Value Collection R63231488 Hex Lag Screw Stainless 18-8

Product Description

The VALUE COLLECTION R63231488 is a 1/2-inch hex head lag screw with a 3-1/2-inch length under head, manufactured from 18-8 stainless steel with an uncoated finish. Lag screws of this type are heavy-duty fasteners designed to anchor structural members, equipment mounting brackets, and heavy fixtures to wood substrates. The hex drive head accepts a standard wrench or impact driver socket, and the coarse lag thread profile provides strong pull-out resistance in dimensional lumber and engineered wood. The 18-8 stainless steel construction resists corrosion in wet, outdoor, and coastal environments where carbon steel fasteners would fail prematurely.

This lag screw is suited for structural and general construction applications including deck framing, ledger board attachment, equipment pad anchoring, fence post hardware, and mechanical equipment mounting. Tradespeople in HVAC, plumbing, electrical, and pool service routinely use lag screws of this specification to secure equipment stands, conduit supports, and structural brackets to wood-framed structures. The 1/2-inch diameter and 3-1/2-inch length under head make this an appropriate choice for connections requiring substantial shear and withdrawal load capacity in medium-to-heavy framing members.

Key Features

• 18-8 stainless steel construction for corrosion resistance in outdoor and high-moisture environments
• Hex head drive accepts standard 3/4-inch wrench or impact driver socket
• 1/2-inch nominal diameter with coarse lag thread for high pull-out strength in wood
• 3-1/2-inch length under head suitable for medium-depth structural connections
• Uncoated finish maintains dimensional tolerances and allows inspection of base material

Compatibility

Designed as a standard 1/2-inch hex head lag screw for use in wood structural connections, equipment mounting, and general construction fastening applications where stainless steel corrosion resistance is required.

Installation Notes

A pilot hole should be drilled prior to installation to prevent wood splitting and reduce drive torque; pilot hole diameter is typically determined by the species and density of the lumber being fastened. Drive with an appropriately sized socket wrench or impact driver set to a controlled torque to avoid stripping the hex head or over-compressing the substrate. Always consult applicable building codes and structural fastener schedules for load-bearing connections. Wear appropriate eye protection when drilling pilot holes and driving large-diameter fasteners.
