Features:

• 1" x 11 BSPT Bottoming HSS Tap
• HSS BSPT Bottoming Hand and Machine Tap.
• British Standard Pipe Taper (RC Series Pipe Taper) is based on the Whitworth thread form - a symmetrical V-thread with an angle of 55º.
• BSPT has been widely adopted internationally for interconnecting and sealing pipe ends by mating an external (male) with an internal (female) thread.
• The thread diameter increases along the length of the thread allowing the coupled pipes to form a seal when torqued as the flanks of the threads compress against each other.
• The taper is "1 to 16", meaning that for each 16 mm increase in the distance from the end, the diameter increases by 1 mm.
• Manufactured from HSS this general purpose tap is designed for use in medium tensile materials and is for hand or general machine use.
