Features Ratcheting non-insulated micrometer torque wrenches have a gear mechanism on the head that allows the wrench to rotate freely in one direction without removing the wrench head from the fastener and repositioning the wrench. They have a fixed, non-flex head with ratcheting action that allows torque to be applied to fasteners in tight spaces.
