VERMONT GAGE 911319050 Class ZZ Pin Gage, Black Guard, Plus, 0.1905 Inch Size

Vermont 911319050 Class ZZ 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 911319050 Class ZZ pin gauge 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 a 10 microinch finish or better with heat-treated hardness.
• It is designed for quick and accurate measurements, checking locations and calculating the distances between holes & gauge slot widths.

Standards and Approvals:

• ISO 17025
• NIST

Frequently Asked Questions:

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. 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. 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 ZZ tolerance mean?

A. These gauges have an inch tolerance of 0.0002 inches and a Metric tolerance of 0.005 mm.
