Hague Fasteners – The Emergency Breakdown Bolting Solution
Special Fasteners installed around the World are seen in every conceivable use with the letters “HF” marked clearly on the heads.
Although Hague Fasteners only manufacture small quantities of very specialist fasteners, a tremendous fastener history since 1971 means Millions of custom fasteners have been manufactured I the heart of England and shipped to countries in all four corners of the World with the heads marked with The Hague Fasteners Ident HF.
These 2 letters, H and F are a symbol of quality British fastener manufacturing excellence and give piece of mind to engineers and fitters in every industry.
Hague Fasteners are often the preferred source for Superalloy and all bolting materials manufactured bolting for many Fastener Stockists and Distributors and OEM end users often ask themselves why bolts and fasteners are a hard stamped with the letters HF and numbers.
Bolt heads and fasteners in general are typically marked with the manufacturers identification and the material grade, so wherever there is a bolt marked HF you can rest assured it is a quality assured piece of British Engineering made in the UK by Hague Fasteners.
Hague Fasteners are experts in small batch Special Fastener manufacturing.
Often the manufacturing requirement originates from the OEM, the original equipment manufacturer where the bolt design, material specification and electroplating specification is governed by a Company specific documented specification. These specifications are often requested even when the special fastener in question is being manufactured for an intermediary, a fastener distributor, or the OEM’s subcontractor.
Hague Fasteners can supply manufacture non standard fasteners, non standard socket screws and Special fasteners with any surface coating.

The ultimate non-magnetic stainless steel fasteners are manufactured in extremely small quantities by Hague Fasteners.
The high Nitrogen content of ASTM A193 B8LN fasteners (304LN fasteners) creates an extremely low level of magnetic permeability and these special fasteners are used when is used where an extremely low level of magnetic permeability is required.
Special Fasteners in this specific stainless steel further exhibit the following desirable properties:-
Moderate pitting and crevice corrosion resistance
Excellent impact toughness at sub-zero temperatures
A higher proof stress yield than regular 304L stainless steel fasteners.
Non-magnetic, Very low ferrite level and very resistant to martensitic transformation. Relative magnetic permeability < 1.005
Good weldability.
304LN was originally developed as a higher strength version of 304L by raising the amount of nitrogen. However, the increase in strength is only modest and easily achieved through cold working. Further, duplex grades are now commonly used where higher strength bolting is required.
The grade is now used in specialised applications where a very low magnetic response is needed. In standard 304L, a typical level of relative magnetic permeability is around 1.05-1.1 due to small amounts of ferrite in the austenitic structure. A completely non-magnetic material would have a value of 1.0. 304LN can achieve a maximum value of around 1.005, which is the lowest practical level of any steel grade. It is also very resistant to transformation to the magnetic martensitic phase which can occur on forming or cooling to very low temperatures.
For this reason Hague's manufactured B8LN Special Fasteners are commonly used in specialised equipment where magnetic “interference” needs to be avoided and also for use in cryogenic equipment such as bolting for Magnetic resonance imaging (MRI) scanners, reinforcing foundation bolts for structures surrounding MRI scanners also special fasteners in pressure vessels, and non standard socket screws in cryogenic applications.
Many of the NonStandard Socket screws Hague Fasteners manufacture are made to customers specific designs and drawings, however Hague Fasteners have recently seen a sharp increase in the number of Standard Socket Screws they are being asked to manufacture.
Due to exceptional demand, new production methods have been recently introduced to ensure Hague can meet the growing demand for regular Socket Screws where Customers specifications now dictate the preferred Country of manufacture to be of EU or UK origin, and where full certification is required.
Hague Fasteners pride themselves on only using British or European Alloy Steels in the production of their Special Fasteners. Certification is the norm not the exception and they are always supplied as a matter of course Free Of Charge.
Hague Manufacture all Standard Socket Screws in any materials more commonly to dimensions stipulated in the following international standards:
DIN 912 Socket Capscrews
DIN 6912 Socket Capscrews

Hague Fasteners – UK manufacturing of Standard & NonStandard Socket Screws since 1971.
For over four decades Hague Fasteners have excelled in the manufacture of Stainless Steel Fasteners.
One of the most popular Martensitic grades in the Fastener world is the 15Cr2Ni 431 Stainless grade from the original EN57 through the Aerospace release grade S80 Specification, 431 offers fair corrosion resistance with good strength and impact resilience.
Our 431 Special Bolts and Non Standard Socket Screws are specified due to various factors including:-
• Fair corrosion resistance
• High hardness and strength
• Wear resistance
• Controlled balance of mechanical properties by hardening and tempering
• Improved toughness
• Magnetic
Due to the favourable properties exhibited, 431 Fasteners are manufactured and supplied by Hague Fasteners into a wide range of engineering applications around the World such as:
Bolting and fasteners for Drive shafts, propeller shafts, bearings, gears, hydraulic rams, valve stems, actuators, satellite parts, conveyor drive systems, packaging machinery and crane pins.
If you need a 431 Stainless threaded fastener, Hague Fasteners are on hand to turn your designs and drawings into quality assured components.
Hague Fasteners are one of the UK’s longest established manufacturers of Non Standard Socket Screws.
Our Socket Screws are often manufactured to common global standards but we are different in that we manufacture in material grades over and above those supplied by other NonStandard Socket Screw manufacturers. Often companies will only modify existing imported bulk produced screws sourced from the Far East, however due to the criticality of all components we supply we pride ourselves in being one of the few manufacturers that supply manufactured Socket and Allied products from UK sourced Alloy Steels, through hardened and tempered to meet the requirements of ISO 898 Part 1 Grades 8.8 10.9 & 12.9
Hague Fasteners, Non standard socket screw manufacturing since 1971.
Our Socket capscrews are manufactured to all international standards such as DIN 912 DIN 6912 DIN 7984 ANSI B18.3 ISO 4762 UNI 5931 NFE 25125 BS 2470 BS 4168 1936 Series 1960 Series Type CX but our forte is in the Custom Socket Screws made to Customers own critical designs and drawings particularly when superalloys are specified.
For years we have perfected the manufacture and supply of Heat resistant Non standard socket screws used in sensitive environments in superalloys such as Nimonic 80A, Hastelloy C276 & Monel 400. We often manufacture Special Socket Screw products with modified “undersize” threads to allow for component expansion in extreme working environments.
As proud British manufacturers we welcome all enquiries for NonStandardSocketScrews from 1pc or 10pcs, 25pcs through 100pcs to 500pcs, no enquiry is too small for our custom manufacturing.
