Value Collection 6256LG Hex Head Lag Screw 5/8 in Steel

Product Description

The VALUE COLLECTION 6256LG is a hex head lag screw designed for heavy-duty fastening applications in wood, structural framing, and mechanical mounting tasks. Measuring 5/8 inches in diameter with a 3.5 inches length under the head, this fastener is manufactured from AISI 1006-1022 carbon steel with a hot-dipped galvanized finish that provides corrosion resistance in outdoor and exposed environments. The hex head drive allows installation with standard wrenches or impact drivers. It meets ASME B18.2.1 dimensional standards, making it a code-compliant choice for structural and mechanical trade work.

This lag screw is suited for residential and commercial construction, HVAC equipment mounting, electrical panel and equipment anchorage, plumbing support bracketing, and general structural fastening into wood substrates. The hot-dipped galvanized finish makes it appropriate for exterior installations, pressure-treated lumber contact, and areas with moisture exposure. Tradespeople across HVAC, plumbing, electrical, and general construction trades will find this fastener applicable across a wide range of field and shop tasks.

Key Features

• 5/8 inches diameter with 3.5 inches length under head for deep bite in structural wood
• Hot-dipped galvanized finish for corrosion resistance in exterior and moisture-prone environments
• Hex head design compatible with standard wrenches and impact drivers
• Meets ASME B18.2.1 dimensional standards for consistent fitment and code compliance
• AISI 1006-1022 carbon steel construction for reliable shear and tensile strength

Compatibility

Designed as a standard hex head lag screw for use in wood-to-wood and hardware-to-wood fastening applications where a 5/8 inches diameter fastener conforming to ASME B18.2.1 is specified.

Installation Notes

Lag screws of this diameter typically require a pilot hole to prevent wood splitting and to ease installation torque. A licensed contractor, journeyman electrician, plumber, or HVAC mechanic may install this fastener as part of equipment anchoring or structural support work in accordance with applicable local building codes. Always consult relevant codes such as the IBC or NEC when using fasteners for structural or equipment-mounting purposes. Do not overtighten, as stripping the wood substrate or fastener head can compromise holding strength.
