Screw Thread Insert (STI) Taps

0 products

STI taps are specialized tools designed to create oversized threads within a hole, facilitating the installation of helical-coil screw thread inserts. These inserts enhance thread strength by evenly distributing load across the thread length, especially when standard-sized fasteners are used. Straight-flute STI taps channel chips into their flutes without removing them during the threading process. In contrast, spiral-flute STI taps efficiently extract chips from the hole, minimizing the risk of chip accumulation. Spiral-point STI taps advance chips ahead of the tap, effectively clearing them from the hole to prevent flute clogging. Unlike traditional cutting taps, thread-forming taps generate superior threads without producing chips, offering cleaner, more durable, and precise results. Additionally, pipe STI taps are tailored for creating internal threads in pipe and fitting applications, adhering to specific standards and sizes.
