# Introduction The Smooth Plug Gauge is a critical tool in modern manufacturing, designed to measure the inner dimensions of workpieces with exceptional accuracy. As part of a comprehensive gauge series offered by Storaen (Cangzhou) International Trading Co. , this product exemplifies precision engineering and adaptability to diverse industrial needs. Whether in automotive, aerospace, or general manufacturing, the Smooth Plug Gauge ensures compliance with international standards such as GB1957-81 and DIN7162 , making it indispensable for quality control processes. # Product Overview The Smooth Plug Gauge is a precision instrument used to verify the internal dimensions of machined components. It is manufactured in two primary configurations: the through end (minimum limit dimension) and the stop end (maximum limit dimension). The through end must pass through the workpiece, while the stop end must not, ensuring that the measured part meets specified tolerances. This dual-function design makes it ideal for applications requiring high accuracy, such as precision machining and custom gauge manufacturing . # Technical Specifications The product adheres to strict standards, with accuracy levels ranging from H6 to H12 , depending on the application. The following table outlines key dimensions in millimeters: 1.8 16 34 62 120 2.0 17 35 65 125 2.5 18 36 68 130 3.0 19 37 70 135 3.5 20 38 72 150 4.0 21 39 75 165 4.5 22 40 80 180 5.0 23 42 82 200 6.0 24 44 85 7.0 25 45 88 8.0 26 46 90 9.0 27 47 92 10.0 28 48 95 11.0 29 50 98 12.0 30 52 100 13.0 31 55 105 14.0 32 58 110 15.0 33 60 115 Note: Non-standard dimensions and specialized gauges, such as tapering gauges and precision ring gauges , can be customized to meet specific requirements. # Key Features and Advantages High Accuracy: Compliant with GB1957-81 and DIN7162 standards, ensuring reliable measurements across industries.
