Product Information

Full details

The TIMco M10 x 100mm Carriage Bolt is designed for professional builders, landscapers, and DIY enthusiasts who require a reliable, rust-resistant solution for securing timber structures or mounting heavy-duty ironmongery. Its primary benefit is the A2-grade stainless steel construction, which provides exceptional longevity in harsh or wet environments, though users should note that nuts are sold separately and must be purchased to complete the installation.

Extended Product Information

FAQs

Are nuts included with these bolts?

No, nuts are not included with the TIMco Carriage Bolts.

Can I use these bolts with Green Oak?

Yes, A2 stainless steel is specifically recommended for Green Oak due to the wood's inherent acidic characteristics.

What tools are needed for installation?

You will need a drill with an M10 bit, a non-marking mallet for seating the head, and a wrench or socket set for the nut.

Are these bolts fully threaded?

The product is fully threaded up to and including 150mm; since this is a 100mm bolt, it is fully threaded.

Can these be used in saltwater environments?

A2 stainless steel is highly resistant to corrosion but is not recommended for direct saltwater or marine environments; A4 (316) stainless steel would be required for those conditions.

Troubleshooting

Bolt rotates while tightening

Ensure the square shoulder is fully seated into the timber by tapping the head with a mallet; if the wood is too hard, slightly countersink the square hole.

Surface discoloration (tea staining)

Clean the surface with a stainless steel cleaner and ensure no carbon steel tools or abrasive brushes were used during installation.

Pros and Cons

Pros

  • Superior corrosion resistance due to A2 stainless steel
  • Self-locking square shoulder prevents rotation during installation
  • Suitable for high-tannin timber like Green Oak
  • Clean, professional aesthetic for exposed structures

Cons

  • Nuts not included in the package
  • Not suitable for marine environments with high chloride levels
  • Higher initial cost compared to zinc-plated alternatives

Setup, Compatibility & Care

For proper installation, drill a pilot hole matching the M10 diameter. Insert the bolt through the timber and tap the dome head gently with a non-marking mallet to seat the square shoulder. Use a corresponding M10 nut and washer to secure the assembly. Since these are A2 stainless steel, avoid using carbon steel tools to tighten the nuts, as microscopic iron particles left on the bolt surface can cause 'tea staining' or surface rust. Keep threads clean and free of debris during installation to prevent seizing.
