Why this carriage bolt stands out
Designed for wood-to-wood connections, these carriage bolts provide a solid, reliable hold where a smooth, rounded head is preferred for aesthetics and safety. The 7/16 in diameter and 2-1/2 in length strike a balance between strength and practicality for a variety of projects, from framing and decking to furniture and shelving supports. The coarse thread helps with secure engagement in typical softwoods and many hardwoods, making them a versatile choice for both DIY enthusiasts and professional builders.
Ideal applications
- Decking and railing frames where a clean, finished look is desired
- Furniture assembly and repair, including frames and supports
- Shelving systems, brackets, and light structural work
- Fencing, garden structures, and outdoor sheds
- General carpentry projects that require a durable, corrosion-resistant fastener
Practical installation tips
- Pre-drill holes sized to accommodate the bolt diameter to prevent wood splitting.
- Insert the bolt through the upper piece and thread a nut on the opposite side to secure. Use a washer if the load distribution requires it.
- Avoid overtightening to prevent damage to the wood—tighten until the joint feels firm, then stop.
- Store in a dry, organized box (the boxed packaging helps keep the 50 bolts together for ongoing projects).
For reliable, everyday fastening that combines solid metal with practical corrosion resistance, Hillman’s 7/16 in. x 2-1/2 in. zinc-plated steel carriage bolts are a smart choice. They’re built to perform with wood-centric projects and deliver peace of mind across multiple applications.
