The preset wrench ensures that the correct torque value is consistently applied to each fastener. It's designed to have a fixed head permanently attached. Breaks over upon reaching preset torque. Improves the fastening process by reducing the risk of both over and under-tightening. Delivers repeatability, traceability, and precision for all tightening applications. Six different colored aluminum handles allow for color-coding of specific torque values in production areas. No external adjustment scale must be preset using a torque analyzer Designed and manufactured to meet or exceed the accuracy and repeatability requirements of ISO 6789: 2017 (+/- 6% of setting).
