Spiral-Point STI Taps
Available0 products
Spiral-point STI (screw-thread insert) taps have straight flutes with a spiral point that pushes chips in front of the tap as it moves into a hole and out the other side, eventually forcing the chips out of the hole. They are used for creating oversize internal threads in through holes so a helical-coil screw-thread insert can be installed in the hole. The insert distributes the load across the length of the threads and improves the threads' strength when a fastener with a standard screw thread size is installed in the hole.
