Special Fasteners Manufacturer in the UK
Hague Fasteners is a UK manufacturer of special fasteners and bespoke bolting, producing non standard and custom made fasteners to customer drawings and specifications. We specialise in small batch manufacture for safety critical applications, supplying special fasteners for nuclear, defence, oil and gas, power generation and heavy engineering sectors where quality, traceability and technical control are essential.
What Are Special Fasteners?
Special fasteners are non standard fasteners manufactured to specific customer requirements where catalogue or off the shelf components are unsuitable. They are typically defined by unique dimensions, non standard threads, special materials, or enhanced performance requirements, and are commonly used in safety critical and regulated engineering applications.
-
Unusual diameters, lengths, head forms or drive features
-
Non standard or special thread forms
-
High performance and exotic alloys including Inconel, Hastelloy, Duplex, Super Duplex, Monel and Nimonic
-
Reverse engineered fasteners for obsolete or legacy equipment
Bespoke Special Fasteners Manufactured to Customer Drawings
We manufacture bespoke special fasteners strictly to customer drawings, CAD models, and approved samples. Our production processes are supported by full dimensional inspection, material traceability, and certification, ensuring suitability for safety critical and regulated applications. Material options and datasheets are available in our Materials & Alloys section, with sector specific experience detailed in Industries We Support.
Quantity Flexibility for Bespoke Special Fasteners
Unlike volume driven fastener suppliers, our manufacturing model is designed around bespoke special fasteners produced in controlled quantities. This allows us to support development work, maintenance requirements, and ongoing production without forcing customers into unsuitable batch sizes.
-
One off prototypes and pilot components
-
Small batch production including 5, 10, 25, 50 and 100 pieces
-
Repeat manufacture and scheduled supply for mid volume special fastener requirements

Special Fasteners: Frequently Asked Questions
What qualifies as a special fastener?
A special fastener is any fastener manufactured outside standard catalogue dimensions or specifications. This may include non standard sizes, special thread forms such as UNJ, UNR, Metric Fine or Whitworth, unusual head forms, upgraded materials including Inconel 718 or Hastelloy C276, or specific coating, testing or certification requirements.
Can you work from a sample or damaged part?
Yes. We can reverse engineer special fasteners from physical samples or damaged components using dimensional measurement and verification, then manufacture replacements to the recovered specification with appropriate inspection and certification.
What are typical lead times for special fasteners?
Lead times depend on material availability, manufacturing complexity, and any required testing or certification. One off and small batch special fasteners can often be produced quickly, with urgent breakdown and outage requirements prioritised wherever possible.
Do you manufacture special fasteners in the UK?
Yes. All special fasteners are manufactured in the UK, with controlled processes, inspection, and full material traceability supporting safety critical and regulated applications.
