Description
SHS Thread Plug Gauge UNF 1/4–5/8
A thread plug gauge checks an internal thread with two ends: the GO end must screw in the full depth, the NO-GO end must not start. That pass/fail answer is the whole point — it does not measure, it decides.
Available Sizes
- UNF 1/4-28
- UNF 5/16-24
- UNF 3/8-24
- UNF 7/16-20

Key Features
- GO end enters the full thread depth; NO-GO must not engage more than a turn or two
- Supplied as a matched GO/NO-GO pair on one handle
- Never force a NO-GO end — that is how a reference gauge is destroyed
