Fastener Manufacturers UK | Bolt, Nut & Screw Manufacturers UK for North Sea Energy, Automotive, Aerospace and Rail
The UK’s industrial procurement environment is one of the most standards-driven in the world. From North Sea oil and gas platforms to Tier 1 automotive plants, aerospace primes, and Network Rail infrastructure projects, UK buyers specify fasteners against BS, BS EN, ISO, and ASTM standards with a rigor matched by few other markets. Jade Alloys is a fastener suppliers UK engineering procurement teams turn to for ASTM, BS, and ISO certified bolts, nuts, and screws, manufactured at our own ISO 9001:2015 certified facility in Mumbai and exported directly no re-stamped Mill Test Certificates, no intermediary markup, one accountable supply chain from raw material to finished product.
As fastener manufacturers UK buyers rely on for both standard stock and project-specific runs, we supply the complete fastener range hex bolts, stud bolts, heavy hex nuts, socket screws, and specialty grades in stainless steel, alloy steel, carbon steel, duplex, and nickel alloys with EN 10204 3.1 Mill Test Certificates and full heat-number traceability on every shipment. Our UK-facing export desk manages Felixstowe, Southampton, and Tilbury Port documentation end to end, including UKCA marking guidance, REACH declarations, and Certificates of Origin for post-Brexit customs clearance.
Sea freight from Nhava Sheva Port, Mumbai to Felixstowe or Southampton typically takes 18 to 24 days. Air freight to London Heathrow (LHR) or East Midlands Airport (EMA) delivers within 3 to 5 business days for urgent MRO, planned turnaround, and production-critical requirements. DAP and DDP Incoterms are available to project sites and distribution centres across England, Scotland, Wales, and Northern Ireland.

Bolt Manufacturers UK — ASTM & BS Product Range
As bolt manufacturers UK buyers across North Sea energy, automotive, aerospace, and rail specify against, Jade Alloys carries the complete ASTM and BS EN bolt range. Browse our product ranges below:
Bolts Product Range (ASTM Standards): ASTM A325 Bolts | ASTM A320 L7 Bolts | ASTM A193 B7 Bolts | ASTM A193 B16 Bolts | ASTM A193 B8 Bolts | ASTM A193 B8M Bolts | ASTM A193 B8C Bolts | ASTM A307 Bolts | ASTM F568M Bolts | ASTM F3125 Bolts | ASTM A453 Grade 660 Bolts | ASTM F468 Bolts
Bolt standards reference: BS EN ISO 4014 (hex head bolts, product grades A and B), BS EN ISO 4016 (product grade C), BS 3692 (precision hexagon bolts, screws and nuts — metric series), BS 4190 (ISO metric black hexagon bolts, screws and nuts). Full standards library available on our Standards Reference Hub (ASTM, ASME, BS, DIN, IS, ISO).
Nut and Bolt Manufacturers UK — Complete Fastening Systems
As nut and bolt manufacturers UK project engineers specify matched fastening systems from, Jade Alloys supplies bolts and their corresponding nuts, washers, and locking hardware as a single traceable batch — matching heat numbers, thread tolerances, and property classes across the full assembly. This matters most on projects where mixed-source fasteners (a bolt from one supplier, a nut from another) can create thread-galling risk or MTC traceability gaps that fail EPC audit.
Nuts Product Range (ASTM Standards): ASTM A563 Nuts | ASTM A194 Grade 2H Nuts | ASTM A194 Grade 4 Nuts | ASTM A194 Grade 7 Nuts | ASTM A194 Grade 8 Nuts | ASTM A194 Grade 8C Nuts | ASTM A194 Grade 8T Nuts | ASTM A194 Grade 8S Nuts | ASTM A194 Grade 8M Nuts | ASTM F594 Nuts | ASTM F467 Nuts
Nut standards reference: BS EN ISO 4032 (hexagon nuts, style 1), BS EN ISO 4033 (style 2), BS EN ISO 4034 (product grade C), BS 3692 (precision hexagon nuts — metric series).
Screw Manufacturers UK — Machine, Socket & Self-Tapping Screws
Alongside our bolt and nut range, Jade Alloys is one of the screw manufacturers UK precision engineering, automotive, and MRO buyers rely on. We manufacture machine screws, socket head cap screws, self-tapping screws, and set screws in stainless steel (SS 304, 316, 316L), alloy steel, and carbon steel to BS EN, ASTM, and DIN standards, in sizes from M1.6 to M12. Screws ship with the same EN 10204 3.1 documentation as our bolt and nut range and are available in knurled, flat, dog, and cone point configurations.
Screw standards reference: BS EN ISO 4762 (socket head cap screws), BS EN ISO 4017 (hex head screws, full thread), BS EN ISO 7045 (pan head screws with cross recess).

UK Import Compliance Guide — UKCA, REACH and Customs
Since the UK’s departure from the EU, product conformity marking has diverged from the CE marking system used in the EU. UK buyers and their suppliers need to understand which marking regime applies:
- UKCA Marking: The UK Conformity Assessed mark applies to most industrial goods placed on the market in England, Scotland, and Wales. Fasteners supplied as components into machinery, construction products, or pressure equipment are generally assessed under the relevant UK regulations rather than requiring standalone UKCA marking on the fastener itself — confirm the applicable regime with your UK procurement or compliance team for your specific application.
- Northern Ireland: CE marking (or the UKNI mark alongside CE, where applicable) continues to apply for goods placed on the market in Northern Ireland under the Windsor Framework — a separate compliance path from Great Britain.
- REACH: The UK operates its own REACH regime (UK REACH) separate from EU REACH post-Brexit. Jade Alloys provides material composition declarations on request to support UK REACH compliance assessments.
- Certificates of Origin: Required for UK customs clearance; issued for every shipment from our export desk.
- EN 10204 3.1 Mill Test Certificates: The standard documentation UK EPC contractors and quality teams expect on pressure-critical and structural fastener orders supplied as standard, not as a chargeable extra.
Jade Alloys’ UK export desk can advise on which specific documentation your project requires, but final compliance responsibility for UKCA/CE marking and use-case classification rests with the UK importer or the machinery/assembly manufacturer incorporating the fasteners.
