Set screw is a kind of screw specially used for fixing the relative position of machine parts. When in use, screw the set screw into the screw hole of the part to be fixed, and press the end of the screw on the surface of another part, even if the former machine is fixed on the latter one. Slotted and inner hexagon set screws are used on parts where the head is not allowed to be exposed, and square head set screws are used on parts where the head is allowed to be exposed .

Partial thread screw is one of the non-standard screws, the general tail thread and no thread near the head. When the screw enters the preset hole, the chip scraped out by the tail thread can be discharged better, and less effort.When producing long screw, full screw is more expensive than partial thread screw, this price difference still can increase with screw length and more obvious. Sealing screw, commonly used in electricity meter, water meter, gas meter and tanker, etc. Phillips slotted Combo: Use either a Phillips screwdriver or a flat-head screwdriver.
