Dưỡng kiểm ren ngoài GO chính xác (Tol. 2A) - UNF số 12 x 28

• 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: UNF số 12 x 28.
• Select by tolerance class as stated in the product name: 2A.
• Thread system reference: UNF.
• 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.

Lưu ý Clean the functional surfaces after use and store the product protected from contamination.

• 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 Chất bôi trơn cắt gọt ren.
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.
