Applications

Tapered and Flat Beam torque wrenches are excellent choices for any application where:

  • The ability to visually confirm that the tool is correct before each use is important.
  • The application is such that the user can see the faceplate of the tool.
  • Greater accuracy than that provided by clicker torque wrenches is desired.
  • It is important to know torque variation during rundown, as with prevailing torque nuts.
  • There is a destructive nature to the application.
  • The peak torque is of importance.

These needs are common in aircraft assembly and maintenance operations, fastener testing (in-process/final/receivinging inspection) for prevailing torque nuts, and assembly compliance testing for products with rotating components. For these and similar operations, Flat Beam and Tapered Beam torque wrenches are often the best tool for the job.

Features and Characteristics

  • 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!
  • Pivoted handle concentrates load at a precise point on lever to assure torque accuracy.
  • Memory feature consists of pointers that follow a track on the scale and remain in place to indicate peak torque achieved.
  • Peak torque indicated on scale is accurate even in destructive applications.
  • Bi-directional accuracy of +/- 2% of Indicated Value from 20% to 100% of capacity meets or exceeds requirements of ASME B107.300-2010 and ISO 6789.
  • Includes FREE tabulated certification from our ISO/IEC 17025 Accredited Calibration Laboratory!
