Bespoke Fasteners

Small Quantity Manufacturing Without Idle Claims

Countless companies offer bold claims like “if its standard we stock it, if its non-standard we stock it too”.

Here at Hague Fasteners we offer a simple and substantiated claim. If its not available from stock we will manufacture Bespoke Bolting for you in whatever delivery time you need.

There is no way anyone can stock special hex bolts, nonstandard socket screws or custom hex nut that’s not even designed yet, but once you’re happy with your specification you can source it from Hague Fasteners, manufactured to order, often as fast as if it were in stock, if required.

Being in the Special Fasteners industry for over forty years we know almost everyone claims they can make any specials that are beyond the standard stocked range. The reality unfortunately is not always quite so simple.


That fine thread BSF to UNF Tapping Thread Adaptor that’s non-standard, sure it can be made for you by standard stockists but do you really want to order 50,000pcs and wait 20 weeks? Just last week Hague Fasteners produced and supplied 4 off 1/2″ / M18 Tappex type self cutting thread adaptors in stainless steel in just a few days.

Hague Fasteners have decades of manufacturing expertise producing small quantity special components to all industries around the World, from Major Multi National Corporations to Small Self Employed Operators such as Modern Artists, Entrepreneurs Prototyping or Small Racing Engine Tuning experts.

What is an Engineer Stud ?
There are various key identifiers when it comes to specifying an Engineer Stud. Many international standards exist and Hague can manufacture to the dimensions required under all standards or indeed a bespoke special stud can easily be made to your unique requirements and drawings.


The Metal End is the Stud End that is screwed into the existing component base or body. This is generally 1 or 1.5 times the nominal diameter as specified by purchaser or international standard.
TheNut End is the Stud End which is not screwed into the existing component. A nut is tightened into this shorter threaded end to secure the fixing.
The Plain portion is the part of stud which is not screwed. This shall be greater than 50% of the nominal dia and normally includes thread runouts.
Nominal length- The British Standard BS4439 identifies a range of Nominal lengths from 12mm to 500 mm. The nominal length is the plain portion length & the Nut Threaded End added together.
d – Hague regularly manufacture Engineer Studs in the diameter range M6 (1/4″) through M100 (4″).
Threads Notes
According to the BS4439 standard the threads on the nut end and on the metal end shall be in accordance with BS 3643 parts 1-3. The nut end shall be to the tolerance 6g (medium fit.). This is as normal for a general bolt. The metal end shall be to the tolerance of a close fit (4h) or an oversize tolerance as specified.
