Insize Fine Thread Plug Gauge, Go and No Go, 6H Class, ISO 1502 Standard and Size M36 x 1.5 mm, 4139-36R is produced from hardened, wear-resistant steel to maintain dimensional stability and long-term accuracy even under repeated inspection cycles. Clear Go and No Go markings reduce operator error and improve inspection efficiency on shop floors and in metrology labs. This gauge is widely used in automotive, aerospace, tooling, and general engineering industries where fine-pitch threads are critical for performance and safety. Its robust construction, precision grinding, and adherence to international standards make it a dependable solution for routine inspection, final quality control, and process validation.
