The VALUE COLLECTION HXLI203705500-025B is a 3/8-inch hex head lag screw with a 5-1/2-inch length under head. Constructed from Grade 2 steel with a zinc-plated finish, this fastener is built for structural wood connections and heavy-duty anchoring tasks. The hex head design accepts a standard wrench or socket drive, allowing controlled torque during installation. The zinc plating provides corrosion resistance suitable for general indoor and protected outdoor applications. This screw is a standard trade-supply fastener stocked for contractors, carpenters, and general construction professionals.
Hex head lag screws of this size are commonly used in wood framing, ledger board attachments, deck construction, and structural timber connections. The 3/8-inch diameter and 5-1/2-inch length under head make this fastener well suited for connecting dimensional lumber where a through-bolt is not practical. It is widely used in residential and light commercial construction, as well as HVAC equipment mounting, equipment pad anchoring, and general mechanical room fastening applications.
Designed as a general-purpose 3/8-inch hex head lag screw suitable for structural wood connections in residential and light commercial construction applications.
Installation is typically performed by carpenters, general contractors, or mechanical trades securing equipment to wood substrates. Pre-drilling a pilot hole sized to the root diameter of the screw is strongly recommended to prevent wood splitting and ensure proper seating. Use a hex socket or open-end wrench rated for the fastener size. Always follow applicable building codes and structural fastener requirements for the specific application.
