TAPPING SCREW

Product Feature :

Self-tapping screw have a wide range of tip and thread patterns, and are available with almost any possible screw head design. Common features are the screw thread covering the whole length of the screw from tip to head and a pronounced thread hard enough for the intended substrate, often case-hardened.  Not all self-tapping screw have a sharp tip.

The type B tip is blunt and intended for use with a pilot hole, often in sheet materials. The lack of a sharp tip is helpful for packaging and handling and in some applications may be helpful for reducing the clearance necessary on the reverse of a fastened panel or for making more thread available on a given length screw.

Sheet metal screw (sometimes called "sheet-metal self-tappers") these screws are a type of self-tapping screw despite the thread created in the sheet of metal being small. Pan-head  Self-tapping screw are common in electrical equipment while flatter-headed truss or flat countersunk headed self-tapping screw are more common in aviation applications.
