Value Collection R63234069 Hex Head Lag Screw 5/16 in

Product Description

The VALUE COLLECTION R63234069 is a 5/16-inch hex head lag screw with a 4-inch length under the head, manufactured from 18-8 stainless steel with an uncoated finish. Lag screws of this type are heavy-duty fasteners used to join structural wood members or to anchor hardware into wood substrates. The hex drive head accepts a standard socket or wrench for high-torque installation. The 18-8 stainless steel construction provides good corrosion resistance in outdoor and damp environments, making this screw appropriate for exterior applications, equipment mounting, and structural assembly work where rust resistance is a requirement.

This lag screw is suitable for residential and commercial construction, HVAC equipment mounting, pool equipment anchoring, and general structural fastening into wood framing or heavy timber. Electricians, HVAC technicians, plumbers, and general contractors commonly use lag screws of this size and length when securing equipment pads, brackets, hangers, or structural supports. The 4-inch length under the head provides adequate penetration depth for typical framing lumber and engineered wood applications.

Key Features

• 5/16-inch diameter with 4-inch length under the head for deep thread engagement
• 18-8 stainless steel construction resists corrosion in wet and outdoor environments
• Hex head design accepts standard sockets and wrenches for high-torque driving

Compatibility

Designed for general-purpose structural fastening into wood substrates. Suitable for use with standard framing lumber, heavy timber, and engineered wood products where a 5/16-inch lag screw with 4-inch penetration depth is specified.

Installation Notes

A licensed carpenter, contractor, or trade professional should install lag screws in accordance with applicable building codes and load specifications. Always drill a proper pilot hole sized to the screw shank and thread diameter before driving to prevent wood splitting and ensure full seating. Use a socket wrench or impact driver with the appropriate hex socket. Do not overdrive — seating the head flush against the fastened material is the target without crushing the wood fiber.
