Precision Steel Turned Parts Made in the UK
We manufacture precision steel turned parts and CNC-machined components to your exact drawings, tolerances and performance requirements. From shafts, spacers and bushes to threaded fittings, pins and specialist fasteners, our experienced UK team produces bespoke components in a wide range of mild, carbon and alloy steel grades.
What Are Steel Turned Parts?
Steel turned parts are precision-engineered components created by machining bar stock on CNC or manual lathes to produce tight tolerances and consistent finishes. These parts are commonly used in automotive, aerospace, construction, and industrial fastening applications — wherever strength, repeatability, and reliability are essential.
At Pattern Fasteners, we can manufacture steel turned parts in sizes ranging from 0.5mm to 250mm diameter, using both manual and CNC lathes for complete flexibility.
Steel Grades We Machine
We offer a broad selection of engineering steels to meet different strength, hardness, and machinability requirements, including:
- EN1A (230M07)Free cutting, ideal for precision turned parts
- EN3B (070M20)General purpose mild steel
- EN8 (080A40)Medium carbon, high strength
- EN16 / EN16T (605M36 / 605M36T)Toughened for shock resistance
- EN19 / EN19T (4140 / 709M40 / 709M40T)Excellent fatigue resistance
- EN24 / EN24T (817M40 / 817M40T)High tensile alloy steel for demanding applications
Each batch can be supplied with BS EN 10204 3.1 mill certificates, providing full chemical and mechanical analysis of the materials used.
Precision Manufacturing Capabilities
Our in-house production facility is equipped with the latest CNC turning centres and manual lathes, allowing us to produce bespoke components to even the most detailed specifications. We specialise in:
- Bar turning up to 250mm diameter
- Tolerances to ±0.01mm
- Prototypes through to full production runs
- Complex geometries and custom threads
- Repeatable accuracy across batches
Our advanced systems ensure that once we’ve programmed a component, we can replicate precise measurements time and time again, guaranteeing uniform quality.
Surface Finishes & Treatments
Enhance the performance and durability of your steel turned parts with a range of optional surface treatments:
- Zinc or nickel plating
- Black oxide coating
- Passivation and polishing
- Case hardening and heat treatment
