Sturtevant Richmont

The four most important requirements of a torque wrench, accuracy, reliability, durability, and low ownership cost, are combined into these exceptional tools.
Accuracy is literally ground into the wrench. The special alloy steel beam is ground to a rate of deflection with the use of dead weights, rather than a dimensional tolerance. This process is time consuming and very labor intensive, but the result is a tool that remains accurate as long as the beam is intact and the pointer is on zero under no-load condition. The flat shape of the beam insures the wrench remains at a right angle to the fastener, reducing or eliminating side-loading error. This unique taper-grinding distributes stress evenly along the entire length of the beam, extending tool life indefinitely. With a minimum of moving parts, these tools are virtually repair and maintenance free.
Features
• Incredibly durable design – actual service life frequently measured in decades!
• Very low cost of ownership – exceptional accuracy retention permits extended calibration intervals, and they are virtually maintenance and repair free!
• Ideal for prevailing-torque and destructive testing applications.
• Low mass/low inertia design of pointers helps eliminate reading distortion.
• Memory feature consists of fingers which follow a track in the scale and remain in place to indicate maximum torque achieved.
• Peak torque indicated on scale is accurate, even on destructive testing applications.
• Pivoted handle concentrates load at precise point on lever to assure torque accuracy.
• Meets or exceeds ASME B107.300 – 2010 and ISO 6789.
• Accuracy of all flat beams is +/- 2% of indicated value from 20% to 100% of capacity, in both directions.
• Includes FREE calibration certificate from our ISO/IEC 17025 Accredited Laboratory.
