RS PRO Threading Tap, 1/4 → 28UNF Thread, UNF Standard, Hand Tap

Need a standard straight flute-type tap to use for your tapping applications? Choose this threading tap from our trusted RS PRO range for a durable solution. Its high-speed steel (HSS) material ensures resistance to high temperatures and wear, so it will hold up under harsh conditions. Its thread is of a unified fine (UNF) standard, meaning you can use it to make standardised threads. This product has been packed and handled in compliance with British (British Standard EN 61340-5-1:2007) and international (ANSI/ESD S20.20:2014) electrostatic control standards, so the risk of electrostatic discharge (ESD) is minimal. Tap threads like this one are commonly used to create the female portion of a mating pair, such as a nut, to hold a threaded bolt or other male fastener.
