Spi 37-193-0 Double End Plug Thread Gage M10x1.5 6H

Product Description

The SPI 37-193-0 is a double-end plug thread gage designed to inspect M10x1.5 internal threads to the 6H tolerance class. One end carries the Go member; the opposite end carries the No Go member. The Go end verifies that the thread will accept a mating fastener within specification. The No Go end confirms that the pitch diameter has not been cut oversize. Both ends share a single included handle, keeping the tool compact and ready for bench or floor use. Machinists, quality control inspectors, and precision manufacturing technicians use this gage as a fast, definitive pass-fail check during in-process and final inspection of tapped holes.

This gage is suited to shops producing or inspecting metric-threaded components where M10x1.5 is a common fastener size. Typical applications include automotive components, structural hardware, fluid fittings, and general industrial assemblies. The 6H tolerance class is the standard fit for most commercial and industrial M10 fastener applications, making this gage a high-frequency tool in any metric machining environment. The gage arrives with a traceability certification traceable to ANSI standards and calibrated to NIST, supporting quality management system documentation requirements.

Key Features

• Double-end design with Go and No Go members on a single handle — no tool swap required
• M10x1.5 thread size with 6H tolerance class for standard metric fit inspection
• Handle included — ready to use out of the box
• ANSI traceability certification and NIST-traceable calibration included for QMS compliance
• Compact profile: approximately 4.62 inches long and 0.58 inches in diameter
• Lightweight at 0.176 pounds — suitable for extended bench use

Compatibility

Designed for inspection of M10x1.5 internally threaded features conforming to the 6H tolerance class per standard metric thread specifications.

Installation Notes

Thread gages are inspection tools, not cutting tools — never force the Go or No Go member into a tapped hole. Clean chips and coolant from the threaded feature before gaging to avoid false readings or gage wear. Store the gage in its case when not in use to protect the thread form from damage. Periodic recalibration against a NIST-traceable master is recommended to maintain inspection integrity over time.
