Carrying out proper maintenance and storage procedures will ensure longer life for thread gauges. Neglecting to clean thread gages after every use and inspecting them for burrs, grit and part chips may result in unnecessary wear and scratches on the gage flanks and major and minor diameters of thread gauges. Always check that the gage recalibration date is current.
To begin, be sure to review the current inventory of thread gages looking for visual signs of nicks, dents and scratches on gage members and handles. Evidence of this may suggest the gages are not being handled properly. Next train all personnel involved in the use of gages sound maintenance and storage techniques and protocols.
Protect thread gages from excessive heat, humidity, moisture and corrosive chemicals to extend gage life. After use, clean thread gauges using gage lubricant, and recoat with a thin-film rust preventative. An alternate method is to dip gauges in an easy-to-peel, oil-based waxed coating, and store properly. Once maintenance procedures have been carried out, store thread gauges in the appropriate plastic storage box, container, or cabinet to their specific type.
Gages should be periodically inspected and calibrated to assure accuracy. GO member thread gages tend to wear faster under normal use. NOGO gages will wear on the ends that receive the greatest usage. Inspect and recalibrate as necessary based on such factors as the amount of usage, part and gage material, tolerance, and quality procedures.
