FAQs

What size drill bit should I use?

Use a drill bit that matches the M10 diameter of the bolt.

What type of wrench is needed?

A standard wrench or spanner that fits the nut size.

Can these bolts be used with treated lumber?

Yes, but ensure the bolts are compatible with the treatment chemicals. Stainless steel bolts are a better choice for treated lumber.

Are these bolts suitable for outdoor use?

Yes, the zinc plating provides some corrosion resistance, but consider using stainless steel bolts for prolonged outdoor exposure or in harsh environments.

How do I prevent the bolt from spinning?

Ensure the square section is fully inserted into the timber and that the hole is not too large. Also, you could try using a washer under the head.

What is the recommended torque for tightening?

Tighten the nut until snug. Avoid over-tightening to prevent damage to the timber or the bolt.

Can I use these bolts with metal?

No, these bolts are designed specifically for use with timber.

Troubleshooting

Bolt won't tighten properly.

Ensure the square section of the bolt is properly seated in the timber. Check for obstructions in the drilled hole. Make sure you are using the correct size wrench or spanner.

Bolt is spinning during tightening.

Ensure the cup square head is firmly seated in the timber. If the hole is too large, the bolt may spin. Consider using a washer under the head to improve grip.

Rust or corrosion is present.

Replace the affected bolts. Consider using a sealant or protective coating to prevent further corrosion, especially in outdoor applications.
