Sturtevant Richmont Tapered and Flat Beam Torque Wrench, 16 in L, 3-51/64 in D, +/-2%, SAE

Part # 850247=8T
Log into view price
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.

• Incredibly durable design, the service life of these tools is frequently measured in decades
• These tools are based on a physical law (Hooke's Law) that does not change, exceptional accuracy retention permits extended calibration intervals and extremely low ownership cost
• Flat and tapered beam torque wrenches have a very low cost of ownership, they are virtually maintenance and repair-free, our beam wrenches have had extensive daily use in automobile production lines and are still within tolerance and fully operational after 25 years on the job
• Pivoted handle concentrates load at a precise point on the lever to assure torque accuracy
• The memory feature consists of pointers that follow a track on the scale and remain in place to indicate peak torque achieved
• The peak torque indicated on the scale is accurate even in destructive applications
• Bi-directional accuracy of +/-2% of indicated value from 20% to 100% of capacity
• Includes free certificate of calibration from our +/-0.25% indicated value accuracy/ISO/IEC 17025 accredited calibration laboratory
