  • Lag Screws

Hex Lag Screws, also called Lag screws, are used in wood construction. The threads on lag srews 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”.
