The Timco Carriage Bolts and Hex Nuts (M12 x 200mm) are engineered for professional contractors and DIY enthusiasts who need a reliable, heavy-duty fastening solution for timber projects. Featuring a domed head with a square anti-spin shoulder, these bolts provide excellent structural integrity when securing ironmongery or joining heavy wooden beams. While they offer superior clamping force and rust resistance due to the BZP finish, the 200mm length is substantial and may require pre-drilling for precise alignment in thinner applications.

No. These bolts are partially threaded to provide better structural support for heavy timber applications.
No, each bolt comes supplied with a compatible hex nut.
The BZP finish is suitable for sheltered outdoor use, but for highly corrosive environments, stainless steel may be required.
This model features a 12mm metric diameter.
No, these are specifically designed for clamping and fastening timber.
Ensure the square shoulder is fully tapped into the timber. If the wood is too hard, use a hammer to seat the shoulder firmly before tightening the nut.
Check that the pilot hole is deep enough and free of debris. Use a slightly larger drill bit if the timber is exceptionally dense.
To install these bolts effectively, use a drill bit slightly larger than 12mm to create a pilot hole. Gently tap the bolt head into the wood until the square shoulder is fully recessed, which prevents it from spinning. Once the bolt is seated, thread the included hex nut onto the end and tighten with a wrench or socket set.
For ongoing care, keep these bolts in a dry environment until use to maintain the Bright Zinc Plated finish. If used in exterior garden projects, consider applying a silicone-based sealant around the bolt head to further prevent moisture ingress into the timber.
