zinc nickel special unc bolts

Thomas Smith Fasteners were delighted to help out a new client out in Abu Dhabi, UAE, who had an urgent requirement for special UNC bolts in Zinc/Nickel Plated.

These bolts, which were required for a power station, were manufactured in our machine shop before being sent to our local platers for the Zinc Nickel finish.

From receiving the order we were able to turn-around in just 4 working days.

Another satisfied customer!

We manufacture a wide variety of special fasteners in our onsite workshop, as these two recent examples demonstrate!

Our fasteners often have special head shapes or threadforms, for example these forged square square head blanks:

BSW Fasteners for Heritage Rail – Great Western’s 4079 restoration

Thomas Smith Fasteners supply many private & heritage railways throughout the UK.

We recently supplied the Great Western Society at Didcot Railway Centre in Oxfordshire, with BSW (Whitworth) bolts and nuts for a fantastic project to restore a member of the iconic Castle Class 4-6-0, the 4079 ‘Pendennis Castle’.

No.4079 ‘Pendennis Castle’ was the seventh of 171 Castles built and was completed at Swindon in February 1924.

After a long and distinguished service in which she outperformed many larger competitors, ‘Pendennis Castle’ was withdrawn in 1964, and sold for preservation. In 1977 the locomotive was sold to Hamersley Iron in Western Australia for use on excursion trains on the company’s ore-carrying railway.

In Australia, she was looked after by the Pilbara Railways Historical Society and worked many excursion trains, with her final steaming in Australia taking place in October 1994.

With an operational future in Australia looking uncertain, in early 2000 the Great Western Society agreed to arrange and pay for the repatriation of ‘Pendennis Castle’ and to restore her to full operational condition.

The Great Western Society have very kindly provided us with this photographs of the rebuild featuring our bolts, nuts and fasteners.

Here is a front view of the locomotive, the boiler & smokebox have yet to be fitted.

Great Western also use our fasteners for bolting pipe flanges together and general engineering purposes.

Classic Ferrari 365 GTC/4 Restoration part 7

The car was assessed by the new repairers in my garage at home in late December 2013 and it was agreed that the car be transported to their place and they would start work early in 2014.


The engine was taken out and stripped down. The block and head have been pressure tested and are fine. This is a great relief as cracks in either of them would have been a major problem.


The problem that caused the oil/water mix has been tracked down to the failure of the oil/water common pump unit. The bearings had disintegrated and the shaft was flopping about. Also internal gears had badly scored the inner casing.



While the engine was out the radiator has been re-cored, serviced and returned looking as new! Whilst the engine is out all things that need the engine to be out will be repaired, eg new engine mounts, an aircon condenser unit will be sourced as the original is missing. More to come on the engine and car rebuild in the coming months.
