Sturtevant Richmont Roto-Torq PM Preset Torque Screwdriver

Capacity 6 / 15 / 36 lbf·in

Cam-Over Preset Torque Screwdriver

Customers around the world hail the SR Torque Screwdriver as the absolute best in the world. Why? Let's start at the beginning.

Richmont company founder Frank Livermont (former Lockheed Martin engineer) invented the torque screwdriver. Early on, Cleco wanted to buy the patent. Livermont refused to sell the patent. So Cleco made Livermont an offer he couldn't refuse. They bought the company. Cleco made the limited slip clutch famous; they owe that notoriety to the inventive Frank Livermont.

The design hasn't changed much since 1944 when Livermont patented the torque screwdriver. Why hasn't it changed? Because Livermont got it right the first time!

Now, it’s a classic.

The Roto-Torq PM series preset torque screwdrivers for assembly operations and product specific kit and maintenance use 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.
