Hillman Fasteners 230137 Hex Lag Bolt 1/2x5 in Zinc 25pk

Product Description

The HILLMAN FASTENERS 230137 is a zinc-finished hex head lag bolt sized at 1/2 inch diameter by 5 inches in length, sold in a 25-pack. Lag bolts of this type are heavy-duty wood fasteners driven with a wrench or socket rather than a screwdriver, making them suitable for structural and load-bearing connections. The hex head design allows for high torque application with standard hand or power tools. The zinc finish provides a basic level of corrosion resistance for general-purpose use. This fastener is commonly installed by carpenters, general contractors, HVAC technicians securing equipment pads, electricians mounting strut or structural members, and plumbers anchoring pipe supports.

This lag bolt is appropriate for a wide range of residential and light commercial applications, including wood-to-wood structural connections, ledger board attachment, beam and joist hardware, equipment mounting to wood substrates, and general framing tasks. The 1/2 inch diameter and 5 inch length make it well suited for applications requiring a deep, secure bite into dimensional lumber or engineered wood members. It is packaged in a 25-count box, convenient for single-job use or replenishing a fastener kit.

Key Features

• 1/2 inch diameter by 5 inch length — suited for structural wood connections
• Hex head design accepts standard sockets and wrenches for high-torque driving
• Zinc finish provides basic corrosion resistance for interior and sheltered exterior use
• 25-pack quantity supports single-job or small-project needs
• Heavy-duty lag thread pattern for strong wood-to-wood or hardware-to-wood grip

Compatibility

Designed as a general-purpose hex head lag bolt for use in wood framing, structural lumber, and equipment mounting applications where a 1/2 inch diameter by 5 inch fastener is specified.

Installation Notes

Lag bolts of this size typically require a pilot hole to prevent wood splitting — consult applicable building codes or structural drawings for correct pilot hole diameter. Drive using a socket wrench or impact driver with the appropriate socket size. For structural applications, installation must comply with local building codes and, where applicable, IBC or IRC fastener schedule requirements. Do not use in applications where full outdoor exposure or chemical environments require a higher corrosion-resistance rating than zinc plating provides.
