Hexsert

A hexsert is a rivet nut with a hexagonal body that is set into a hole to provide a threaded fixing point in thin sheet. It allows a bolt or machine screw to be used where the sheet is too thin to tap.

A hexsert sets a threaded hole in thin sheet, so a machine screw or bolt can fasten a part to the sheet. It takes a setting tool that pulls the insert and upsets the body against the rear face. A low profile hexsert sits close to the surface, while a large flange hexsert spreads load over a wider area.

This kind of insert is usually made from steel, stainless steel or aluminium. Steel gives high strength. Stainless steel resists corrosion.

This is a general guide to checking this kind of part. It says nothing about any supplier's parts.

Ask for a certificate of conformance and a mill test certificate if the material is critical. On receipt, check the thread runs freely and the body is not distorted. Confirm the thread size and material match the order.
