Hillman Fasteners 812530 Galvanized Carriage Bolt 1/4x6 100 Pack

Product Description

The HILLMAN FASTENERS 812530 is a 1/4-inch x 6-inch galvanized carriage bolt sold in a 100-piece pack. It is designed to fasten a wooden face to either a wood or metal frame in structural and general construction applications. The flat, domed head eliminates the need for a washer by providing a semi-flush bearing surface against the workpiece. The square shoulder directly under the head bites into wood upon installation, locking the bolt in place and removing the need for a driving tool during nut tightening. The galvanized finish delivers rust and corrosion resistance for both interior and exterior use, though some surface chalking is normal with this coating type.

These carriage bolts are suited for residential and light commercial construction, framing, decking, fencing, and general structural fastening tasks where a wood face meets a wood or metal frame member. The 6-inch length accommodates thicker assemblies and multi-layer wood sandwiches. The 100-piece pack quantity supports production framing, deck builds, and other high-volume fastening work where consistent bolt sizing across the job is required. Licensed contractors, carpenters, and general tradespeople will find this pack size practical for site use.

Compatibility

Designed to fasten a wooden face to either a wood or metal frame. Suitable for standard 1/4-inch hardware — nuts, washers, and drilled clearance holes — in typical structural wood assembly applications.

Installation Notes

Installation is performed by carpenters, general contractors, or qualified tradespeople following applicable building codes. Drill a clearance hole sized for 1/4-inch bolts through the wood member before inserting the bolt. Tap the bolt through so the square shoulder seats firmly in the wood before threading and tightening the nut from the opposite side. No driving tool is needed on the bolt head once the shoulder is properly seated.
