Overview

The slotted body of this rivet nut splits open as it is set, gripping a large area on the blind side. It suits plastics, wood, fibreglass and other soft or brittle materials, and covers a very wide grip range.

How it works

A rivet nut gives a strong, reusable thread in sheet metal, tube or plastic that is too thin to tap, and it is fitted from one side only. Here is how this nut goes in.

1 Make the holeDrill or punch a round hole tothe size in the table. Noaccess to the back is needed.2 Insert the nutPush the nut in until the headsits on the sheet.3 Set itThe tool pulls the thread up:the thin wall behind the sheetfolds into a tight collar andclamps.4 FastenScrew in the bolt to fix thepart. The thread can be usedagain and again.
Installation in four steps (simplified illustration).

Slotted body

Slots in the body open into wide legs behind the panel. The large footprint spreads the load, so it holds in soft or brittle material such as plastic, GRP and plywood.

Choosing the grip

Each part number sets in a range of sheet thickness (the grip). Pick the part whose grip covers your sheet: too thin and the collar will not clamp, too thick and the nut cannot fold. The hole size is in the table.

Open end

The thread runs right through, so a longer bolt can pass through the nut.

Head

Flat head: a wide head that spreads the load and covers the hole edge.

Setting tools

Set with a hand, pneumatic-hydraulic or battery tool fitted with the matching mandrel. See our riveting tools.
