Custom CNC Bolts
Custom CNC bolts machined to your thread pattern, length and head design, with surface treatments to suit the application.
- VariantsHex bolts, carriage bolts, eye bolts and custom head designs
- MaterialsSteel, stainless steel, aluminum, brass and titanium
- ThreadCustom thread patterns and pitches machined to specification
- FinishesPolishing, anti corrosion coatings, electroplating and other treatments
- InspectionThread gages, ring gages, first piece and final inspection
Category: Fasteners CNC
Product Overview
CNC bolts are threaded fasteners machined rather than formed, which allows non standard threads, unusual head geometry and tight tolerances that rolled production fasteners cannot offer. With advanced machinery, skilled staff and a commitment to quality, we make sure every bolt meets international standards.
Key Benefits
Tailored Designs
Whether you need a specific thread pattern, length or head design, we can machine it.
Surface Treatments
From polishing to anti corrosion coatings, treatments enhance both longevity and appearance.
Bulk Orders
Our infrastructure handles large orders without compromising quality or delivery timelines.
Thread Accuracy
Threads are cut to digital specification and verified with thread gages.
Application Scenarios and Who It Is For
- Machinery and equipment assembly
- Automotive and vehicle assemblies
- Structural and mounting applications
- Replacement fasteners for legacy equipment
- Applications requiring non standard thread or head geometry
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
Can you match a legacy bolt I can no longer buy?
Yes. Send a sample or a drawing with the thread specification and we will machine a replacement.
Which material for a corrosion exposed bolt?
Stainless steel for general corrosion resistance, or a coated alloy steel where strength matters more. Tell us the load and environment and we will advise.
How are threads verified?
With go and no-go thread gages, as part of first piece and final inspection.
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.
