1. Plum blossom depth gauge: It is used to detect the depth of the plum blossom groove head of the screw and judge whether it meets the requirements of passing and stopping. II. Plum-blossom groove inspection fixture template: * * Go/No-go * * logic is adopted to judge whether the parts are qualified through physical insertion/fitting. III. Plum Blossom Go-No Go Gauge: The final gauge is of single-end structure and is used for finished product inspection. 4. Inspection tool for meter character batch head: the M point shall be accurately placed between the lower step and the upper step for inspection. 5. Nut depth gauge: It is subdivided into cross nut inspection gauge, cross nut inspection gauge, cross nut depth gauge, hexagon and dodecagon go/no-go gauge and depth gauge. 6. E and M series ring gauges: All gauges are subject to heat treatment and thermal stability, and the surface is subject to wear-resistant treatment. 7. Ball head depth gauge, pentagonal go/no-go gauge, inner hexagonal inspection ring gauge: widely used in electrical appliances, automobiles, bridges, high-speed railways, aviation, construction, electric power, energy, steel structure, engineering machinery and other fields. 8. Length gauge and thickness gauge: by means of mechanical structures such as vernier caliper and micrometer, the length is converted into mechanical displacement through direct contact with the object to be measured, and the reading is carried out through the scale or dial. Screw thickness gauge, thread depth gauge: a variety of models, specifications, to meet the needs of industrial precision testing.
