Value Collection 3GBL9100800 Hex Lag Screw 5/8in X 8in

Product Description

The VALUE COLLECTION 3GBL9100800 is a hex head lag screw designed for heavy-duty fastening applications in wood and structural assemblies. Measuring 5/8 inches in diameter with an 8-inch length under the head, this fastener is manufactured from AISI 1006 low-carbon steel and finished with a hot dipped galvanized coating for corrosion resistance. It conforms to ASME B18.2.1 dimensional standards, making it a reliable choice for structural and outdoor installations where dimensional consistency and coating durability are required. Licensed tradespeople and contractors routinely specify this size and grade for timber connections, ledger attachments, and heavy wood-frame construction.

This lag screw is suited for residential and commercial construction, deck building, timber framing, and structural wood connections. The 5/8-inch diameter and 8-inch length make it appropriate for attaching ledger boards, heavy brackets, and structural lumber where a large-diameter fastener is required to carry shear and withdrawal loads. Its hot dipped galvanized finish makes it a practical option for exterior and pressure-treated lumber applications where sustained moisture exposure is a factor.

Key Features

• 5/8-inch diameter hex head lag screw for high-load wood fastening
• 8-inch length under head for deep penetration in heavy timber connections
• AISI 1006 low-carbon steel construction for toughness and driveability
• Hot dipped galvanized finish provides corrosion resistance in exterior and treated-lumber environments
• Conforms to ASME B18.2.1 dimensional standards for consistent fit and specification compliance

Compatibility

Designed as a standard hex head lag screw for use in wood structural assemblies where a 5/8-inch diameter fastener meeting ASME B18.2.1 is specified.

Installation Notes

Lag screws of this diameter should be installed by a qualified carpenter, contractor, or tradesperson using a properly rated impact driver or socket wrench. Always pre-drill a pilot hole sized per the applicable lumber species and load table to prevent wood splitting and ensure full thread engagement. Follow IBC or IRC code requirements when using lag screws in structural connections such as ledger-to-rim-joist attachments. Power down any adjacent electrical systems before drilling or driving fasteners near utility lines.
