Product details
Description
Upgrade your hardware assembly projects with this bulk pack of 100 fully threaded carriage bolts, manufactured to strict ASME B18.5 standards. Designed for reliable wood-to-wood and wood-to-metal applications, these fasteners feature a distinct shallow domed head and a square neck underneath that securely bites into material holes to prevent unwanted spinning during tightening.
Crafted from low-carbon steel with a protective zinc plating, they offer reliable durability and basic corrosion resistance for indoor or sheltered outdoor installations. Whether you are building furniture, securing decks, or working on general construction, these coarse thread bolts provide a secure, self-locking mechanism that can be easily installed using a single wrench from one side.
How to use
- Drill a pre-bored hole matching the bolt diameter through the materials to be fastened.
- Insert the carriage bolt so that the square neck seats firmly into the material.
- Attach the compatible nut and washers on the threaded end, and tighten securely using a wrench.
