Value Collection HXLI20501800G-025BX Hex Head Lag Screw

Product Description

The VALUE COLLECTION HXLI20501800G-025BX is a heavy-duty hex head lag screw designed for structural fastening applications in wood, timber framing, and heavy construction assemblies. Measuring 1/2 inch in diameter with an 18-inch length under head, this fastener provides exceptional holding power in deep or thick material stacks. Constructed from Grade 2 steel with a hot-dipped galvanized finish, it resists corrosion in exterior and high-moisture environments. Licensed tradespeople and construction crews rely on this size lag screw for ledger board attachments, post-to-beam connections, and heavy structural tie-ins.

This lag screw is suited for residential and commercial construction projects where long fastener penetration is required. Typical applications include deck framing, heavy timber joinery, pergola assembly, and structural retrofits. The 1/2-inch shank diameter and 18-inch length make it a go-to fastener when standard-length screws cannot achieve the required embedment depth. It is well suited for treated lumber applications where a galvanized coating is required to prevent accelerated corrosion from preservative chemicals.

Key Features

• Hot-dipped galvanized finish provides corrosion resistance for exterior and pressure-treated lumber use
• Grade 2 steel construction meets general-purpose structural fastener standards
• 1/2-inch diameter shank delivers high shear and withdrawal load capacity
• 18-inch length under head allows deep embedment in thick timber or layered assemblies
• Hex head drive style compatible with standard impact wrenches and socket sets

Compatibility

Designed as a general-purpose hex head lag screw for use in wood-to-wood and wood-to-steel structural fastening applications where a 1/2-inch diameter, 18-inch galvanized fastener is specified.

Installation Notes

Installation is typically performed by carpenters, structural contractors, or licensed building tradespeople. Always pre-drill a lead hole sized to the shank and thread diameter to prevent splitting, especially in hardwoods or near board edges. Drive with an impact wrench or breaker bar and appropriate hex socket. Consult applicable building codes, including IRC and IBC fastener schedules, for required embedment depths and spacing when used in structural connections.
