4-40-x1/4 UNC Imperial Stainless Steel Grub Screw 1/4 inch Length 40 TPI

Stainless Steel Cup Point Grub Screws: Grub screws are used to fix rotating parts to shafts. Cup point grub screws have a concave tip and are the most commonly used type of screw. They are headless screws which are threaded through a hole on the rotating part and tightened until the hexagon grub screw is flush with the shaft. This ensures the strength of the fixing while leaving no external extrusion. Grub screws are a small but extremely important part of many drive mechanisms and other machinery which uses moving and rotating parts.
Note: These set screws are designed for pressure loads and are not suitable for tensile- or shear loads.
