Plain limit gauges are used to inspect hole or shaft dimensions. Plug, ring and caliper gauges are commonly used. Plug gauges are usually used with holes 1 mm to 120 mm in nominal diameter. For holes 1 mm to 50 mm in nominal diameter, gauges with a GO end and a NO GO end attached to a handle (double-head type) are used. For holes exceeding 50 mm in nominal diameter, separate GO and NO GO gauges (single-head type) are used. NO GO gauges are provided with an identifying groove. A bleeder hole could be bored in these gauges upon veguests.
