Stay Nuts

Friday 13th July 2018

STAY NUTS Trojan just manufactured some Stay Nuts in three different sizes using the same batch of material. You may notice that dimensionally these nuts are all the same size except for the internal threaded portion - thats different. We manufactured these for a Boiler Restoration specialist based in England who happens to go through so many of these and we're grateful for his custom. Stay nuts are fastened onto Boiler Stay Bolts. Using one across flat (head size) means that tooling is reduced and they can be assembled onto the boiler pretty quickly. These type of nuts are used quite extensively in the railway locomotive boiler restoration industries. They are single chamfer and single countersunk too - just aids application and…

Connector nuts with viewing port

Wednesday 13th June 2018

Trojan just manufactured 4 different sizes of these extra long connector nuts.

The fasteners you see here have an M30 thread and are 75 millimeters long with double chamfers.

Special Zinced Spacers

Tuesday 12th June 2018

Check out these beautifully machined spacers. Well, you might ask, why would someone need a spacer?

Each plate assembly requires four of these spacers for the four bolts that hold the plate apart the required distance for the other moving parts that attach to said plate. We can manufacture spacers from single to multiple thousand quantities, all bright bar turned and in whatever feasible plating or coating we can get from our…

M16x1.5 special nuts to drawing

Friday 1st June 2018

Fasteners such as these present their own manufacturing problems - such a small wall coupled with a short height mean that we had to manufacture some special tooling in order to just thread them. They're precision machined to perfection and do the job as intended... just hope the customer doesn't over torque them!
