Description

1/4″ x 19 BSPF Bottoming HSS TAP – Goliath
HSS Bright Finish BSPF Hand and Machine Bottoming Tap.
Pipe taps are much shorter than a similar size of regular hand tap, but the design features are the same.
Goliath HSS taps provide a high hardness to toughness ratio, compressive and tensile strength, good abrasion resistance and resistance to micro-chipping, ensuring a long tool life.
British Standard Pipe – G Series (BSPF) is a pipe thread which is used mainly for mechanical coupling.
The angle of thread is mainly 55º however for the US method some threads have a 60º angle. It is specified according to JIS and ISO R228.
Bottoming Taps have a lead of two threads and are used to ensure minimum thread run-out when tapping to the bottom of a blind hole.
Bottoming Taps are typically preceded by the use of a Taper or Intermediate Tap.
Manufactured from HSS this general purpose tap is designed for use in medium tensile materials and is for hand or general machine use.
