Hillman 3/8 in x 4 in.External Hex Hex-Head Lag Screws (3-Pack)

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.

• Hex head is easily driven with simple wrenches and requires minimal clearance above the fastener
• Common applications include retaining walls, deck frames, and outdoor play equipment
• Stainless steel material
• Use in pre-drilled hole
