Black, Self-Colour Steel Hex Socket Set M4 x 8mm Grub Screw

RS PRO range of hexagon grub screws features excellent capabilities within machine repair and fixing applications. Grub screws have no head (also known as headless or blind) and it is simply a threaded fastener to secure an object within another. They are generally used in tight areas where you do not want the head sticking out, or a little bit countersunk from the top of the material so nothing can hit it and interfere with the operation of the application. You tighten or undo them, using an Allen key. They can have various tip point types which include:
Cup point – concave tip, most commonly used
Flat point – used for frequent resetting or relocating, simple and cost-effective
Cone point – pointed tip, designed for a more permanent installation, highest holding capability due to the precise contact of the cone point
Half Dog point – the tip is cylindrical
