Grub Screw

Precision-Manufactured Grub Screws

Pattern Fasteners manufactures standard, special and custom grub screws for a wide range of industrial, mechanical and engineering applications.

Also known as set screws, grub screws are typically used to secure one component within another without requiring a protruding screw head. They can be manufactured to customer drawings, samples or bespoke specifications, with close control over threads, lengths, drive types, point styles, materials and finishes.

Our manufacturing capabilities support small batches, specialist requirements and repeat production quantities.

Custom and Special Grub Screws

We manufacture grub screws for applications where standard off-the-shelf components are unsuitable.

Options may include:

• Metric and imperial thread forms

• Standard and non-standard diameters

• Bespoke lengths

• Socket, slotted and specialist drive types

• Cup, cone, flat, dog and other point styles

• Fully threaded designs

• Specialist material grades

• Heat treatment and hardness requirements

• Protective and decorative finishes

• Drilling and other secondary modifications

Grub Screws Made to Your Specification

The correct design will depend on how the grub screw is installed, the material it contacts and the holding performance required.

Our experienced team can work from your technical drawing, sample or individual specification to determine the most suitable thread form, point style, material and finish.

Careful control throughout manufacture helps ensure consistent dimensions, reliable engagement and dependable performance in service.

Materials and Finishes

Custom grub screws can be manufactured in a range of materials and supplied with finishes selected to suit the application and operating environment.

Requirements may include carbon steel, alloy steel, stainless steel and non-ferrous materials, together with specified hardness, heat treatment or corrosion-resistant coatings.

Available finishes include bright zinc plating, tin plating, chemical black, chrome and phosphate coatings.
