Lag Bolts & Hex Lag Screws

Hex Lag Screws, also called Lag bolts, are used in wood construction. The threads on lag bolts are designed to embed into the wood, rather than relying on a nut to secure the connection. Lag screws have a hex head or square head, with spaced threads and a gimlet point. Lag screws are generally used in pre-drilled holes in wood. The pilot hole is typically pre-drilled in the wood before inserting the bolt, and must be sized to allow the threads to embed tightly and securely in the wood. When used with a lag shield, lag screws can be used in masonry applications.

Hex Lag Screws, or Lag Bolts, are available in steel with a zinc or galvanized finish; and in 18-8 stainless.

Sizes range from ¼” to 1” diameter with lengths up to 18”.
