The TIMco Carriage Bolt and Hex Nut is a heavy-duty fastening solution specifically engineered for timber clamping and securing ironmongery to wood structures. Ideal for both DIY enthusiasts and professional carpenters, these carbon steel bolts offer exceptional stability thanks to their square anti-spin shoulder design, though they are best suited for indoor or dry environments due to their limited corrosion resistance.

No. These bolts have a corrosion rating of 1, meaning they are intended only for clean, dry, and low-humidity indoor environments.
You will need a 17mm socket or wrench to tighten the provided hex nut.
No. They are fully threaded up to 150mm, with partial threading for the remainder of the 280mm length.
They are manufactured from high-strength carbon steel with a Bright Zinc Plated (BZP) finish.
Each box contains 10 carriage bolts and 10 corresponding hex nuts.
The square shoulder is not properly seated. Use a hammer to tap the head of the bolt firmly into the wood so the square neck locks into the timber fibers.
Ensure your drill bit size matches the 10mm bolt diameter. If the hole is too tight, clear away wood debris inside the bore.
To install, first drill a pilot hole through your timber using a 10mm bit. Insert the carriage bolt and use a hammer to seat the square shoulder firmly into the wood. Tighten the included hex nut using a 17mm socket wrench or spanner until the connection is secure. Avoid over-tightening, which can crush the timber fibers.
Maintenance is simple: keep the bolts dry. Because the finish is rated for low-humidity environments, avoid using them in areas exposed to direct rain, chemicals, or salt air, as these conditions will accelerate oxidation. If the zinc coating is scratched during installation, applying a light coat of rust-inhibitor spray can help maintain the bolt's longevity in borderline environments.
