Self Tapping Screws - Pozidrive Countersunk - Black

We stock two different point options for our pozidrive countersunk head self tapping screws, these are classified as Type AB and Type B.

Type AB has a sharp point on the end (sometimes called a gimlet point) and is commonly used with brittle materials and thin sheet metals. Type AB is the most common type of self tapper for general use.

Type B self tappers are flat and blunt on the end and are commonly used with light and heavy sheet metals (.050 to .200 thick), plastics, plywood and other similar materials. They are also safer to use where the presence of a sharp point is not advisable, i.e. where manual labour is used in large scale factory processing. Our type B self tappers with countersunk heads are only available in 4 size options.
