FAQs

Are the nuts included with these bolts?

No, nuts are not included and must be purchased separately.

Are these bolts suitable for use in salt-water environments?

While A2 stainless steel has excellent corrosion resistance, A4 (Marine Grade) stainless steel is recommended for direct coastal or salt-water exposure.

What is the diameter of these bolts?

These bolts have a thread diameter of M6.

Can I use these on Green Oak?

Yes, A2 stainless steel is specifically recommended for use with Green Oak because it resists the corrosive tannic acids found in the timber.

What standard do these bolts follow?

These bolts conform to DIN 603 standards.

Is the bolt fully threaded?

Yes, this 100mm length is fully threaded.

Troubleshooting

Bolt spins while tightening the nut

The square shoulder is not fully seated in the wood. Tap the head of the bolt with a hammer to drive the square section into the timber.

Nut feels difficult to thread or binds

Stainless steel can gall under high friction. Back the nut off, clean the threads, and try tightening more slowly or apply a light lubricant.

Bolt is too loose in the pre-drilled hole

Ensure the drill bit used matches the M6 diameter. If the hole is too wide, the anti-spin shoulder may not grip effectively.

Pros and Cons

Pros

  • High-grade A2 stainless steel prevents rust in harsh weather
  • Square shoulder design eliminates the need for two-tool operation
  • Safe and attractive dome head profile
  • Reliable performance with corrosive materials like Green Oak

Cons

  • Nuts are not included with the bolt
  • Requires manual drilling for the pilot hole to accommodate the square shoulder
  • Limited to M6 diameter applications

Setup, Compatibility & Care

To install, drill an M6 hole through your timber components. Insert the bolt through the hole and use a hammer to lightly tap the dome head until the square shoulder is fully seated in the wood. Ensure you source matching M6 nuts and washers, preferably in A2 or 304 stainless steel to maintain the anti-corrosive properties of the assembly. While stainless steel is highly resistant, it can gall if the nut is tightened too quickly; using a lubricant or tightening slowly can prevent this. Keep the threads clean and free of debris during installation to ensure a smooth fit.
