Extended Product Information

FAQs

Are nuts included with these bolts?

No, nuts are not included with this product.

Are these bolts fully threaded?

These bolts are fully threaded up to 150mm; since this specific model is 100mm, it is fully threaded.

Can I use these near the ocean?

Yes, A2 stainless steel provides excellent corrosion resistance, making them suitable for most external environments, including coastal areas.

What is the thread diameter?

The thread diameter is M12.

Why use stainless steel instead of galvanized steel?

Stainless steel provides significantly higher resistance to long-term corrosion and environmental chemical reactions compared to galvanized or zinc-plated coatings.

Troubleshooting

Bolt rotates while trying to tighten the nut

Ensure the pilot hole is clean and the square shoulder is fully tapped into the timber surface to create a proper friction lock.

Nut feels stuck or becomes difficult to turn during installation

Stainless steel can gall under high heat/friction; ensure the threads are clean and consider using an anti-seize lubricant.

Pros and Cons

Pros

  • Superior corrosion resistance compared to zinc-plated alternatives
  • Anti-spin shoulder simplifies installation by preventing rotation
  • Durable stainless steel construction maintains structural integrity
  • Aesthetic dome head profile for neat project completion

Cons

  • Nuts are not included and must be purchased separately
  • Stainless steel may be prone to galling if tightened excessively
  • Limited availability for specific thread-length variants

Setup, Compatibility & Care

To install these bolts, drill a clearance hole approximately 12.5mm to 13mm in diameter to ensure the shoulder can seat properly into the wood without splitting the timber grain.

Compatibility

  • Fastening: Use with M12 metric nuts and washers.
  • Materials: Compatible with softwoods, hardwoods, and reactive timbers like Green Oak.

Care

While A2 stainless steel is highly resistant to corrosion, it is not immune. In coastal areas or industrial zones with high salt or chemical exposure, periodically check for surface tea-staining. Clean with a soft cloth and mild stainless steel cleaner if environmental debris accumulates.
