Hillman Fasteners 230095 Hex Lag Bolt 3/8x4 in Zinc 50-pack

Product Description

The HILLMAN FASTENERS 230095 is a zinc-plated hex head lag bolt supplied in a 50-piece pack. Each bolt measures 3/8 inch in diameter by 4 inches in length and is driven with a standard hex wrench or socket. Lag bolts of this type are heavy-duty wood fasteners used to secure structural members, ledger boards, hardware, and equipment to wood substrates. The zinc plating provides basic corrosion resistance suitable for interior and sheltered exterior applications. This pack is a practical stocking quantity for contractors and service techs who need reliable fasteners on the job.

These lag bolts are used across residential and light commercial construction, HVAC equipment mounting, electrical panel and conduit support, plumbing hanger installations, and general structural fastening to wood framing. A box quantity of 50 pieces suits repetitive tasks such as deck ledger attachment, equipment pad anchoring, or joist hanger supplemental fastening where multiple bolts are required per installation.

Key Features

• 3/8 inch diameter by 4 inch length for deep bite into wood framing members
• Hex head drive accepts standard sockets and impact wrenches for fast installation
• Zinc plating for corrosion resistance in sheltered and interior environments
• 50-piece pack quantity reduces reorder frequency on multi-fastener jobs
• Heavy-duty lag design handles structural load requirements in typical framing applications

Compatibility

Designed as a general-purpose hex head lag bolt for use in wood framing, structural lumber, and equipment mounting applications where a 3/8 inch by 4 inch fastener is specified.

Installation Notes

A licensed contractor or qualified tradesperson should install lag bolts in structural applications per applicable building codes. Always drill a proper pilot hole sized to the shank and thread diameter before driving to prevent wood splitting and ensure full seating. Use a socket wrench or impact driver set to an appropriate torque to avoid stripping the hex head or over-driving into the substrate. For exterior or wet-area structural use, verify that zinc plating meets the corrosion-resistance requirements of the applicable code or engineer specification.
