The VALUE COLLECTION HXLI20310550G-050BX is a hex head lag screw designed for heavy-duty wood fastening applications in trade and construction work. Measuring 5/16 inches in diameter with a 5.5-inch length under the head, this screw is manufactured from Grade 2 steel with a hot-dipped galvanized finish for corrosion resistance in outdoor and high-moisture environments. It is sold in a minimum quantity of 50 pieces per order. Installers driving this fastener into structural lumber, decking, ledger boards, or equipment mounting applications will find the hex head drive well suited to socket or wrench installation.
This lag screw is commonly used in residential and commercial construction and trade service work. Typical applications include securing deck ledger boards to framing, mounting HVAC equipment supports, attaching structural brackets, fastening wood to wood assemblies, and anchoring equipment pads or racking systems. The hot-dipped galvanized coating makes it appropriate for exterior installations and pressure-treated lumber, where bare steel fasteners would corrode prematurely. Plumbers, HVAC technicians, electricians, and general contractors routinely specify galvanized lag screws for equipment mounting and structural attachment work.
Designed as a general-purpose hex head lag screw suitable for structural wood fastening, equipment mounting, and exterior construction applications requiring a 5/16-inch corrosion-resistant fastener.
Lag screws of this type are installed by general contractors, carpenters, and trade technicians using a socket wrench or impact driver with the appropriate hex bit. A pilot hole should be drilled prior to installation to prevent wood splitting and to achieve proper seating depth. When fastening into pressure-treated lumber, verify that the galvanized coating grade meets current code requirements for the specific treatment chemical in use. Follow applicable building codes and manufacturer structural tables for load ratings and fastener spacing.
