17/4PH Fasteners

Grade 17/4 PH (1.4542) is one of the most common precipitation hardening stainless grades used for the manufacture of our Special Fasteners and our Non-Standard Socket Screws.

17-4PH has good corrosion resistance whilst also offering high strength and good impact toughness, vital properties in many special bolting applications.

17/4PH is often specified where the following characteristics are required:

• Good corrosion resistance (slightly less than a 304 stainless steel)
• High hardness and high strength
• Controlled balance of mechanical properties by ageing (precipitation hardening)
• Improved toughness compared to 431 stainless and critically at sub-zero temperatures in the softer conditions
• Magnetic
• Thermal expansion comparable to carbon steel
• Easier to weld than martensitic stainless grades like 420 and 431

17-4 PH develops its high strength from the precipitation of copper particles in its martensitic matrix. It comes in various conditions denoted by H plus the ageing temperature in Fahrenheit (°F), for example H900, H1025 etc.

The higher the ageing temperature, the lower the strength becomes and the higher the ductility and toughness develop. The minimum 0.2% Proof Stress values can vary from 520 MPa to 1170 MPa depending on the condition.

CONDITION A
Soak at 1900 F (1038 C) for 30 minutes and cool below 60 F (16 C) for complete martensite transformation.

CONDITION H950
Treat Condition A material at 900 F(482 C) for 1 hour, air cool.

CONDITION H925, H1025, H1075, H1100, H1150
Soak solution treated material for 4 hours at specified temperature, air cool.

CONDITION H1150M
Soak solution treated material at 1400 F (760 C) for 2 hours, air cool, then re-heat to 1150 F (620 C) for 4 hours and air cool.

The combination of high strength and good corrosion resistance finds special fasteners used in:
Drive shafts, gears, hydraulic rams, valve stems, load cells, tensioning systems, quick release pins, fasteners, aerospace, medical devices, food processing, conveying equipment and fall arrest systems

Investment In New Special Fastener Machinery

Jon Hague

Hague Fasteners have once again invested in increasing production capacity as sales records continue to grow reaching record breaking profitability levels not seen since the 1980’s.

This weeks new arrival at their Watery Lane Special Fastener Production facility sees CNC capacity increase by 20% since the start of the year.

Following the successful apprentice training schemes of 2013 Hague Fasteners are now seeing the skills acquired over the last 45 years being passed on to their new generation of Special Fastener technicians.

New advancements and investments in machine tools now sees Hague Fasteners massive diversity further increased, with the added ability to manufacture shafts and leadscrews with ACME Threads, Trapezoidal Threads and Square Threads, at more realistic prices than manufacturers that purely specialise in these thread forms.

Latest 3D modelling of special designed customer drawings now ensures manufactured Special Fasteners can be taken from a drawing to a physical component as if from stock.

It is a proud boast that Hague’s customer ethos can see an item made from round bar and supplied to a customer, faster than some bureaucratic fastener stockists need to pick from stock and make available for collection. A sorry state of a complacent fastener industry that Hague Fasteners have always been proud to be different from.

Customer Focus is always paramount – Let Hague Fasteners be your Special Fastener Solution.

UNS S31254 Fasteners

Jon Hague

The high integrity bolts and special fasteners that Hague Fasteners manufacture are often installed into highly aggressive environments.

Anti-corrosion materials are therefore commonly specified where reliance on a surface coating is simply impractical.

The 6% Mo Duplex Stainless Steel materials are among the best stainless steels for use in water and seawater giving excellent service in some very aggressive environments.

This various special fasteners including Hex Bolts, Eng Studs, Studbolts, Hex Nuts and Socket Capscrews Hague manufacture in 6Mo (254Smo) stainless are often specified due to the following characteristics:

• Comparable pitting and crevice corrosion resistance (PREN > 40, akin to SuperDuplex Fasteners.
• Excellent resistance to strong acids.
• Excellent stress corrosion cracking resistance.
• Higher yield strength than standard stainless steels available in Class 70 and Class 80 Cold Worked strength grades.
• Good impact toughness at sub-zero temperatures (even tougher than SuperDuplex grades).
• A cost effective alternative to some of the more expensive nickel base superalloys.

Hague Fasteners are manufacturing all types of UNS S31254 Special Fasteners and supplying global industry sectors such as:

Pulp and paper, Water Desalination Facilities, chemical processing plant, chemical tanker transportation, heat exchangers & Tubing Condensers, metal refining, flue gas desulphurisation (FGD), structural subsea fastener components, offshore oil and gas equipment, submarines & aggressive food processing manufacturing lines.

Whatever your application, whatever your design, you can trust Hague to manufacture and deliver Special Fasteners on time.

Special Fasteners, Spherical Washers

Spherical Washers

Jon Hague

The price of “off the shelf” Spherical Washer Sets, also known as Equalising Washers or Levelling Washers, is often quite shocking.

Hague Fasteners are increasing the amount of spherical washer sets they are manufacturing in Case Hardened Steel but more commonly in through hardened alloys and stainless steels.

Spherical washers are a perfect solution for ensuring there is an even clamping pressure on critical fastening applications, particularly where a slight modification to the installation levelling is required.

Hague Fasteners can manufacture split sets of levelling washers to drawings or to DIN 6319 but increasingly the call for Hague’s special non-separating sets is growing.

Covering all metric and imperial sizes, Hague’s unique design of non-detaching spherical washer sets are a much more economical solution than other commercially available levelling washer items.

The top half of the washer set has a convex shape and a smaller ID. It is secured to the bottom half concave washer that has a a larger ID. The free moving contained assembly allows for a levelling adjustment of up to 4 degrees angle.

The washer sets are precision machined from 316 stainless steel and through hardened class 10.9 carbon steel or indeed manufactured in ANY MATERIAL you need.

Due to the unique manner in which these non-detachable washer sets are assembled prior to delivery, any surface coating can be supplied, from Zinc & Blue Passivate, through Hot Dip Galvanised or Stellite, whatever is specified.

Subsea Fasteners

Jon Hague

Offshore Subsea Fasteners

The offshore oil & gas industry is one of the largest industry sectors Hague Fasteners service with their British Manufactured High Integrity Special Fasteners.

Hague Fasteners offshore oil and gas bolting are often used for high integrity systems where the reliability and critical quality are essential for the long term performance of the structures they are fitted to, none more so when used as structural components and for high pressure vessels and piping.

As with all of Hague Fasteners precision manufactured components it is of critical importance that the Custom Fasteners and Superalloy Bolting are manufactured, without deviation, to the Original Equipment Manufacturers designs that provide for the required service life for the various exposure and service conditions they are designed and exposed to.

Bolting can fail for a number of reasons (e.g. overload, fatigue or corrosion). The materials selection, manufacturing methods, bolt fabrication, protective coating and the installation are all critical and need to be strictly adhered to, thus ensuring that long service performance is guaranteed. The actual service conditions and the external environment impact and maintenance will subsequently determine the service life of the bolting.

With over 40 years of Subsea Engineering experience Hague Fasteners turns your critically specified designs and drawings into High Integrity Quality Assured bolts ready to fit and install within hours where necessary. Hague Fasteners original concept of a”Breakdown Delivery Service” is as real today as it was 40 years ago.

Whatever the material, whatever the design, whatever the delivery, Hague Fasteners is your solution.
