Small Enough To Care : Big Enough To Deliver (since 1971)
MP35N Special Fasteners Focus For Subsea & Offshore Oil and Gas Engineering.
MP35N (Ni Co Cr Mo 35 35 20 10)
is a nickel-cobalt base alloy that is often specified in subsea special fastener designs due to its unique combination of properties – ultra high strength, toughness, ductility and outstanding corrosion resistance.
Hague Fasteners’ manufactured critical special fasteners are, by virtue of the alloy, work strengthened and finally aged to obtain strength levels of 260 to 300 ksi (1793-2086 MPa) in its full strength condition. With less cold work reduction, the alloy has the best balance of strength and stress corrosion cracking resistance (SCC) for harsh environments.
Hague’s MP35N custom fasteners resist corrosion in hydrogen sulfide, salt water and other chloride solutions, as well as the mineral acids (nitric, hydrochloric, sulfuric). In addition, all critical manufactured special fasteners exhibit exceptional resistance to crevice corrosion cracking in seawater and other hostile environments hence being a popular choice for high integrity applications in offshore and subsea industries.
HEAT TREATMENT (AGING)
MP35N should be aged at the temperature required to achieve the final properties desired. The amount of cold work in MP35N defines the recommended aging treatments.
For AMS 5844 (full strength/ heavily cold worked) material, the alloy should be aged at 1000°F – 1200°F for 4 hours.
For optimum sulfide SCC resistance, less-heavily cold worked material can be aged at 1300°F or 1350°F for 4 hours or at 1425°F for 6 hours as indicated in NACE MR-0175. The 1425°F aging treatment provides the best sulfide SCC resistance, but at the expense of strength.
Exposure to temperatures much above the recommended aging temperatures may result in a significant (and non-recoverable) loss in strength caused by the reversion of the cold-worked metallurgical structure to the much softer annealed structure.
Hague Fasteners are manufacturing every type of conceivable special fasteners and turned components for use in Downhole pump drive shafts assemblies and associated tooling.

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.
We are proud to have worked on a Manifold bolting solution to a Private Raceteam this month that solved a failing bolted connection at high temperatures and secured Pole Position, a record lap time, and a First Place Podium Finish.
Small Quantity Bolting Solution Providers since 1971.
No idle claims just real results.
For over 4 decades, Hague Fasteners have excelled in the quality manufacturing of Engineer Studs.
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.
Great to announce that our Website & SEO partners at Red Media are working on our optimised Mobile site.
Hague Fasteners set the standard back in 1971 when they were established in their earliest form. Hague only deliver quality-assured special fastener products in European and American sourced materials.
Hague’s full range of quality-assured special fasteners ensure peace of mind in critical and severe operating conditions.
Hague produce & supply more than a million fasteners a year into worldwide industries, assuring a credible UK manufactured product that is certified to whatever level of quality assurance is required.
We use the most current tests including:
Mechanical testing:
full dimensional inspection, axial and wedge tensile test, compression test, proof load test, hardness tests (Rockwell, Vickers, Knoop).
Metallurgical testing:
Coating and plating thickness, surface integrity, discontinuity, ductility, embrittlement, corrosion, neutral salt spray test, and joint testing. LPI & MPI. Ultrasonic and X-ray inspection.
Whatever your requirement, where unrivalled quality is required Hague is the answer and at a price that knocks competition into the background.

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
As part of our impressive Website relaunch we are excited to introduce our:-
Photo Gallery Of Special Bolting
This exciting ongoing presentation shows a large selection of the high integrity special fasteners and custom bolting manufactured by Hague Fasteners Limited.
The gallery is constantly updated with new photographs of Hex Bolts, Engineer Studs, and a wide array of Special Turned Parts manufactured in the UK by Hague Fasteners for Worldwide Engineering Industries.
Be sure to take a look at the Live Fastener Gallery and revisit often to see a large selection of the infinite product range that are impossible to catalogue.
Following the Company re-branding at the end of 2012, Hague Fasteners are proud to publish their new eBrochure.
As specialist manufacturers of Custom Fasteners to OEM drawings and designs, the range of products manufactured are immeasurable, however it is hoped that the new eBrochure indicates the massive scope of Hague Fasteners capabilities to Industries Worldwide.
