The ES-645L1 Slip Clutch Torque Screwdriver represents a versatile direct plug-in lever start torque driver, featuring a torque range of 13.2 – 39.6 in-lbs. This tool is equipped with a slip/cushion clutch mechanism that engages once the pre-set torque limit is achieved. This unique functionality imparts a subtle release of pressure on the screwdriver bit.
Designed for practical applications in mind, the ES-645L1 Slip Clutch Torque Screwdriver is particularly well-suited for tasks involving self-tapping screws and assembly applications where stringent torque control is not a primary requirement. The slip/cushion clutch ensures that the torque is applied up to the specified limit, preventing over-tightening and contributing to the longevity of the fasteners.
