Frequently Asked Questions (FAQs)
1. What are pin gauges for?
Pin gauges are used to measure and inspect the diameter of small holes. They are designed as precise pins of fixed sizes and can also be used as test bars for measuring geometric deviations.
2. How do I choose a pin gauge?
When choosing a pin gauge, refer to the size of the diameter specified on the drawing of the measured parts. Within the diameter range, start with the smallest gauge. For example, if the round hole diameter is 3.00 ± 0.005mm, begin with a 2.950 pin gauge and gradually test larger sizes.
3. How accurate is a pin gauge?
Pin gauges have a high level of accuracy. They have an inch tolerance of .0002” and a metric tolerance of .005mm. This level of precision makes them suitable for applications that require both accuracy and efficiency.
