About this item:
- 7/8" x 14 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 55° however for the US method some threads have a 60° 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.
