Grub Screws

Grub screws, also known as set screws, are a type of fastener that is typically used to secure an object within or against another one, without the need for a nut. These screws are headless, often fully threaded, and designed with an internal drive to be installed or tightened with a hex key or Allen wrench. Commonly, grub screws are employed to secure a pulley or gear to a shaft; they are inserted into a threaded hole in the object and tightened against the shaft to prevent relative motion. Unlike other screws, grub screws exert clamping force through their tip, which may be flat, cone-shaped, cupped, or knurled, depending on the required grip or compression against the mating part. Their application is widespread in engineering, manufacturing, and assembly work, where precise and reliable positioning is necessary.  Our range of grub screws are provided to steel class 45H in a range of sizes from M4 to M16.
