GF Gage R0350606GNK M3.5x0.6 6G No-Go Thread Ring Gage

This is a new GF Gage (GFII series) No-Go thread ring gage, part number R0350606GNK, designed to inspect M3.5 x 0.6 metric external threads to ISO 6G tolerance class. The gage body is hardened and ground tool steel with a knurled OD for secure handling; three relief holes on the face confirm the standard adjustable ring gage construction, and a radial split with locking screw allows field setting to a master setting plug. The No-Go member verifies that the minimum material condition (maximum pitch diameter) of a 6G externally threaded fastener or part is not exceeded — a part that does NOT pass through this gage is conforming, per ASME B1.16M/ISO 1502 go/no-go gaging practice. Stamped markings on the face read "M3.5 x 0.6 / 6G" and "GR GAGE," and the packaging label confirms part number R0350606GNK and "GFII METRIC RING 6G NO GO," making identification unambiguous.
