| M20 x 1.5 HSS STI Bottoming Tap
Screw Thread Insert (STI) Taps are used specifically to create threads
for Helical Thread Inserts. STI Taps are oversized so the thread
produced will accept a Helical Wire Insert of the same nominal size and
pitch - meaning the hole created by the Tap goes back to the original
dimension allowing the original fastener to be used.
- For use with: Helical Screw Thread Inserts
- Use with Internal Thread Size: M20 x 1.5
- Material: HSS (High Speed Steel)
- Compatible with: Helicoil, Recoil, Perma-Coil, Powercoil or any other standard Helical Screw Thread Inserts
"Bottoming" style Tap has a continuous edge with almost no taper which

stainless steel, and plastic. Proudly made in the USA.Tap also available in the following styles: Plug, Spiral Point, Spiral Flute & Spiral Flute Bottoming. Please call for quote and availability.
