Stainless Steel Thin Head Open-End Knurled Rivet Nuts

JUXIN FASTENERS manufactures stainless steel thin head open-end knurled round body blind rivet nuts for creating reusable internal threads in thin sheet metal, hollow sections, and OEM assemblies requiring one-sided installation.

The low-profile flange reduces head projection, while the external knurling helps resist insert rotation in compatible round mounting holes. The open-end design allows screw extension where sufficient backside clearance is available.

Product Specification

Stainless Steel Thin Head Open-End Knurled Rivet Nuts – Technical Specifications

JUXIN FASTENERS supplies stainless steel thin head open-end knurled blind rivet nuts for industrial OEM manufacturers, sheet-metal fabricators, equipment designers, and procurement teams requiring reusable threaded attachment points in thin materials.

These low-profile ribbed rivet nuts combine a reduced-height flange with an externally knurled cylindrical body. They can be installed from one accessible side using a compatible rivet nut setting tool.

Engineering Features and Selection Considerations

Low-Profile Head for Limited Clearance

The thin flange reduces surface projection compared with conventional flat-head rivet nuts.

This makes the design useful for closely fitted equipment covers, mounting brackets, electrical panels, and compact sheet-metal assemblies.

A thin head does not automatically provide a completely flush installation.

Where flushness is critical, engineers should evaluate flange thickness, mating-part clearance, and any required recess geometry.

Knurled Body for Rotational Engagement

The external knurling helps resist insert rotation by engaging the surrounding material during installation.

Actual spin-out resistance depends on mounting-hole diameter, parent-material properties, grip thickness, installation stroke, and the geometry of the selected rivet nut.

For applications involving elevated tightening torque, compare the required torque with validated insert performance rather than relying on knurling alone.

Open-End Configuration for Screw Clearance

The open threaded end allows a mating screw or bolt to extend beyond the rivet nut body where backside clearance is available.

Engineers should verify screw length, thread engagement, and clearance to adjacent components before approving the assembly.

Stainless Steel Material Selection

Stainless steel may provide corrosion-resistance advantages for selected industrial environments. However, material grade and service conditions must be considered together.

Where corrosion exposure, dissimilar-metal contact, or material traceability is critical, specify the required stainless steel grade and supporting documentation in the RFQ.

Installation in Thin Sheet Materials

Blind rivet nuts create mechanically retained internal threads where direct tapping may provide insufficient thread engagement or where rear access is unavailable.

The workpiece must fall within the selected part's grip range. Correct hole preparation and setting-tool adjustment are essential to installation consistency.

Industrial Applications

Automotive and Transportation: Mounting brackets, interior equipment panels, fabricated housings, and serviceable sheet-metal components.

Electrical and Electronics: Control cabinets, instrument housings, electronic enclosures, and equipment mounting panels.

Industrial Machinery: Protective covers, access panels, light-gauge structural components, and maintenance assemblies.

HVAC and Appliances: Sheet-metal cabinets, mounting brackets, removable covers, and fabricated equipment housings.

OEM Sheet-Metal Fabrication: Reusable threaded connections in hollow sections and components requiring blind-side installation.

Engineering and Procurement RFQ Requirements

For efficient technical evaluation and quotation, please provide:
