Collet Anchor

A collet anchor is a type of fastener in the form of a small metal sleeve. One end has slits that ensure a secure connection during installation. The inside is threaded, into which a screw is driven.

Most often such anchors are made of brass — a strong and ductile material. Sometimes steel fasteners are used when a heavy structure needs to be secured. The most common sizes are a diameter of 6-20 millimeters and a length of 25-80 millimeters.

How to use

First, a hole needs to be drilled for the anchor. It is then driven in with a hammer, which is why it is also called a “drive-in” anchor. A bolt or screw is used for the final fastening. As it is tightened, the anchor’s segments spread apart and press firmly against the wall.
