The Timco Carriage Bolts & Hex Nuts (M12 x 75mm) are essential heavy-duty fasteners designed for DIYers and professionals looking to secure timber projects or attach ironmongery. Featuring a signature domed head and square anti-spin shoulder, these bolts provide a clean, secure finish, though they are specifically limited to timber-based applications where the square neck can seat properly.

The head diameter for the M12 bolt is 30mm.
Yes, these bolts are fully threaded up to 150mm, and since these are 75mm, the threads run the entire length of the bolt.
No, these are specifically designed for timber as the square shoulder requires a soft material to seat properly and prevent rotation.
You will need a drill with a 12mm bit, a spanner or socket wrench for the hex nut, and a hammer or mallet to seat the head.
Each package contains 2 pieces, including the corresponding nuts.
Ensure the square shoulder is properly seated into the timber; tap the head with a hammer to force the square section into the wood.
Check that the hole is drilled to the correct M12 diameter and clear any wood debris or splintering from inside the hole.
For optimal results, ensure the hole is drilled slightly larger than 12mm to allow the bolt shaft to pass through, but be careful not to make it so large that the square shoulder cannot grip the wood. To seat the head properly, use a rubber mallet to gently drive the dome head into the timber surface. While the zinc finish provides good standard corrosion resistance, avoid using these in direct contact with harsh chemicals or in extremely acidic soil conditions. Wipe down the bolts with a dry cloth after installation to remove any metal shavings or debris.
