Ojiyas limit gauges for screw threads are provided in the same class as the standard screws. The GO and NO-GO limit gauges are used to check the accuracy of the threads. The workpieces are inspected to ensure they are within the upper and lower limit of deviations and tolerances.

Ojiyas screw threads limit gauges are used corresponding to the various screws such as metric screw, bicycle screw, unified screw, sewing machine screw, etc. The limit gauges are segmented into ISO-based JIS and conventional JIS (for inspection and production use). According to JIS, outside diameter of the male screws are basically measured using plain ring gauge or snap gauge and inside diameter of female screws are measured using plain plug gauge. By using such gauges, the complex element of the screw can be inspected easily and quickly. Therefore, such gauges are effective in controlling the quality of the workpieces in mass-production line.
