ASTM F2482

Full Name

ASTM F2482 – Standard Specification for Load-Indicating Externally Threaded Fasteners


This specification covers externally threaded bolts, studs, and cap screws, herein called fasteners, capable of indicating clamping forces up to yield strength during the tightening process or post installation residual tension, or both.

Load-indicating fasteners utilize a variety of sensor types to indicate fastener tension. This specification outlines the various types of load indication technologies available and defines their performance requirements.
