Gewinde‑Lehrdorn UNEF, 1.1/4 x 18 ANSI B1.1 / 2B — Metav IndustryLine plug gauge, right‑hand thread

Gewinde‑Lehrdorn UNEF, 1.1/4 x 18 ANSI B1.1 / 2B is a right‑hand thread plug gauge designed to verify internal UNEF threads to industry standards in production and inspection environments

• Hardened gauge steel construction
• Conforms to ANSI/ASME B1.1/B1.2 standards
• UNEF 1¼″ × 18 TPI, tolerance class 2B
• Right‑hand thread for internal inspection

Standards‑based inspection for consistent acceptance decisions

The plug gauge verifies internal UNEF threads to the ANSI/ASME B1.1/B1.2 standard, offering a clear go/no‑go criterion for tolerance class 2B checks. Built from hardened gauge steel, the tool resists wear during repeated use, which preserves dimensional integrity and reduces measurement drift in series production. Using a dedicated plug gauge simplifies conformity checks compared with comparative or subjective methods, providing a quantifiable basis for acceptance that supports quality control procedures and audit trails.

Robust design for repetitive workshop use

Designed as a compact and durable inspection tool, the gauge combines a precise thread form with a wear‑resistant material to maintain repeatability in daily use. The UNEF 1 1/4" × 18 TPI geometry suits fine‑pitch applications where thread fit and engagement are critical; tolerance class 2B is the standard internal fit for many engineering assemblies. The right‑hand configuration matches conventional threaded parts, while the hardened construction reduces risk of nicks and deformation, helping to ensure that routine inspections remain reliable over long production runs.

Clear provenance and procurement advantages

Each item is supplied with traceable identification suitable for controlled procurement: a manufacturer SKU and GTIN are provided so the gauge can be logged into stores and calibration systems. Sourcing through Metav IndustryLine delivers the advantage of a European distribution and stock hub in Emmerich, combining broad product range with industrial quality assurance. For workshop managers, the combination of standard conformity, durable construction and clear labelling simplifies logistics and helps integrate the gauge into incoming inspection or final acceptance processes.
