Hillman Fasteners 812515 Galvanized Carriage Bolt 100 Pack

Product Description

The HILLMAN FASTENERS 812515 is a galvanized carriage bolt sold in a 100-piece pack, sized at 1/4 inch diameter by 2.5 inches in length. These fasteners are designed to secure a wooden face to either a wood or metal frame. The flat head eliminates the need for a washer while providing a semi-flush finish at the surface. The square underside of the head is self-locking, preventing spinning during installation and removing the need for a driving tool on the bolt itself. The galvanized finish delivers reliable rust prevention, though it may present a chalky appearance in some applications.

These carriage bolts are suited for residential and light commercial construction, woodworking, framing, and general structural fastening where corrosion resistance is required. Common applications include deck construction, fence assembly, outdoor structures, and wood-to-metal connections exposed to moisture. The 100-piece pack quantity supports production work and job-site efficiency for carpenters, general contractors, and trade professionals handling volume fastening tasks.

Installation Notes

Carriage bolts are typically installed by general contractors, carpenters, or maintenance trades. Before installation, drill a correctly sized clearance hole through the workpiece so the square neck seats flush and locks without spinning. A nut and wrench are required on the threaded end to draw the joint tight. No driving tool is needed at the bolt head once the square neck is properly seated in the substrate.
