Description

A Rawl bolt is a heavy-duty metal fastener used to attach objects to concrete, stone, or brick walls, floors, and roofs. They are made up of a steel bolt, expansion brackets, and ferrules. How they work When tightened, the bolt head draws the metal sleeves into the sides of the drilled hole. The sleeves expand and bite into the hole, forming a tight anchor point. The ferrule at the top of the sleeves holds them together, and the steel clip at the bottom holds them together. How to install them Mark the location where you want to install the bolt. Drill a hole that is slightly larger than the bolt. Insert the bolt and tighten it until it covers the internal threads. Tap the bolt with a hammer to insert it properly.
