Anchor bolts are used to attach structures and fixtures to masonry. Light posts, bridge railings and hand rails are examples of items requiring anchor bolts to attach them securely to concrete slabs or floors. In addition, walls and stairs are permanently fastened to concrete slabs and other walls during construction, using various sizes of anchor bolts. Most anchor bolts are a minimum of 1/2-inch in diameter in order to provide adequate tensile strength.
J-hook and L-hook Bolts
J-hook and L-hook anchor bolts have a bend at one end to grab onto the concrete or masonry structure. These type of anchor bolts are normally cast-in-place---meaning they are inserted into the concrete as soon as it is poured. The concrete cures, and securing retains the bolts in place.
