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

Suitable for various steels (up to 32Rc) and stainless steel

Ferrous oxide surface treatment increases wear resistance, improves chip flow and reduces chip welding

The ferrous oxide surface treatment also enables the tap to absorb the lubricant / cutting fluid
