Product Information

Full details

The Timco M12 x 130mm Carriage Bolts are designed for professional contractors and DIY enthusiasts who need a reliable, heavy-duty fastening solution for timber-to-timber or timber-to-ironmongery projects. These bolts feature a domed head with a square anti-spin shoulder that ensures a secure, clean finish, making them ideal for outdoor structures like decking, fencing, or framing. A notable caveat for users is that the necessary nuts are not included with the purchase, requiring you to source M12 nuts separately to complete your assembly.

Extended Product Information

FAQs

Are the nuts included?

No, the nuts are not included. You will need to purchase M12 stainless steel nuts separately.

Are these bolts fully threaded?

These bolts are fully threaded up to 150mm. Since these are 130mm, they are fully threaded.

Can I use these for marine applications?

While A2 stainless steel offers good corrosion resistance, for direct salt spray or marine exposure, A4 (316) stainless steel is typically recommended. A2 is best for standard outdoor weather conditions.

What is the head diameter?

The carriage bolt features a standard dome head design consistent with DIN603 specifications.

Can I use these with Green Oak?

Yes, A2 stainless steel is required for Green Oak as the acidity in the wood will cause standard steel fasteners to corrode rapidly.

Troubleshooting

Bolt spins while tightening

The square shoulder is not fully seated in the timber. Use a hammer to tap the head firmly into the wood until the square profile is embedded.

Timber splits during installation

The pilot hole is likely too small or non-existent. Ensure the pilot hole is at least 12mm in diameter to accommodate the bolt shaft.

Pros and Cons

Pros

  • Superior corrosion resistance compared to zinc-plated alternatives
  • Square shoulder design prevents rotation during installation
  • Durable stainless steel construction suitable for harsh environments
  • Clean, professional-looking domed head finish

Cons

  • Nuts are not included and must be purchased separately
  • Higher initial cost compared to carbon steel fasteners
  • Requires pre-drilling to prevent timber splitting during insertion

Setup, Compatibility & Care

To ensure a successful installation, follow these guidelines:

  1. Pre-Drilling: Always drill a pilot hole slightly larger than 12mm into the timber. This prevents the wood from splitting when the square shoulder is tapped into place.
  2. Securing: Use a mallet to lightly tap the domed head into the timber until the shoulder is fully seated.
  3. Compatibility: These bolts are compatible with any standard metric M12 nut. Ensure you use stainless steel nuts to maintain the anti-corrosion properties of the entire assembly.
  4. Care: Keep the bolts in a dry place before use to prevent contamination from carbon steel tools, which can cause surface discoloration (tea staining) on stainless steel products.
