Motorsport Project 1 1/2″ BSF Special Machined Stud – EN19T

Look at this magnificent part manufactured for a Motorsport project!

We were given a very worn sample of the 1 1/2″ Stud which was measured, tested and inspected by our qualified Engineers and QA team.

A drawing was then produced and approved allowing us to manufacture this impressive stud to a very high standard.

3/8 BSF Slotted Dog Point Grub Screw High Tensile

This week we supplied a new customer with some 3/8 BSF Slotted Dog Point Grub Screws for a Tractor restoration project.

Our customer wasn’t sure of the exact sizes so we obtained a sample to be measured and tested by our QA team. A drawing was then created and parts were manufactured by our sister company Smith Bullough.

We are continually improving our manufacturing capabilities which allows us to supply more of the weird and wonderful fasteners.

Metric & Imperial Nylon Insert Nuts

Nylon (Nyloc) Insert Nuts- BSW, BSF, UNC & UNF and Metric

A Nyloc (nylon insert) Nut is a torque prevailing nut which uses a plastic/nylon insert located towards the top of the nut, reducing its inner diameter, which then deforms over the mating thread.

Metric is very popular but the imperial sizes are becoming more obselete as demand drops.

Not to worry! Thomas Smith Fasteners stock a full range of all imperial diameters from 1/4″ to 1″ as we supply to many different industries including Classic Car Restoration & Heritage Rail.

You can order today via our online shop. If the item you require is not listed, we may still stock it or be able to source it.

Please contact us and we’ll be happy to help.


Last week our sister company Smith Bullough manufactured 3/4″ & 1″ Washers in S32760 (Super Duplex Material)

Why Super Duplex?

Super Duplex UNS S32760 is among the most common super duplex grade in the market. UNS S32760 is a duplex stainless steel especially designed for service in aggressive chloride-containing environments.

Below you can see how the material looked before we began manufacture, during the process and finally the finished product.

Our customer required an urgent turnaround on this order. Thanks to our expertise and machinery we were able to produce parts within 24 hours.

Almost 20 years since Fred Dibnah visited our factory!

We can’t believe it’s been almost 20 years since Fred Dibnah came to our factory to film an episode for his ‘Made In Britain’ series giving a grand tour of the wonderful manufacturing that took place many years ago which we still do today! When we were based in Atherton, Fred would visit regularly to purchase fasteners for his steam engine, he was a very charming and charismatic man who had a passion for Engineering.

In the last 20 years we have switched from furnace fired forges to induction heating, back then grade 8.8 (metric) and Gr S/R (imperial) was the limit on manufactured bolts, we can now produce high tensile grades up to 12.9 as well as many different materials such as Stainless Steels, Exotic Alloys, Super Duplex and Non-Ferrous.

Our machinery has also improved significantly allowing us to manufacture to a high specification. We offer CNC manufacturing in house, Cut & Roll Threading, plus Secondary Operations – Turning, Milling, Drilling and Grinding.
