CNC Fasteners
Custom CNC Fasteners
Fasteners machined on CNC equipment rather than selected from a standard catalogue. When a bolt, nut or screw has to match a non standard thread, head form, length or material, a machined fastener solves what a catalogue part cannot.
Product Overview
Fasteners machined on CNC equipment rather than selected from a standard catalogue. When a bolt, nut or screw has to match a non standard thread, head form, length or material, a machined fastener solves what a catalogue part cannot. Designs are produced to the customer's drawing, with the material and finish agreed before production.
Key Benefits
- Head form, thread and length made to your drawing instead of forcing a design around a catalogue part
- Materials chosen for the application rather than by what is in stock
- Consistent production once the process route is fixed at sampling
- Suitable for both prototype quantities and repeat batches
- One supplier for fasteners alongside machined and fabricated parts
Problems It Solves
- Designs compromised to suit an available catalogue fastener
- Obsolete fasteners with no remaining supply
- Mixed sources giving inconsistent thread fit between batches
- Long lead times on special fasteners from stockists
Where It Is Used
Applications And Buyers
Application Scenarios
- Equipment assemblies where a standard fastener does not fit
- Replacement fasteners for machines whose original parts are obsolete
- Prototype builds needing a special fastener quickly
- Products where fastener appearance is part of the design
Who It Is For
- Machine builders with non standard joints
- Maintenance teams supporting obsolete equipment
- Product designers needing a specific head or drive form
- Buyers consolidating machined parts and fasteners on one order
Technical Features And Specifications
Technical Features
- CNC machined rather than cold formed, so small quantities are practical
- Custom thread form, pitch, head shape and drive
- Material selected for strength, corrosion resistance or appearance
- Produced to customer drawing
- Finish applied to the agreed specification

How It Is Made And Checked
Materials Process And Quality Control
Manufacturing Process
- CNC turning
- Thread machining
- Finishing
Quality Control
- Specification agreed in writing before production starts
- First article or sample approved against the agreed specification
- Goods inspected and photographed at the factory before loading
- Inspection report sent to you before the container sails
Customisation Options
What Can Be Varied
- Thread form, pitch and tolerance class to your drawing
- Head shape and drive type
- Material grade agreed in writing before production
- Surface finish and coating
- Marking or identification where required
Compared With The Alternatives
| Standard catalogue fasteners | Catalogue parts are cheaper wherever they fit; machined fasteners are for the joints where they do not. |
|---|---|
| Cold formed special fasteners | Cold forming is cheaper at high volume but needs tooling; machining is the practical route for lower quantities and quick changes. |
Use Guide
- Send a drawing with thread specification and tolerance class stated
- Confirm the material grade and any required strength class
- Specify the finish, since it affects thread fit
- Approve a first article before releasing a production batch
Questions
Questions Buyers Ask About This Product
Can you make fasteners to a non standard thread?
Yes. Thread form, pitch and length are machined to your drawing, which is the main reason to choose a machined fastener.
What quantities do you accept?
From prototype quantities up to repeat production batches.
Which materials are available?
The material is chosen for the application and confirmed in writing before production. Tell us the strength, corrosion and appearance requirements.
Do you supply finished or plain fasteners?
Either. Finish is specified with the order, and we allow for its effect on thread fit.
Can you copy an obsolete fastener?
Yes, from a sample. We measure it, produce a drawing for approval and machine from that.
