Self Tapping Screw Introduction:
Self tapping screws (also known as Sheet metal screws) are essentially screws that can tap their own hole as they are driven into it. They are used extensively in plastics and thin sheet metal such as aluminium. The size of the pilot hole, which is helpful but not mandatory, depends on the thickness of the material being screwed into. Tapping Screws work bets for thin sheet metal becasue the screw design, which is coarse and pitched at an angle, has the effect of pulling the metal tightly to the head. For applications involving thicker sheet metal over 1mm, a self drilling screw (also known as Tek screw) is advisable.
As for self tapping screws' head designs, ranging from Pozi, Phillips, Slotted, Torx (Hexalobular), Hex and Socket, Robertson are all available and important to suit specific applications. We have a large range of blunt point tappers which have been found to work very well in plastics as an alternative to plastite screws or our screws for plastics
The Type A and AB self-tapping screws are normal sheet metal screw with a fairly sharp point. Self-tapping is the ability of a screw to advance when turned while creating its own thread. They are commonly used with sheet metal and plastic components. This ability is created sometimes by creating a gap in the continuity of the thread on the screw. These edges can cut their own threads as the screw is driven in to the material, usually wood or plastic, as well as for metal. They function by having a cutting edge which drills away the material, making a hole for the screw to go into. They come in hex head (slotted or unslotted), hex washer, slotted and Phillips flat head, pan head, oval head, truss head and round head.
We also have pan square recess and flat square recess head. Torx pan head Type AB are also available. You can also find stainless steel and hardened steel, black oxide plated.
Type B are the blunt end style screw and they are available in flat head, pan head and truss head Phillips drive. We also have hex head washer, slotted and unslotted self-tapping.
We have the High-Low in Phillips with either flat or pan head. We also have available unslotted hex washer High-Low. We have this Type B industrial fastener available in stainless steel.
