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.

Recently we supplied a customer with some bar turned 2BA Hex Bolts to a bespoke drawing for a Classic Car restoration project. The bolts where manufacured by our sister company Smith Bullough

Due to ongoing improvements in our manufacturing capabilities we are now able to supply more of the weird and wonderful threadforms in all shapes and sizes.

Look at this impressive M52 x 150 Grade 8.8 Bolt which has been manufactured in house on a CNC machine creating a single point cut thread.

This part has been produced to a high standard by our sister company Smith Bullough and is now ready to be shipped out to our customer!

We recently exported 1″ x 4″ BSW Setscrews Grade U BS 1083 to a client who was restoring old British made dryer cylinders on paper machines from pre 1970’s.

Grade U is not a popular grade in BSW but because of the amount of heat that the machines produce the client specificed Grade U, which will be safe in temperatures around 200 celcius.

Our sister company Smith Bullough manufactured these to specification in just 3 weeks which included forge, threading and heat treatment.

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.

We recently produced in our factory at Smith Bullough a part for the Offshore Industry. Tensioned risers (TTRs) have been used for deepwater applications in the Gulf of Mexico, offshore West Africa, and offshore Southeast Asia. Dry tree riser systems attached to floating production units such as spars, tension leg platforms (TLPs), and deep‐draft semisubmersibles are continually being considered for future developments, and designs have been developed for ultradeepwater. TTRs are complex dynamic structures, and the design of these riser systems is primarily governed by loading from the environment and the floater motions.

The assemblies are made from 2 riser bars, 2 studbolts and 8 full nuts.

The client wanted Western European Material with full traceability. This is no problem for us with our increased manufacturing capacity and knowledge of traceable materials to the original billets.
