Sturtevant Richmont Roto-Torq PM

Capacity 70 / 170 / 400 cNm

Preset Torque Screwdriver

Sturtevant Richmont torque screwdriver for assembly operations and product specific kit and maintenance use. PM-Series Preset Torque Screwdrivers are ideal for any application where:

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


These needs are common in high-precision assembly operations and for maintenance tool kits for electronic and electro-mechanical products.


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