Value Collection 36BL9100300 Hex Lag Screw 5/8in Steel

Product Description

The VALUE COLLECTION 36BL9100300 is a hex head lag screw designed for heavy-duty fastening applications in wood, timber framing, and structural assemblies. Manufactured from AISI 1006-1022 grade steel with a hot dipped galvanized finish, this screw delivers corrosion resistance suited to outdoor and exposed environments. The 5/8-inch nominal diameter and 3-inch length under head provide strong clamping force in applications where standard wood screws are insufficient. It conforms to ASME B18.2.1 dimensional standards, ensuring consistent fitment with standard hex drive tooling. Installers in construction, HVAC mounting, and plumbing support work will recognize this as a standard structural fastener.

This lag screw is used in residential and light commercial construction for attaching ledger boards, mounting structural brackets, securing equipment supports, and fastening heavy timber connections. The hex head design accepts a standard socket wrench or impact driver, making it practical for field installation. The hot dipped galvanized coating makes it appropriate for pressure-treated lumber contact and exterior applications where moisture exposure is expected.

Key Features

• 5/8-inch diameter with 3-inch length under head for deep structural engagement
• Hot dipped galvanized finish for corrosion resistance in outdoor and treated-lumber applications
• Hex head drive accepts standard socket or impact driver tooling
• Meets ASME B18.2.1 dimensional standards for consistent sizing
• AISI grade 1006-1022 low-carbon steel construction

Compatibility

Designed as a standard hex head lag screw for use in wood and timber fastening applications requiring a 5/8-inch diameter fastener conforming to ASME B18.2.1.

Installation Notes

Lag screws of this diameter typically require a pilot hole drilled to the appropriate shank and thread diameter before driving to prevent wood splitting and ensure full seating. A standard hex socket or impact wrench is used to drive the fastener. Follow applicable building codes, including IRC and IBC provisions, for structural fastener requirements. Always verify fastener compatibility with the base material and finish when working with pressure-treated lumber.
