Threaded Insert Taps

Screw thread insert taps (STI taps) operate in the same manner as “standard” taps, but produce an oversized thread specifically for threaded inserts. During insert installation, the threads cut by an STI tap form the insert into the desired thread size. STI taps are ideal for tapping holes in softer metals that require a strong threaded insert. STI taps are manufactured from high speed steel (HSS) for superior durability. We offer STI taps in a wide range of inch, metric, and spark plug sizes to meet your unique requirements.
