The Wera 844 Hex Shank Thread Tap in M8 Taper configuration is built for cutting robust metric M8 threads, making it ideal for heavier-duty fastening applications across engineering, fabrication, and construction trades. M8 is a popular thread size for structural and mechanical assemblies, and this tap bit delivers the precision and durability those applications demand. The ¼” hexagonal shaft engages securely with DIN ISO 1173-D 6.3 compatible holders, providing excellent torque transfer even when working in tougher materials. Wera’s finely-tuned material elasticity helps the tap resist breakage under increased load, while the precision-engineered flute geometry ensures efficient chip evacuation and a controlled, accurate return stroke throughout the threading process.
