Masonry bolts (concrete bolts or anchor bolts) are strong variety fasteners which are made to attach things to concrete solid surfaces. Each type of anchor is designed to fit specific materials, for instance, loose bolts are suitable for solid masonry but are inappropriate for hollow brick walls. Masonry bolts are made from a broad spectrum of materials, ranging from stainless steel as well as zinc plated to galvanised steel and have finishes to allow high work loads with varying applications.
