Value Collection R63234440 Hex Head Lag Screw 5/16 in

Product Description

The VALUE COLLECTION R63234440 is a 5/16-inch hex head lag screw with a 1-1/2-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 into wood substrates, providing strong, load-bearing connections in structural and mechanical applications. The hex drive head accepts a standard socket or wrench for installation. The 18-8 stainless steel alloy provides corrosion resistance in both indoor and outdoor environments, making this screw a reliable choice for trade professionals working in wet, coastal, or chemically exposed conditions.

This lag screw is suited for residential and light commercial applications where a durable threaded wood fastener is required. Typical uses include securing lumber framing, attaching brackets and hardware to wood structural members, and fastening equipment supports or housings to wood backing. HVAC, plumbing, and electrical trades commonly use lag screws of this size to mount equipment, conduit supports, pipe hangers, and strut channels to wood framing or blocking. The 5/16-inch diameter and 1-1/2-inch length under head are appropriate for medium-duty anchoring tasks in dimensional lumber.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet and outdoor environments
• Hex head drive accepts standard sockets and wrenches for consistent torque application
• Uncoated finish maintains dimensional accuracy and avoids coating interference in tight clearances
• 5/16-inch diameter provides solid load-bearing capacity in wood substrates
• 1-1/2-inch length under head suits medium-depth anchoring into dimensional lumber

Compatibility

Designed as a standard 5/16-inch hex head lag screw for use in wood fastening applications across HVAC, plumbing, electrical, and general construction trades.

Installation Notes

Installation is performed with a socket wrench or hex driver sized for the hex head. A pilot hole is strongly recommended in hardwood substrates to prevent splitting and reduce drive torque. Power down or de-energize any equipment in the work area before driving fasteners into structural members near electrical or mechanical systems. Follow applicable building codes for fastener spacing and load requirements when used in structural connections.
