Standard Height Gauge Contact Points
Precision Ground
Standard and Special Applications
5691 Setting Standards are hardened and precision ground to the API accurate requirement of ± 0.0001” between adjacent notches and ± 0.0002” between nonadjacent notches. Standards for tapered threads are compensated for error in measuring lead parallel to the taper cone instead of parallel to the pipe axis.
Before using the lead gauge, it should be zeroed out with an Allen Lead Gauge Setting Standard (Template). The dial indicator should read zero when applied to the Setting Standard. If it does not, the sliding beam lock screw should be loosened, the gauge adjusted to zero using eh adjusting screw, and the lock screw tightened.
