Break-Over Wrenches
Using break-over wrenches helps you support your quality control inspectors by empowering your workers to prevent assembly errors. Designed to accurately tighten diverse fasteners, break-over wrenches inform their operator when the right torque is reached by deflecting on their built-in hinge. As a result, you can reduce lost product or rework related to over- and under-torque conditions. Plus, their small size enables them to fit into areas with tight clearances. The end result is a boost in both productivity and project ROI. And with break-over wrenches, Mountz gives you the flexibility to switch out heads for tricky fasteners or to get more use out of your existing tools.
