    • Grub Screws

    Our range of grub screws (also known as set screws) includes a wide selection of high-quality fasteners in both metric and imperial thread forms. Suitable for fixing pulleys, collars, couplings and shafts without protruding heads, these screws provide secure clamping in mechanical assemblies, engineering applications and general workshop use.

    Available in a variety of sizes, materials and head types, our grub screws offer reliable thread engagement and holding power where flush fitting is required. Choose from hex socket, slotted and cup point grub screws in materials such as zinc plated steel, A2 stainless and A4 stainless to suit your specific application.

    Browse the range below and use filters to refine by thread size, length and material to find the correct grub screw for your task.
