Hillman Hex Bolt - Steel - 1/2-13 x 2-1/2 In.

Hex Lag Screws are used for directly fastening into wood surfaces. They are used with a lag shield, and lag screws can be used in masonry applications. The hex head is six-sided and ideal for easy driving and quick installation. The threads on lag screws are designed to embed into the wood, rather than relying on a nut to secure the connection.

Hex Bolts are bolts with hexagonal heads and machine threads for use with a nut or in a tapped hole. As the most common type of bolt, Hex Bolts are standard hex bolts with a washer face under the head. Usually Hex Bolts are only partially threaded.
