7/16"-18 BSF HSS Bright Wizard® Spiral Point Machine Tap CT81328

HSS

BSW (British Standard Whitworth) is similar to UNC but differs in that the thread form for a BSW is 55° vs. the 60° for UNC

BSF (British Standard Fine) is a finer pitch series, also with a 55° degree thread form

BA (British Association) is a metric thread system devised by the British for small screws used in components with a thread form of 47 ½°

Spiral point forces the chips ahead of the tap - designed for through hole applications

Bright finish for tapping a wide range of materials but best suited for non-ferrous materials such as aluminum

The untreated surface on this tap gives lower friction and good chip flow for softer materials
