Machine Screw Anchor

Material: Zamac alloy cone with lead sleeve



Description:

The machine screw anchor is an expansion anchor specifically designed for quick and secure fastening in hard materials such as brick, concrete, or stone.

Its design consists of a zinc alloy cone and a lead alloy sleeve. During installation, a tool is used to drive the cone into the sleeve, causing it to expand and anchor firmly within the hole. The screw is then used to fasten the attached object securely in place.This mechanism also gives it the name “calk in anchor.”
