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.
The tapped hole shall be to the tolerance 4H or, if it is not critical application a medium 6H tolerance can apply.

Hague's "Special Fastener Gallery" Getting Record Number Of Visitors

Hague Fasteners have been amazed with the popularity of their Live updated Special Fastener Gallery feature on their recently re-launched website.
Even before the site has had time to be re-indexed by Google, the number of hits has exceeded all expectations with the Gallery being visited by over 70% of visitors every day.

The exciting Gallery feature was built into the new site as a way of showcasing some of the infinite array of Non Standard Fasteners, Non Standard Socket Screws and Non Standard Items to OEM drawings.
Hague Fasteners appreciate that whilst they may publicise their expertise in manufacturing Custom Wheel Studs, for example, this may not pique the interest of buyers seeking Custom Tie Bars or Square Head Bolts. It is this “pigeon hole’ing” that has been a source of frustration for the Sales Team at Hague Fasteners who desperately want to showcase Hague’s full capacity and capabilities.
The Special Fastener Gallery is the perfect solution, with new images constantly being added before new manufactured non standard bolts and nuts are packed and shipped to all industries around the World. You will always see the latest new images first as you revisit the Gallery page of the Website.
The Hague Fasteners Brochure can only ever give a very broad outline of the Fastener Manufacturing capabilities, so enjoy the live Showcase and learn more about the infinite range of fasteners Hague can supply at www.HagueFasteners.co.uk
