Description
Irwin 8-32 NC Taper Bottom Bulk HCS Machine Screw Tap (1224ZR) is a precision threading tool crafted for creating standard 8-32 NC threads. This tap is an essential component for any toolbox, suitable for professionals and DIY enthusiasts engaged in a variety of repair and fabrication tasks. Made from high carbon steel, it provides a solid balance of hardness and toughness, making it effective for hand-threading work in a wide range of materials. Its design focuses on practicality and efficiency, with a bottoming chamfer that allows it to create threads all the way to the base of a blind hole, a task where other tap types fall short. The four straight flutes are a key feature, engineered to provide rapid chip removal and prevent material buildup, which is critical for producing clean and accurate threads.
