Bolt and Nut Manufacturing (Tachart Ltd) - CNC Machined Parts

We produce CNC machined parts and are an experienced precision engineering company. As well as a wide variety of CNC machined parts, we manufacture special fasteners and numerous other machined components.

For CNC machined parts, our extensive plant portfolio includes 25 CNC turning centres for producing a massive range of CNC machined parts. We also have machining centres and lathes amongst other essential engineering machinery. Our custom-built facility in the UK is perfectly located for the careful production and rapid world wide delivery.

Our services and stock range includes high performance and exotic alloys. We maintain a secure and qualified stock of high performance and exotic alloys including carbon and alloys steels, stainless steels, copper alloys and bronzes, nickel alloys, inconel fasteners and polymers such as nylon, PTFE, acetal and peak.

The following alloys are available from stock: ASTM A193 B7, B7M, B16, B5, B6, B8, B8 Class 2 B8M, B8M Class 2, ASTM A320 L7, L7M, ASTM A453 660, ASTM A182 F51, F55, ASTM B637 N07718, N07080, ASME SA193 and ASME SA194, ASTM A449.

We also produce nuclear fasteners. For the nuclear power sector, we manufacture bolting from qualified materials under the provision of our nuclear endorsed ISO 9001 Quality Plan.

Our position in the nuclear supply chain is below the threshold requiring direct N-stamp approval. However two large and significant Western European Tier 4 engineering companies have vetted our quality systems according to both ASME III and RCC-M standards, under the provisions of their respective N-stamp. They have approved BNM as manufacturers of special and qualified fasteners for their nuclear engineering projects.

We also manufacture lid bolts/flask bolts for the handling of nuclear waste and decommissioning. Our nuclear customers benefit from high quality machining, total product confidence and the most rapid production and delivery service in the industry. We are able to manufacture and deliver nuclear accredited components within 24 hours.
