L anchor bolts, also known as foundation bolts, are headless fasteners with a partially threaded shank. The top un-threaded portion is bent at a 90° right angle, which produces the "L" shape of the bolt. These anchor bolts are used to connect structural and non-structural components to concrete. Made from AISI 1008 carbon steel. Available in hot dip galvanized finish, which provides a corrosion resistant zinc coating.
