Hexagon Rivet Bushes

Hexagon Rivet Bushes

(3 products)

Hexagon rivet bushes feature a serrated shank that clinches into sheet metal, giving thin panels a strong threaded socket that won't spin out. Choose Self Colour Steel Bushes for welding or BZP Hex Bushes for clean electronics enclosures.

Hexagon rivet bushes (often referred to as hex serrated bushes or press nuts) are designed to provide strong, permanent internal threads in thin sheet metal fabrications where tapping a thread directly into the material isn't possible. The hexagonal body profile prevents the insert from spinning under high torsional load, while the undercut serrated spigot deforms and clinches securely into the walls of a pre-punched or drilled hexagonal hole. Once installed flush, they create a robust, high-torque anchor point capable of accepting standard metric bolts without stripping or loosening during repeated assembly and disassembly.

Selecting the correct material finish depends on your application and corrosion requirements. For general enclosure manufacturing and indoor electronic chassis, our Bright Zinc Plated (BZP) Hexagon Bushes offer cost-effective protection against surface rust. For welding directly into steel fabrications prior to powder coating or painting, Self Colour Steel Rivet Bushes ensure a clean metal to metal bond. If your assembly will face outdoor weather, chemical exposure, or marine environments, upgrading to A2 Stainless Steel Hexagon Bushes prevents galvanic corrosion and joint degradation. Be sure to select the correct spigot length matching your exact sheet metal gauge to ensure maximum pull-out strength.

Frequently Asked Questions

How does a hexagon rivet bush install into sheet metal?

A hexagon rivet bush is pressed into a pre-punched or laser-cut hexagonal hole in sheet metal. Using a bench press or installation punch, pressure is applied to the serrated spigot, driving the teeth into the parent metal while swaging the shank down to lock the insert permanently in place.

Why choose a hexagon rivet bush over a round rivet bush?

The hexagonal shape provides significantly higher spin-out resistance compared to round profiles. While round bushes rely solely on serrations for grip, the flat sides of a hex bush mechanically lock into the sheet metal, making them ideal for high-torque applications where bolts are repeatedly tightened.

How do I select the right spigot length for my sheet thickness?

Rivet bushes are manufactured with specific spigot lengths designed to match standard sheet metal gauges (such as 1.2mm, 1.6mm, 2.0mm, or 2.5mm). The spigot length should match or be slightly less than the thickness of the sheet so that it flattens and clinches flush without protruding past the reverse side of the panel.
