FAQs

Are nuts included with these bolts?

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

Are these bolts suitable for saltwater environments?

While A2 stainless steel offers high corrosion resistance, for extreme saltwater or marine applications, A4 (316 grade) stainless steel is generally recommended.

What size drill bit should I use?

You should use a 12mm drill bit, or slightly larger depending on the clearance required for your specific application.

Can I use these with Green Oak?

Yes, A2 stainless steel is specifically recommended for materials like Green Oak, which have inherent corrosive characteristics that can degrade lower-quality metals.

What is the length of the bolt?

The bolt is 110mm in length, measured from under the dome head to the end of the threads.

Do these bolts conform to any specific standards?

Yes, these carriage bolts conform to DIN 603 standards.

Troubleshooting

Bolt spins in the hole during tightening

Ensure the square shoulder has been fully seated into the wood using a mallet or hammer before applying the nut.

Threads feel stiff or seize during installation

Apply a stainless steel anti-seize lubricant to the threads; stainless steel can seize if tightened too quickly due to friction.

Wood is splitting during bolt insertion

Verify that your pilot hole is properly aligned and check if a larger pilot hole is required for the specific density of the timber.

Pros and Cons

Pros

  • Excellent resistance to rust and environmental corrosion
  • Anti-spin shoulder simplifies one-person installation
  • Durable A2 grade stainless steel suitable for outdoor use
  • Professional finish with the clean dome head design

Cons

  • Nuts are not included in the package
  • Requires pre-drilling of holes due to the M12 diameter
  • Stainless steel can be prone to galling if overtightened

Setup, Compatibility & Care

For optimal results, always use a drill bit slightly larger than 12mm to ensure a smooth fit. To prevent galling (the seizing of threads when tightening stainless steel), it is recommended to apply a small amount of anti-seize lubricant or wax to the threads before applying the nut. When installing into hardwoods or Green Oak, a pilot hole is essential to prevent the wood from splitting. Store these bolts in a dry place before use to maintain the integrity of the stainless steel finish. Ensure you source matching M12 stainless steel nuts, as they are not provided with these carriage bolts.
