- 1: Dimensional inspection is only applicable to threaded fasteners.
- 2: System 22 may be performed as a substitute for System 21 per ASME B1.3-2007, using the same sample size.
- 3: Chemical analysis must be performed using a quantitative method (Section 4.5.6.2)
- 4: Tensile testing is only applicable to threaded bolts, screws, nuts, and nutplates
- 5: Fasteners smaller than #10 or shorter than 2 times the diameter may not be capable of meeting this requirement.
