Key Features of Alloy Steel made Plug Gauge

• Made out of quality grade high chrome alloy steel.
• Quality heat treated and hardened to 58-60 HRC to provide a high degree of wear resistance.
• Finely lapped to get maximum seating & surface finish.
• Sub-zero treated to take care of distortion for a long & stable life span.
• The plug gauges are used to measure holes and bores which are to be manufactured within a given tolerance.
• The plug gauges can be used to measure both `blind` holes and `through` holes, however, for `blind` holes a groove is provided to prevent air locks.
• The plug gauges are mainly used in areas of mass production where the bores [of components] are machined for interchangeable fit with male parts.
