Value Collection R63231124 Hex Lag Screw 1/2x5 Ss 18-8

Product Description

The VALUE COLLECTION R63231124 is a hex head lag screw designed for heavy-duty fastening applications in wood, timber framing, and structural assemblies. Manufactured from grade 18-8 stainless steel with an uncoated finish, this fastener delivers corrosion resistance suitable for both indoor and outdoor installations. The screw measures 1/2 inch in diameter with a 5-inch length under head, providing substantial holding strength in demanding conditions. This lag screw is appropriate for use by general contractors, carpenters, electricians mounting equipment, and HVAC technicians securing equipment bases or brackets to structural members.

This lag screw is commonly used in residential and light commercial construction for attaching ledger boards, mounting heavy equipment, securing structural hardware, and anchoring brackets to wood framing or timber. The hex head drive style allows installation with a standard socket wrench or impact driver, making it practical for jobsite use. The 18-8 stainless steel construction makes it a suitable choice for applications where moisture exposure or corrosion is a concern, such as exterior installations, mechanical rooms, or coastal environments.

Key Features

• Grade 18-8 stainless steel construction for corrosion resistance in wet or outdoor environments
• Uncoated finish — no plating or coating to interfere with torque or galvanic compatibility assessments
• 1/2 inch diameter provides high shear and withdrawal strength in structural wood applications
• 5-inch length under head suitable for fastening through thick lumber or stacked members
• Hex head drive style compatible with standard 3/4-inch sockets or impact drivers

Compatibility

Designed as a standard hex head lag screw for use in wood and timber fastening applications where a 1/2-inch diameter, 5-inch length under head stainless steel fastener is specified.

Installation Notes

Installation of 1/2-inch lag screws typically requires a pilot hole to prevent wood splitting — pilot hole diameter and depth should follow applicable structural fastener guidelines or manufacturer specifications for the substrate. A socket wrench, ratchet, or impact driver with a 3/4-inch socket is the standard installation tool. For structural applications, refer to the applicable building code, including IBC or IRC load tables, to confirm fastener spacing and embedment depth. Do not overdrive; proper seating is flush to slight countersink at the head bearing surface.
