Plastic “NO-MAR” gap and flushness gages, along with paint or dirt gages, were introduced to the auto assembly industry to reduce the scratches and dings caused by metal gages. These gages have eliminated the cost of repairs and repainting that have plagued auto makers for years. Available as “reference only” and “serialized and certified” to comply with ISO requirements. Gap gages are available in any combination ranging from 1/4mm through 6mm in 1/2mm increments.
