Grub Screw M2.5 x 4mm (20 pieces)

Description A grub screw or set screw is generally used to secure an item against another item, without the use of a nut.  This is important, because the ability to secure without a nut makes the grub screw very versatile, and means that a grub screw can be used in applications that require a very small and unobtrusive fixing. The threading travels the entire length of the grub screw, ensuring a firm and effective grip.
