Sturtevant Richmont Roto-Torq CAL Adjustable Torque Screwdriver

Micrometer Adjustable Torque Screwdriver with Dual Scale

A classic! Sturtevant Richmont's CAL 36/4, with its' dual English/Metric scale, amazing durability, and ease of use has been an industry leader for decades – for good reasons. The CAL line of torque screwdrivers is first choice for many electronic and small-component manufacturers. The SR CAL-Series Adjustable Torque Screwdrivers are ideal for any application where:

• High repeatability for low torque is needed,
• Excellent durability and versatility are needed.

These needs are common in high-precision operations such as electronics and electro-mechanical repair. To operate, simply dial torque setting and insert bit. The Micrometer scale on the shaft is marked in dual incrementation (lbf·in and N·m on CAL 36/4, kgf·cm on CAL 40).

The operator cannot overtorque. A clutch releases automatically when desired torque has been achieved. The anti-backlash design enhances the repeatability. CAL torque screwdrivers are incredibly durable. Many owners have experienced a service life of 10+ years.
