Precision GO Thread Plug Gauge (Tol. 6H) - M 44 x 1.5

• Check threads with a functional limit gauging method for routine inspection decisions.
• Use in production control, incoming inspection, and maintenance workflows where a fast pass or fail result is required.
• Select by thread designation as stated in the product name: M 44 x 1.5.
• Select by tolerance class as stated in the product name: 6H.
• Apply manual engagement only and stop when resistance becomes significant, without forcing the gauge.
• Keep threads and gauge surfaces clean to reduce measurement risk and wear.

Note Maintain cleanliness and avoid impact loads. Store the product protected and dry.

• Fast pass or fail thread verification without measurement setup
• Supports consistent inspection decisions in production control
• Helps detect out of tolerance threads before assembly
• Suitable for routine checks in workshop and quality environments

• Limit gauge only, it does not provide the numeric deviation from nominal
• Not intended for automated gauging without a dedicated fixture

1. Clean the thread and remove debris, chips, and residual lubricant.
2. Wipe the gauge measuring surfaces and visually check for contamination.
3. Align the gauge straight to the thread axis and start engagement by hand.
4. Turn the gauge with steady manual torque and stop when resistance becomes significant.
5. Interpret the result according to the GO or NO GO function stated for the gauge type.
6. Document the inspection outcome and segregate nonconforming parts.
7. Clean the gauge after use and store it protected from impact and corrosion.

How do you select the correct gauge?
Match the thread designation and tolerance class in the product name to the drawing requirement. Confirm the thread system if it is stated in the product name.

How do you avoid false inspection results?
Clean thread and gauge surfaces, align the gauge to the axis, and apply controlled manual torque only. Avoid forcing the gauge through resistance.

What does GO and NO GO mean for thread gauging?
GO verifies the functional fit condition within limits. NO GO verifies the reject limit and must not engage beyond the allowance defined by your inspection practice.

Do you need calibration documentation for traceability?
Depending on your quality system, you can use calibrated gauges and documented inspection intervals. Define intervals based on usage and risk.

How do you maintain the gauge in service?
Clean after use, protect from impact, and store dry with light corrosion protection. Replace the gauge if damage or wear is suspected.
