Thread Plug Gauge UNEF 15/16 x 20 — 2B, hardened gauge steel (Metav IndustryLine)

A Thread Plug Gauge UNEF 15/16 x 20 (2B) designed for quick verification of internal thread form and tolerance in workshop and quality‑control environments.

• Right-hand UNEF 15/16 x 20 thread form
• Tolerance class 2B to ANSI/ASME B1.1
• Hardened gauge steel construction
• Inspection grade for workshop use

Fast, unambiguous pass/fail control for UNEF threads

A hardened gauge steel plug provides a tactile, immediate check of internal threads. The 15/16 x 20 designation identifies the nominal diameter and thread density (20 threads per inch), while the 2B tolerance class denotes the standard internal thread fit defined by ANSI/ASME B1.1. Using this plug gauge streamlines inspection routines: if the gauge engages smoothly to the limit shoulder the thread is within tolerance, otherwise the feature is flagged for correction. This simple method reduces measurement time and prevents prolonged setup checks on the production line.

Consistent measurement behaviour that reduces rework

The right‑hand UNEF geometry and hardened material mean the gauge resists wear and maintains form under repeated use; this promotes reproducible checks over many cycles. For shops and inspection benches, reproducibility translates directly into lower scrap rates and fewer customer complaints because the inspection tool enforces the same acceptance criterion every time. The physical gauge removes ambiguity that can occur with subjective visual checks or improvised gauges, offering a robust means to protect assembly fit and functional reliability.

Standards compliance that supports quality systems

Conformity to ANSI/ASME B1.1/B1.2 and the explicit 2B tolerance class ensures compatibility with common engineering drawings and inspection plans. For procurement and quality teams, this means the gauge can be referenced directly in control plans, certificates and inspection records. The compact, single‑piece design suits routine checks in machine shops, toolrooms and incoming inspection, where traceable, standardised methods are required for auditability and supplier acceptance.

FAQ

What size and thread form does this gauge check?
The Thread Plug Gauge UNEF 15/16 x 20 (2B) checks internal UNEF threads with a nominal size of 15/16" and 20 threads per inch.

Is the gauge suitable for use in a workshop inspection routine?
Yes. The Metav IndustryLine plug gauge is manufactured as an inspection grade tool intended for workshop and quality‑control benches and is robust enough for frequent use.

What standard and tolerance does the gauge conform to?
This gauge conforms to ANSI/ASME B1.1/B1.2 and verifies the 2B tolerance class for internal threads.

What material is the gauge made from and why does that matter?
The gauge is made from hardened gauge steel, which preserves thread form under repeated engagement and ensures consistent inspection results.

Can this gauge be referenced in quality documentation?
Yes. The Metav IndustryLine plug gauge (SKU M315.929.EF) can be recorded in control plans and inspection records as the acceptance tool for the specified UNEF thread.
