The VALUE COLLECTION 64669 is a 5/16 inch hex head lag screw designed for structural fastening applications where corrosion resistance is a priority. Manufactured from Grade 18-8 stainless steel with an uncoated finish, this lag screw measures 1-1/2 inches in length under the head. The hex drive head allows for installation with a standard socket wrench or impact driver, providing consistent torque transfer without cam-out. This fastener is sold in a package quantity of 50 units, making it suitable for project-quantity purchasing. It is appropriate for use by contractors, electricians, plumbers, HVAC technicians, and general tradespeople who need a reliable, rust-resistant lag screw for securing equipment, brackets, or structural connections.
This lag screw is suited for residential and light commercial applications where stainless steel fasteners are specified to resist moisture, chemicals, or outdoor exposure. Common use cases include mounting HVAC equipment support brackets, securing pipe hangers, attaching electrical panels or junction box supports to wood framing, and general mechanical anchoring to wood substrates. The 5/16 inch diameter provides substantial holding strength for medium-duty fastening tasks. The uncoated 18-8 stainless steel construction makes this screw appropriate for both indoor and outdoor environments where galvanic compatibility with stainless hardware is required.
Designed as a standard 5/16 inch hex head lag screw for use with wood substrates in general construction, mechanical, and equipment-mounting applications requiring stainless steel fasteners.
Lag screws of this diameter typically require a pilot hole to prevent wood splitting and to ensure proper seating depth — consult applicable building codes or fastener manufacturer guidelines for recommended pilot hole sizing. Power down or de-energize any nearby electrical equipment before drilling into structural members adjacent to live wiring. Use a socket wrench or impact driver rated for the fastener drive size. Do not overtorque, as stainless steel fasteners are subject to galling if driven without appropriate lubrication or at excessive speed.
