Product Overview
CNC screws are precision engineered components manufactured using computer numerical control machinery. They are known for tight tolerances, high quality finishes and durability. Unlike traditional screws, CNC screws are produced to exact digital specification, which gives consistent quality from the first piece to the last.
Our screw range covers various materials, sizes and finishes, so specialised applications are served rather than approximated with the nearest standard item.
Key Benefits
Tight Tolerances
Machined to exact digital specification rather than formed to a general standard.
High Quality Finishes
Surface treatments chosen for appearance, corrosion resistance or friction.
Material Range
Screws made from various materials to suit the assembly and environment.
Durability
Precision machining reduces stress raisers that shorten fastener life.
Application Scenarios and Who It Is For
- Machine screws for equipment assembly
- Set screws for shaft and collar fixing
- Instrument and electronics assemblies
- Automotive and machinery components
- Applications where standard screws do not fit
If your application is not listed, send the drawing anyway. Most of our work arrives as a part nobody else wanted to quote.

Manufacturing Process and Quality Control
Drawing Review
Our engineers review manufacturability, confirm tolerances and raise anything in the drawing that would cause a problem before production starts.
Sample Approval
Free samples are offered prior to mass production, with first piece inspection recorded against your drawing.
Production Control
In-process inspection at a set frequency during the run, using the coordinate measuring machine and gauges in our inspection room.
Surface Treatment
Anodizing, sand blasting, polishing, electroplating and powder coating applied in house after deburring and cleaning.
Final Inspection
The finished lot is checked against the drawing before packing, with certification issued for the stages you require.
Packing and Delivery
Protective packing appropriate to the part, dispatched within the agreed delivery date.
Customization Options
- Material — specify a grade from our catalog, or describe the function and our engineers will recommend one.
- Tolerance — standard machining tolerance is 0.005 to 0.01 mm; tighter callouts are discussed at quotation.
- Surface finish — anodized, sand blasted, polished, electroplated, powder coated or as machined.
- Marking — laser engraving and CNC engraving for part numbers and logos.
- Quantity — from a single prototype through to long production contracts.
- Certification — certification provided at each stage on request.

Product FAQ
What makes a CNC screw different from a standard screw?
Tolerance and consistency. A CNC screw is machined to your specification, so head geometry, thread and length are exactly what your assembly needs.
Can you produce a very small quantity?
Yes, though per piece cost is higher at low quantities because setup is shared over fewer parts.
Do you supply certification with fasteners?
We provide certification at each stage on request. Tell us at quotation what your programme requires.
How do I order this part?
Do you offer free samples?
Yes, free samples are offered prior to mass production so you can confirm the part before committing to a run.
