Steel Bar Cutting

Hague Fasteners are please to take delivery of another new steel bar Cutting machine to our ever expanding Special Fastener Production Facility.

Our new Steel Bar Cutting NC controlled automatic bandsaw is optimising our incoming material (up to 300mmø) ready for our in house special fastener manufacturing.

This new investment has been made due to Hague’s ever increasing order book and with the sawing often being the first stage of production. This new plant sees material received and processed much faster and with higher accuracy.

Whilst Hague Fasteners specialise in the smaller batches of custom made special fastener components, the new Steel Bar Sawing machine also gives flexibility of cutting larger batch runs. Where needed the NC can control various billet length cuts from a single bar set-up.

The accurate NC controls also enable the optimum speed and feed rates when cutting some of the super alloys and Nickel based materials such as Nimonic, Hastelloy, Inconel and so on.

Continued growth and investment assured Hague’s clients of the very best in customer service and reliability.

Special Fasteners Fixing Global Industry

When others fail to deliver, you can rely on Hague Fasteners to deliver.   This week we recieved a request to supply over 1500kgs of Custom Manufactured SuperDuplex Hexagon Bolts & Nuts in less than 5 days. 

Within 24 hours of winning the order the round bar material hit our production facility in the heart of the UK and our loyal team set about the massive task asked of us. 

The customer service ethos throughout every member of Hague Fasteners staff guaranteed that our Customer would have the order in hand when needed, regardless of the challenges that would undoubtedly crop up despite perfect planning and scheduling. 

It is the pride and sense of achievement that sets Hague Fasteners apart, often taking control of another Fastener Suppliers failure to deliver and acting with complete sense of purpose to minimise Plant downtime and financial penalties. 

It was pointed out, after completing production in less than 72 hours, that other fastener companies take longer to supply the certification for their supplies than it takes Hague Fasteners to manufacture and deliver 1.5Tonnes of Super Duplex Fasteners. 

As the original Breakdown Bolting Service Providers, Hague Fasteners have been doing this for 44 years, why go anywhere else ?

Hague Fasteners: Big Enough To Deliver, Small Enough To Care.

Power Generation Fasteners

Hague Fasteners are once again making a massive impact into the British Power Generating Industry.

Hague Fasteners Durehete Stud
CEO Jon Hague with the months largest Turbine Stud as it leaves to repair a UK Power Station

For the last decade or so the Power Generation bolting supply chain has seen an influx of “non” Durehete grades of material, Global Equivalent grades or even custom branded equivalents that often do not tick all of the original CEGB requirements.

British manufacturing of 100% approved British Durehete material could not always compete with the imported equivalents and so Hague Fasteners respectfully backed away from an ever increasingly competitive market that saw quality standards and approvals decline.

2014 has seen a massive shift back to 100% original CEGB British manufactured Power Generation Turbine Studs & Cap Nuts, it seems the industry as moved back to their roots, in much the same way as the Subsea procurement marketplace a decade before, in stipulating the highest integrity material and unquestionable British Manufacturing and Customer Service excellence.

Working as a key manufacturer to the Power Generation sector and associated service industries since 1971, Hague Fasteners are once again breaking the mould and reinforcing the Best of British.

We never cut corners to win orders.
