Micrometer Adjustable Ratcheting Square Drive Torque Wrenches
SDR-Series
Applications
Micrometer Adjustable Ratcheting Square Drive torque wrenches are ideal for any application where:
- The fastener or fitting to be tightened can be engaged with a socket.
- The user changes from one torque to another often.
- A high amount of rotation or limited access requires ratcheting to achieve the desired torque.
- The ability to select the torque and lock it in rapidly is needed.
- Simplicity of operation is needed.
- Very high durability is needed.
These needs are common in small quantity assembly operations and many maintenance functions; the SDR-Series tools are superb for these types of applications.
Features and Characteristics
- Accuracy of +/- 4% of Indicated Value from 20% to 100% of rated capacity meets or exceeds requirements of ASME B107.300-2010 and ISO 6789.
- Ratchet design is exceptionally strong and durable.
- Fast adjustment – takes the fewest grip rotations of any tool to reach full scale.
- Simple thumbscrew mechanism locks to avoid changing torque setting accidentally.
- Neoprene rubber grip for cushioning and oil/chemical resistance.
- Includes FREE tabulated certification from our ISO/IEC 17025 Accredited Calibration Laboratory!
- Ratchet design is exceptionally strong and durable.
- All tools of 250 foot-pound (or equivalent) capacity and below come with a custom molded plastic case.
- The aluminum increment band is color-coded: black for inch-pounds, gold for foot-pounds, blue for Newton meter.
