Thread plug gauge UNC, 1/2 x 13 ANSI B1.1 / 2B — plug gauge for internal UNC threads, hardened gauge steel, ANSI/ASME compliant (Metav IndustryLine)

A Thread plug gauge UNC, 1/2 x 13 ANSI B1.1 / 2B for rapid verification of internal thread form and fit according to ANSI/ASME standards in production and inspection environments

• ANSI/ASME B1.1/B1.2 compliance
• Hardened gauge steel construction
• Tolerance class 2B for internal threads
• For UNC 1/2‑13 thread inspection

Consistent conformity for production and quality control

The thread plug gauge provides a fast, objective check of internal threads, giving operators and inspectors a reliable go/no‑go verdict at the point of production. Built to ANSI/ASME B1.1/B1.2, the gauge ensures conformity with widely recognised thread geometry standards, helping to reduce rework and scrap by catching deviations early. The hardened construction maintains form stability under repeated use, supporting consistent pass/fail decisions that speed up inspection cycles and support lean manufacturing routines.

Robust construction that keeps measurements repeatable

Manufactured from hardened gauge steel, this plug gauge resists wear and preserves the critical thread profile over long service life, which translates into lower total cost of ownership and fewer calibration cycles. The tolerance class 2B indicates the internal thread quality it verifies, making the gauge suitable for typical machine‑shop and assembly applications where reproducible internal thread fit is required. The compact, tool‑grade design supports quick handling and secure seating in threaded bores, contributing to reproducible tactile feedback during inspection.

Practical integration into workshop and inspection workflows

The gauge’s 1/2‑13 UNC specification and clear pass/fail function simplify its use across production lines, assembly benches and quality control stations. Its straightforward operation reduces training time for operators while its standards conformity facilitates communication with suppliers and customers about thread acceptance criteria. In combination with documented inspection procedures, the gauge supports traceable quality records and helps maintain assembly reliability where threaded joints are critical.

FAQ

What is the intended use of this plug gauge?
The plug gauge is designed for go/no‑go verification of internal 1/2‑13 UNC threads and confirms compliance with the specified thread form and fit.

Which standards does the gauge comply with?
The gauge is manufactured to ANSI/ASME B1.1/B1.2 thread geometry requirements to ensure compatibility with common UNC thread specifications.

What material is the gauge made from and how does that help?
Made from hardened gauge steel, the gauge resists wear and preserves thread profile accuracy during repetitive inspections.

What does tolerance class 2B indicate for internal threads?
Tolerance class 2B denotes the standard internal thread tolerance band for general‑purpose UNC threads, applicable in typical machine‑shop and assembly contexts.

Is the gauge suitable for production use on an inspection bench?
Yes, the plug gauge is intended for routine production and quality‑control use, providing rapid and repeatable go/no‑go checks.
