Ratcheting Square Drive Micrometer Adjustable Torque Wrench
SR: "Customers tell us they love these wrenches because they are accurate, reliable, and durable. In designing the new handle we kept all the things that our customers love and added the Knurl Grip aluminum handle. Strong, lightweight, rugged, ergonomic, this handle truly lets you get a grip on torque."
In sync with the Sturtevant Richmont approach to customers you can buy just a retrofit kit and replace the handle yourself or you can buy new wrenches with the new handle already in place. Either way the best accuracy, reliability, and durability is within your grasp.
Micrometer Adjustable Ratcheting Square Drive torque wrenches are ideal for any application where:
These needs are common in small quantity assembly operations and many maintenance functions; the SDR-Series tools are superb for these types of applications.
