Industrial ITG.5625-12 UNC-2B GO PD.5084 NOT GO PD.5152 Thread Plug Gage

Industrial ITG's thread plug gauge is a precision tool for checking internal UNC threads sized 0.5625-12 with a 2B tolerance, suitable for production, repair, and inspection tasks where thread quality matters. The Go plug has a pitch-diameter (PD) of 0.5084 in and the Not-Go plug is 0.5152 in, enabling quick go/no-go verification of thread engagement and form against the nominal 0.5625-12 UNC specification and ensuring the part will accept mating fasteners consistently. Used in quality control within manufacturing, it helps verify that components will properly mate with fasteners and assemblies requiring accurate internal threading, reducing the risk of cross-threading and improper thread engagement. Measurements are provided in inches to align with common shop tooling and standard practice for gauging internal threads of this size and pitch, making it a straightforward addition to dimensional inspection regimes.
