• BSW - British Standard Whitworth
• The angle of thread is 55 ° as opposed to 60 ° in Metric and Unified threads.
• This thread form was developed by Sir Joseph Whitworth in 1841. The thread form has rounded roots and crests and is specified in BS84:1956.
• Taper taps have a lead of eight threads and are used as a starting tap in difficult or high precision holes.
• Intermediate taps have a lead of four threads and are used in most general purpose applications to cut a thread true to a pre-drilled pilot hole.
• 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.
