Description
Allen Gauge & Tool Co.
5691-A, Lead Set Standard, all 8 Round & 10 Round, 3/4″ TPF for casing, tubing & drill pipe
Lead Setting Standard
Allen Gauge & Tool Co. setting standards are hardened and precision ground to the API accuracy 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 the adjusting screw, and the lock screw tightened.
Setting standards for specific threads can be made.
Please furnish complete thread data and prints.
ISO 17025:2017 Accredited Laboratory, as an OEM we offer professional calibration services for all the gages that we manufacture.
*TPF = Taper Per Foot, TPI = Threads Per Inch
