With different materials, thread designs, locking functions, and surface treatments available, our custom nuts manufacturer solutions help customers meet specific application requirements.

Classification of Nuts by Function and Design

According to different functions and application requirements, industrial nuts can be classified into several categories, including standard nuts, locking nuts, adjustment nuts, and special-purpose nuts.

1. Standard Nuts

Standard nuts are the most commonly used fastening components for general mechanical assembly.

They are designed to work together with bolts, screws, and threaded studs to create reliable mechanical connections.

Common standard nut types include:

• Hex nuts

• Flange nuts

• Square nuts

• Weld nuts

• T nuts

• Cap nuts

Standard nuts are widely used in machinery manufacturing, automotive assembly, industrial equipment, and general engineering applications.

For OEM production, selecting the correct thread specification, material grade, and surface treatment ensures stable assembly performance.

2. Locking Nuts and Anti-Loosening Solutions

In applications involving vibration, impact, or continuous movement, standard nuts may gradually loosen during operation.

Locking nuts are designed to prevent loosening and maintain stable fastening performance.

Common anti-loosening nut solutions include:

• Nylon insert lock nuts

• All-metal self-locking nuts

• Prevailing torque nuts

• Serrated flange lock nuts

These self-locking nuts are widely used in:

• Automotive components

• Railway equipment

• Industrial machinery

• Agricultural equipment

• Heavy-duty mechanical systems

For high-vibration environments, selecting the correct locking nut design is important to improve equipment reliability and reduce maintenance costs.

3. Thread Adjustment Nuts

Thread adjustment nuts allow engineers to modify positioning, spacing, or preload during assembly.

These nuts are commonly used where precise mechanical adjustment is required.

Typical applications include:

• Precision machinery

• Automation equipment

• Optical devices

• Mechanical positioning systems

Thread adjustment solutions help manufacturers achieve accurate positioning and improve assembly flexibility.

Classification of Nuts by Material

Material selection directly affects corrosion resistance, mechanical strength, electrical performance, and application reliability.

Carbon Steel Nuts

Carbon steel nuts are widely used because of their excellent strength, cost efficiency, and availability.

Typical applications:

• Industrial machinery

• Construction equipment

• General mechanical assembly

Different surface treatments such as zinc plating, black oxide, and zinc-nickel coating can improve corrosion resistance.

Stainless Steel Nuts

Stainless steel nuts provide excellent corrosion resistance and durability.

Common stainless steel grades include:

• Stainless Steel 304

• Stainless Steel 316

They are widely used in:

• Food processing equipment

• Medical equipment

• Marine applications

• Outdoor structures

• Chemical equipment

For harsh environments requiring long-term corrosion protection, stainless steel fastening solutions are often the preferred choice.

Copper Nuts

Copper nuts offer excellent electrical conductivity and corrosion resistance.

They are commonly used in:

• Electrical equipment

• Electronic devices

• Power systems

• Grounding applications

Copper nuts provide reliable electrical connection performance where conductivity is required.

Aerospace and High-Reliability Applications

Aerospace applications demand extremely high standards for safety, weight reduction, and reliability.

Special nut fasteners are used in:

• Aircraft assembly

• Aircraft maintenance

• Satellite equipment

• Aerospace structures

Materials such as stainless steel, aluminum, titanium, and high-performance alloys can be selected according to application requirements.

How to Select the Right Nut Fasteners?

Choosing the correct nut requires consideration of several key factors:

1. Material Requirements

Select materials according to the working environment:

• Carbon steel → General industrial applications

• Stainless steel → Corrosive or outdoor environments

• Copper → Electrical applications

• Aluminum and titanium → Lightweight applications

2. Thread Compatibility

Proper thread matching between bolts and nuts is essential.

Incorrect thread selection may cause:

• Thread damage

• Insufficient clamping force

• Fastening failure

Engineers should confirm:

• Thread size

• Thread pitch

• Thread tolerance

• Standard requirements

3. Operating Environment

Consider:

• Vibration level

• Temperature conditions

• Corrosion exposure

• Mechanical load

For high-vibration applications, locking nuts or self-locking nuts are recommended.

4. Surface Treatment Selection

Different coatings provide different levels of protection:

• Zinc plating

• Zinc-nickel plating

• Black oxide

• Nickel plating

• Dacromet / Geomet coating

The correct surface treatment improves corrosion resistance and extends product service life.
