Description
A 5/16-inch x 1-inch Zinc Carriage Bolt is a simple, dependable fastener for projects that need a clean, finished look and solid clamping strength. Timberline Fasteners’ steel, zinc-plated carriage bolts resist corrosion while providing a silver finish that blends into outdoor and indoor applications. Grade 2, coarse threads deliver reliable engagement for wood and light-gauge metal work. Use these bolts for securing deck boards, attaching gate hardware and hinges, fastening fence pickets, assembling outdoor furniture or building playground and garden structures where a smooth, domed head is desired. The 1-inch length suits many common thicknesses without protruding excessively, making these bolts a practical choice for homeowners, carpenters and DIYers tackling repair or new-build tasks.
