Product Information

Full details

The TIMco 0865CB Carriage Bolt and Hex Nut set is designed for builders, carpenters, and DIY enthusiasts who need a reliable, anti-spin fastening solution for timber projects. These M8 x 65mm bolts excel at securing ironmongery or heavy timber structures with a clean, low-profile finish, though they are specifically intended for wood-to-wood or wood-to-metal connections and should not be used in high-stress overhead lifting applications.

Extended Product Information

FAQs

Can these be used outdoors?

Yes, they are BZP (Bright Zinc Plated) and suitable for outdoor use, though they may eventually show signs of surface rust if exposed directly to harsh, wet weather.

What is the head diameter of this bolt?

The head diameter for this M8 bolt is 20.00mm.

Do I need to buy nuts separately?

No, the TIMco 0865CB pack includes 50 bolts and 50 corresponding hex nuts.

Is this bolt fully threaded?

These bolts are fully threaded up to 150mm; since these are 65mm in length, they are fully threaded.

Can I use these for hanging heavy swings or climbing frames?

These are grade 4.8 carbon steel and are not rated for high-stress or safety-critical overhead lifting. Consult a structural engineer for critical load-bearing applications.

Troubleshooting

Bolt spins in the hole when tightening the nut

Ensure the square shoulder is fully seated into the timber by tapping the head with a hammer.

Bolt head is not sitting flush

Check that the hole is not obstructed and that the square shoulder has enough room to penetrate the wood surface.

Nut is difficult to thread

Inspect the bolt threads for debris or damage; ensure the nut is not cross-threaded during initial application.

Pros and Cons

Pros

  • Square shoulder design prevents the bolt from spinning during tightening
  • Domed head provides a flush and clean aesthetic finish
  • Zinc plating helps resist corrosion in standard environments
  • Complete set including hex nuts saves on additional purchases

Cons

  • Not suitable for high-stress or critical load-bearing applications
  • Grade 4.8 steel is softer than high-tensile hardware
  • Requires a pilot hole to be drilled correctly for the square shoulder to seat

Setup, Compatibility & Care

  1. Preparation: Always drill a hole the same diameter as the bolt (8mm) through your timber.
  2. Installation: Insert the bolt and tap the head with a hammer until the square shoulder is fully embedded in the wood surface.
  3. Tightening: Thread the included hex nut onto the bolt and tighten with a suitable wrench or spanner until secure.
  4. Care: While the zinc finish is durable, avoid using these in highly acidic or marine environments, as salt and moisture can accelerate oxidation. Keep bolts in their original packaging to avoid thread damage or moisture buildup before use.
