Value Collection HXLI20621600G Hex Lag Screw 5/8x16 in

Product Description

The VALUE COLLECTION HXLI20621600G is a heavy-duty hex head lag screw built for structural and industrial fastening applications. It measures 5/8 inches in diameter with a 16-inch length under the head, giving it the reach needed for thick timber connections, ledger board attachments, and heavy structural assemblies. Constructed from Grade 2 steel with a hot-dipped galvanized finish, this lag screw resists corrosion in exterior and treated-lumber environments. The hex drive head accepts standard socket wrenches or impact drivers, making installation fast and reliable on the job site.

This lag screw is suited for residential and light commercial construction, timber framing, deck ledger attachments, pergola and carport framing, and other heavy wood-to-wood or wood-to-structural connections. The hot-dipped galvanized coating meets common requirements for use with pressure-treated lumber, where standard zinc-plated fasteners are not appropriate. It is typically installed by carpenters, general contractors, and structural trades working on exterior or exposed framing applications.

Key Features

• 5/8-inch diameter with 16-inch length under head for deep structural penetration
• Hot-dipped galvanized finish provides corrosion resistance suitable for exterior and pressure-treated lumber applications
• Grade 2 steel construction delivers reliable strength for heavy timber and structural fastening
• Hex head design accepts standard hex sockets and impact drivers for fast installation
• Coarse wood-screw thread pattern bites into timber without pre-splitting

Compatibility

Designed as a standard hex head lag screw for use in heavy wood structural connections where a 5/8-inch diameter, 16-inch fastener is specified.

Installation Notes

Lag screws of this diameter typically require a pilot hole to prevent splitting; consult applicable building codes for pilot hole sizing requirements. Use a hex socket or impact driver rated for the fastener size. When installing into or adjacent to pressure-treated lumber, confirm that the galvanized coating grade meets local code requirements for the treatment chemical used. Follow all applicable structural fastening provisions in the current International Building Code or project engineering specifications.
