## Description

Lag Screws are used to fasten wood-to-wood and metal-to-wood, attach objects to wood, and affix items to concrete and masonry when combined with lag expansion shields. They are heavy-duty wood screws that are available in larger sizes both in terms of diameter and length and usually have a hex head to facilitate higher installation torque using a wrench. While lateral strength is lower than a comparable bolt and nut, lag screws are useful when access to one side of the joint is limited, the appearance of a nut is undesirable or through-bolt length is excessive.

• Made of sturdy stainless steel; for use in pre-drilled holes
• Hex head enables higher installation torque using a simple wrench
• 8-pack 5/16 in. x 1-1/4 in. external hex-head lag screws
