Grooving

Grooving Services for Fasteners & Precision Components

Pattern Fasteners provides grooving services for fasteners, turned parts and precision-engineered components as part of our wider modifying and secondary machining capabilities.

Grooving is used to machine a recessed channel or profile into a component for locating, retaining, sealing, clearance or assembly purposes.

We can produce grooves in both newly manufactured parts and suitable existing components, depending on the material, dimensions and application requirements.

What Is Grooving?

Grooving is a machining process used to create a controlled recess in the surface of a component.

The groove may be used to accommodate:

• Circlips

• O-rings

• Seals

• Retaining rings

• Clips

• Mating components

• Lubrication features

• Clearance requirements

Grooves can be machined externally or internally depending on the component design.

External Grooving

External grooves are machined into the outside diameter of a component.

They are commonly used on:

• Shafts

• Pins

• Studs

• Bolts

• Collars

• Spindles

• Rollers

• Turned components

External grooves may be used for retention, positioning or to accept another mechanical feature within the assembly.

Internal Grooving

Internal grooves can be machined inside bores or tubular components where a recessed feature is required.

These may be used for:

• Internal retaining rings

• Seals

• O-rings

• Component location

• Clearance

The achievable groove dimensions will depend on bore size, depth, access and material.

Circlip & Retaining Ring Grooves

Grooves can be produced to accept circlips and retaining rings where a component needs to be held in position along a shaft or inside a bore.

The groove width, diameter and position can be machined to suit the specified retaining component and assembly requirements.

O-Ring & Seal Grooves

Grooves can also be produced for O-rings and other sealing components.

These require careful control of groove dimensions to ensure the seal performs correctly within the completed assembly.

Where sealing performance is critical, groove geometry should be specified on the engineering drawing.

Custom & Special Grooves

Pattern Fasteners can machine grooves with customer-specific dimensions and profiles, including:

• Narrow grooves

• Wide grooves

• Deep grooves

• Shallow grooves

• Multiple grooves

• Stepped profiles

• Undercuts

• Special-purpose recesses

Grooving can also be combined with turning, threading, drilling, tapping and other machining operations.

Materials Suitable for Grooving

Grooves can be machined into a wide range of engineering materials, including:

• Carbon steels

• Alloy steels

• Stainless steels

• Aluminium

• Brass

• Bronze

• Copper and copper alloys

• Nickel alloys

• Specialist engineering materials

The tooling and machining method will depend on the material and required groove geometry.

Grooving to Drawing

Where grooving forms part of a bespoke component design, Pattern Fasteners can work directly from your engineering drawing, dimensional specification or physical sample.

Requirements can include:

• Groove width

• Groove depth

• Groove diameter

• Groove position

• Number of grooves

• Internal or external configuration

• Tolerance

• Surface finish

Grooving for Component Modification

Grooving can often be added to an existing or semi-finished component where a standard part requires an additional retaining, sealing or locating feature.

This can be a practical alternative to manufacturing an entirely new component.

UK Grooving Services

Pattern Fasteners provides precision machining and component modification services from our West Midlands facility.

Whether you require a single retaining groove or multiple machined profiles on a more complex component, we can produce parts to drawing or modify suitable existing components.
