Osg 1500201900 Plug Thread Gage M16x2.0 6H Double End

Product Description

The OSG 1500201900 is a double-end plug thread gage designed to verify M16x2.0 internal threads to the 6H tolerance class. One end carries the Go member and the opposite end carries the No Go member, allowing a technician to confirm both the minimum and maximum thread tolerance in a single tool. The gage body is machined from high speed steel for dimensional stability and wear resistance. A handle is included. This tool is used in production, inspection, and maintenance environments wherever M16x2.0 threaded bores must be verified before assembly.

This plug thread gage suits any application requiring inspection of M16x2.0 6H class internal threads. Typical use cases include manufacturing quality control, MRO inspection, and field verification of threaded holes in mechanical assemblies. Machinists, quality technicians, and maintenance professionals use this gage to confirm that tapped holes will accept a mating fastener within specification. The double-end design eliminates the need to handle a separate Go and No Go gage, reducing inspection time and the chance of mixing tools.

Key Features

• Go and No Go members on a single double-end gage for complete 6H tolerance verification
• M16x2.0 thread form for metric fastener inspection
• High speed steel construction for wear resistance and dimensional stability
• Handle included — no separate handle purchase required
• 6H classification suits standard commercial and industrial metric thread fits

Compatibility

Designed for inspection of M16x2.0 internal threads manufactured to the 6H tolerance class per standard metric thread specifications.

Installation Notes

Thread gages are inspection tools and do not require installation. Before use, clean the threaded bore and gage members of chips, oil, and debris to ensure accurate readings. The Go end should pass through the full thread length under hand pressure only — never force it. The No Go end should not enter the thread; if it does, the bore is out of tolerance and must be evaluated before assembly.
