Tools & Gear Taps & Dies Chrome Alloy Taps

• 1/8 x 28 BSPT Chrome Alloy Die Nut
• British Standard Pipe Taper (BSPT).
• Die nuts are commonly used when a button die is not suited due to work space restrictions and / or on site thread accessibility.
• They can be used as thread chasers to clean an existing thread.
• They can also be used to create a new male thread on non-ferrous metals and plastics.
• Chrome alloy dies are not suitable for creating precision, safety or critical threads.
• British Standard Pipe Taper (RC Series Pipe Taper) is based on the Whitworth thread form - a symmetrical V-thread with an angle of 55°.
• 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.
