Collection: Stainless Steel Coach Bolts

Stainless Steel Coach Bolts (Carriage Bolts) | Fixabolt®

The bolt that locks in from one side. Ideal for timber. Built for the trade.

Fixabolt® stainless steel coach bolts, also known as carriage bolts, are designed for timber-to-timber or metal-to-wood fixings where a clean finish and secure hold are key. Featuring a domed, low-profile head with a square neck beneath, these bolts are made to grip into the material and prevent rotation as the nut is tightened. Perfect for applications where you can’t access both sides with a spanner.

Whether you're working on wood projects, construction gigs, or tackling structural masterpieces, coach bolts can be your go-to.

What are Coach Bolts Used for?

Coach bolts are a go-to for structural woodworking, fencing, decking, outdoor furniture, and other heavy-duty timber fixings. Just tap the bolt through a pre-drilled hole, the square section bites into the wood to stop it spinning while you tighten from the nut side. No need to grip the bolt head. Great for:

• Timber framing
• Sleepers & landscaping
• Pergolas, gates & fencing
• Decks and garden structures
• Metal-to-wood fixings using brackets or plates

Coach Bolts vs Coach Screws - What's the Difference?

We get this a lot. Coach bolts (a.k.a. carriage bolts) have a machine thread and are used with a nut. Coach screws, on the other hand, are self-tapping screws with a hex head and no nut - perfect for screwing directly into timber.

Coach Bolt FAQs

Q: Can coach bolts be used outdoors?

Yes, especially in stainless steel. A2 grade bolts are perfect for outdoor and moist environments.

Q: How do coach bolts stay in place?

The square neck below the dome head bites into the timber when tapped in, preventing rotation as the nut is tightened.

Q: Can I use coach bolts for metal fixings?

They’re mainly for wood or wood-to-metal. For metal-to-metal, you’ll need a square hole or a different type of bolt.

Q: Are coach bolts the same as carriage bolts?

Yes, coach bolts and carriage bolts are different names for the same product.

Q: What tool do I use to tighten coach bolts?

You’ll only need access to the nut side. Use a spanner or socket. No tool required on the smooth bolt head.

Q: Are coach bolts strong enough for structural work?

Absolutely. Just make sure you select the right size and stainless grade for the job.
