Frequently Asked Questions:
Q. What is the difference between plus and minus pin gauges?
A. A minus pin gauge set consists of pins with a tolerance less than the goal size, allowing the pin to fit inside the target dimension. Whereas a bore at the goal dimension is impossible with a plus pin gauge set which has pins with a defined tolerance above the target dimension.
Q. What does class X tolerance mean?
A. It means that the gauge has an inch tolerance of 0.00004 inches and a Metric tolerance of 0.001 mm.
Q. What is the difference between Go and No-Go gauges?
A. While No-Go gauges measure the higher tolerance, Go gauges measure the lower.
