Mini Rivet Bushing Standoff Technical Datasheet
Product Overview
Mini Rivet Bushing Standoffs are compact, permanently installed threaded inserts with an integrated spacer designed to provide both a reusable internal thread and a fixed stand-off distance in thin sheet metal assemblies. They eliminate the need for separate spacers or standoffs, reducing component count and simplifying assembly.
Installed by mechanically peening the projecting shank after insertion, Mini Rivet Bushing Standoffs form a permanent mechanical joint while the serrated flange embeds into the sheet material to provide excellent resistance to rotation. Their compact design makes them ideal for applications with limited installation space where components such as PCBs, electrical assemblies, covers, or brackets require a precise mounting distance from the sheet.
Manufactured in zinc-plated steel and stainless steel, Mini Rivet Bushing Standoffs are widely used in electrical enclosures, electronics, telecommunications, industrial automation, instrumentation, medical equipment, and precision sheet metal fabrication.

Installation
- Select the correct rivet bushing length based on the sheet thickness. Refer to the dimensional table to determine the recommended hole diameter, then punch or drill the hole to the specified size.
- Insert the rivet bushing into the prepared hole, ensuring the spigot passes completely through the sheet. The flange must sit flush against the sheet surface and the bushing must be aligned perpendicular to the material to ensure accurate thread positioning after installation.
- Using a profiled installation punch, apply sufficient pressure to peen the protruding spigot over the sheet. This forms a secure mechanical lock while allowing the serrations beneath the flange to embed into the sheet material, providing excellent resistance to rotation and ensuring a permanent installation.

Frequently Asked Questions
What is a Mini Rivet Bushing Standoff?
A Mini Rivet Bushing Standoff is a permanent threaded insert with an integrated spacer that provides both a reusable internal thread and a fixed stand-off distance in thin sheet metal.
Why use a Mini Rivet Bushing Standoff instead of a separate spacer?
It combines two components into one, reducing assembly time, inventory, and the risk of misplaced or loose spacers while ensuring a consistent stand-off height.
What materials are available?
Mini Rivet Bushing Standoffs are commonly available in zinc-plated steel and stainless steel.
Can they be installed in aluminium sheets?
Yes. They are suitable for installation in aluminium, mild steel, and stainless steel sheets when the correct hole size and installation tooling are used.
Are the threads reusable?
Yes. The internal threads are designed for repeated assembly and disassembly without compromising the integrity of the installation.
What industries commonly use Mini Rivet Bushing Standoffs?
They are widely used in electronics, telecommunications, industrial automation, electrical enclosures, medical equipment, and sheet metal fabrication where components require a fixed mounting distance.
