The 2-1/2" x 11 BSPF Taper HSS Tap is built for British Standard Pipe (G Series) parallel threads used mainly for mechanical coupling. Taper taps have a lead of eight threads and are used as a starting tap in difficult or high precision holes.
Pipe taps are much shorter than a similar size of regular hand tap while retaining the same design features. Manufactured from HSS for general-purpose use in medium tensile materials, this tap is suited to hand or general machine use for reliable BSPF thread starts.
