Joint geometry

Engineering Recommendation
