VERMONT GAGE 911170500 Pin Gage, Class ZZ, Go, BG, 0.705 Inch Size

Vermont 911170500 pin gauge is used to perform Go tolerance tests on bore holes with inch-sized threads. The gauge indicates that the hole is within the permitted tolerance if it fits into the bore or hole.

Features:

• Vermont 911170500 pin gage is designed for quick and accurate measurements, checking locations and calculating the distances between holes & gauge slot widths.
• It features solid steel construction with black oxide finish that exhibits evidence of wear to let users know when the gauge might need to be replaced.
• This Class ZZ Go Plus unit has 10 microinch finish and heat-treated RC 60/65 hardness.

Standards and Approvals:

• ISO 17025
• NIST

Frequently Asked Questions:

Q. What is the difference between pin gauges and ring gauges?

A. The pin gauges are used to measure hole sizes and calculate distances between holes, while the ring gauges are used as bore gauges to measure the external diameter of the manufactured parts.

Q. How do you use a Go pin gauge?

A. If the go gauge fits within the component, it means that the mate component won't have too much material and will likewise fit, assuring correct assembly. The Go gauge is put into a part's hole to examine the size of the hole. The hole is deemed to be over its low limit if the gauge can be inserted into it.

Q. At what conditions gauging should be done?

A. In order to minimise the impact on the inspection, gauging should be done under ideal circumstances, such as clean parts and controlled temperatures. Another aspect to take into account is work tolerance, in which a gauge wear allowance could be applied. In this instance, the diameter of the Go gauge is increased to account for wear. It is important to specify tolerances such that the overall gauge tolerance does not go beyond 10% of the part tolerance.
