FAQ’s
Why should I use Joyner Bolts instead of Coach Bolts?
Coach Bolts are a generic fixing. As a result were not designed to specifically fix timber together. The round domed head makes it impossible to grip or restrain when it starts to move, meaning the joint will not be tight. If the joint is not tight and shear force is applied to the shank of the bolt it will fail/break. No such problems with Joyner Bolts. The spiked head grips the wood removing the possibility of any turning. This means you can increase the torque on the bolt.
I use threaded rod. It’s cost effective as I can cut it to the size I need. Why are Joyner Bolts better?
Using threaded rod is only cost effective in the initial purchase price. The time it takes to cut each piece of rod to the required length, then to purchase the additional nuts and square washers, factor in the waste and the need to hold both nuts with separate spanners to tighten….it actually makes threaded rod more expensive. Furthermore, once the rod is cut the protective coating is lost. Joyner Bolts are task specific. You simply buy the bolt for the job needed. No cutting, no waste, no lost time…Job Done.
How much more expensive is it than a coach bolt?
Approximately twice as much, but the time saved in using Joyner Bolt far out weights the initial small cost difference. See our Walworth Road Case Study.
Does Joyner Bolt have a CE mark?
Yes, undertaken by Timber Research and Development Association.
What grade steel is Joyner Bolt made from?
Joyner Bolts are made from standard carbon steel 4.8 grade.
Can I use Joyner Bolt with an oak framed building?
Using bright zinc-coated bolts with oak is not generally recommended because oak contains tannins, which can react with zinc and cause corrosion or staining. Over time, this can lead to the breakdown of the zinc coating and the formation of unsightly black stains where the bolt meets the wood.
Alternatives:
- Stainless Steel Bolts: Stainless steel is highly resistant to tannin corrosion and is the best choice when fastening oak.
- Galvanized Bolts: Hot-dipped galvanized bolts can be more resistant than zinc-coated ones, but they may still be affected by oak’s tannins over time.
- Brass or Bronze: These materials are also suitable for use with oak, as they do not corrode or stain in the presence of tannins.
For long-lasting performance and aesthetics, stainless steel is the preferred option when working with oak.
What sizes does Joyner Bolt come in?
M10: 80mm, 115mm, 125mm, 180mm, 230mm.
M12: 80mm, 115mm, 125mm, 180mm, 230mm.
What size pack can I buy Joyner Bolt in?

Do Joyner Bolts come with washers?
No, but they can be bought separately from us.
Do Joyner Bolts come with nuts?
Yes absolutely! What’s the point in getting a bolt without the nut!
