CNC Applications for Fasteners

Fasteners require precision and consistency, which is exactly what CNC machining provides. This guide covers the CNC applications for each fastener type.

Fastener Types That Can Be CNC Machined

Type of Fastener	Description	Common CNC Made Variants
Bolts	Threaded fasteners requiring a nut.	Hex bolts, carriage bolts, eye bolts
Screws	Threaded fasteners for pre-drilled holes or self threading.	Machine screws, set screws
Nuts	Internally threaded fasteners for bolts.	Hex nuts, flange nuts, cap nuts
Washers	Distribute load or prevent leakage.	Flat washers, spring washers
Rivets	Permanent mechanical fasteners.	Blind rivets, also known as pop rivets
Pins	Unthreaded fasteners for alignment or holding.	Dowel pins, taper pins
Anchors	Secure objects to concrete or masonry.	Concrete screws, wedge anchors
Studs	Threaded rods for securing from two sides.	Fully threaded studs, double ended studs
Retaining Rings	Hold components in place.	E-clips, external and internal retaining rings
Threaded Inserts	Provide a threaded hole in soft or brittle materials.	Helical inserts, key locking inserts

CNC machining offers precision and consistency, which makes it well suited to fasteners where high accuracy and tight tolerances are required.

CNC Fasteners FAQ

Why is CNC machining preferred for fastener production?

It offers precision, consistency and adaptability, so fasteners meet strict quality and performance standards across a run.

Can CNC machines produce custom fastener designs?

Yes. CNC machines can be programmed to produce bespoke fastener designs tailored to specific requirements or unique applications.

How does CNC ensure thread accuracy?

CNC machines follow precise digital instructions, so threads are cut or formed to exact specification and fit correctly.

Are there fasteners that cannot be CNC machined?

CNC machining is versatile, but certain fasteners with complex geometries or specific materials may require alternative manufacturing methods such as forging.
