(16 Pack) 16 X M3x8 High Tensile Allen Key Socket Cup Point Grub Screws. Free uk delivery. Grub screw sizes and shapes also vary considerably depending on for what they are used. There are six different end shapes to a grub screw, including the flat end for general purpose use and which is often found in toy applications, such as in remote-controlled car parts, and the domed point end which is stronger than the flat end design and has a slightly pointed tip that can be used to apply pressure to a part opposite the head of the screw. The cone point tip is used to apply force to soft materials or to fit into a depression in metal facing the end of the grub screw, and the cup point does the same thing only with greater force. The knurled point is shaped the same as a cup point end except that the protruding cup of metal on the end of the screw is ridged with parallel serrations that can be gripped by other equipment or parts. The dog point grub screw has a rivet-like cylindrical head at the end which can be used as a pivot shaft for equipment such as metal or plastic parts that need to rotate around it.
