Value Collection HXLI203105500-100BX Hex Lag Screw 5/16 in

Product Description

The VALUE COLLECTION HXLI203105500-100BX is a 5/16-inch hex head lag screw designed for heavy-duty fastening applications in wood and structural assemblies. With a 5-1/2-inch length under the head, this lag screw provides substantial thread engagement for secure, load-bearing connections. Constructed from Grade 2 steel with a zinc plating finish, it delivers corrosion resistance suitable for general-purpose indoor and sheltered outdoor installations. The hex drive head accepts a standard wrench or socket for installation. This box contains 100 screws, making it a practical supply quantity for contractors and tradespeople working on larger projects.

This lag screw is used in residential and light commercial construction and mechanical trade work, including wood framing, structural connections, deck building, equipment mounting, and HVAC equipment anchoring. Electricians, HVAC technicians, and general contractors routinely use lag screws of this size to secure equipment to wood framing, blocking, or structural members. The 5-1/2-inch length under head accommodates thicker material stacks and provides reliable pull-out resistance in dimensional lumber.

Installation Notes

Lag screws should be installed by qualified tradespeople following applicable building codes and fastener manufacturer guidelines. Always drill a properly sized pilot hole in the receiving material before driving the lag screw to prevent wood splitting and ensure full seating. Use a socket wrench or impact driver set to an appropriate torque to avoid stripping the hex head or over-driving into the substrate. Follow local building codes, including IBC or IRC requirements, when using lag screws in structural or load-bearing connections.
