Product Information

Full details

Designed for builders, carpenters, and DIY enthusiasts, these Timco M6 x 100 carriage bolts are ideal for securing timber structures and attaching ironmongery with a clean, professional finish. The combination of the domed head and square anti-spin shoulder ensures a secure, non-rotating fit, though users should note that the M6 diameter is best suited for light-to-medium structural applications rather than heavy-duty load-bearing joints.

FAQs

What size drill bit should I use for an M6 bolt?

Use a 6mm or 6.5mm drill bit for a clean fit, depending on how tightly you want the bolt to sit in the wood.

Are these bolts suitable for outdoor use?

Yes, but as they feature a standard silver finish, applying a rust-preventative spray or grease is recommended for long-term exposure to the elements.

Does the pack include washers?

No, this pack includes only the carriage bolts and the corresponding hex nuts.

What is the diameter of the head?

The domed head has a diameter of 16.00mm.

Can these be used for metal-to-metal connections?

Carriage bolts are specifically designed for timber because the square shoulder requires a soft material to bite into to prevent rotation.

Troubleshooting

Bolt rotates when tightening the nut

Ensure the square shoulder is properly seated by tapping the head firmly into the wood before beginning to tighten.

Nut is difficult to thread onto the bolt

Check the threads for any debris or wood shavings and ensure the bolt is perfectly perpendicular to the nut.

Pros and Cons

Pros

  • Integrated anti-spin shoulder simplifies one-person installation
  • Smooth domed head prevents injuries and clothing snags
  • Includes matching hex nuts for convenience
  • High-quality steel construction for reliable hold

Cons

  • Limited to a 4-piece pack size
  • Not intended for heavy-duty structural steel connections
  • Silver finish may require additional anti-corrosion coating for harsh outdoor environments

Setup, Compatibility & Care

To ensure a secure hold, always use a washer (not included) between the nut and the wood surface to prevent the nut from crushing the timber fibers during tightening. For installation, a standard 10mm spanner or socket is required to fit the M6 nut. If installing outdoors, it is recommended to apply a small amount of outdoor-rated wood glue or a thin layer of weather-resistant lubricant to the threads to prevent rust and future seizure. Store any unused bolts in a dry environment to maintain the finish and structural integrity.
