Vermont Gage 361136550 Ring Gage

The Vermont Gage 361136550 is a threaded ring gauge designed for verifying UNC thread dimensions. It serves machinists and quality technicians who need to confirm external thread compliance on 7/16"-14 fasteners.

Questions about this item

How do I install the Vermont Gage 361136550 ring gage into a holder and which step is often missed?

Mount the gage into a compatible 3T holder, then lock the adjustable mechanism so the Go and No-Go members stay fixed during use.

What maintenance will the tool-steel gage need over time?

Keep the uncoated surfaces lightly oiled to prevent rust, and periodically verify the Go pitch diameter of .3897 in and No-Go pitch diameter of .385 in against a calibrated master.

Which limit appears first when the gage is used continuously on 7/16"-14 UNC threads?

The adjustable locking mechanism can loosen under repeated threading cycles, allowing the Go/No-Go setting to shift before the RC 60-62 tool steel shows measurable wear.
