Thread Ring Gauge UNEF GO 1 5/16" x 18, Tolerance 2A — Metav IndustryLine

A Thread Ring Gauge UNEF GO 1 5/16" x 18 2A for fast, repeatable inspection of external UNEF threads in production and quality control

• UNEF thread 1 5/16" x 18 specification
• Tolerance class 2A for go gauging
• Hardened gauge-steel construction
• Conforms to ANSI/ASME B1.1/B1.2 standards

Consistent go/no‑go control for external UNEF threads

A GO ring gauge of this size offers an efficient, objective way to check external UNEF threads during machining and assembly. Designed to the ANSI/ASME B1.1/B1.2 profile and built to tolerance class 2A, the gauge verifies that an external thread falls within acceptable dimensional limits. By reducing subjective judgement in inspection, the tool improves process reliability and helps maintain interchangeability across batches and suppliers.

Durable construction for repetitive production use

Manufactured from hardened gauge steel, the ring gauge resists wear and maintains measurement integrity over repeated cycles. The right-hand thread form and robust material selection mean fewer replacements and steady inspection results, which lowers downtime and long‑term costs. For shop-floor applications where rapid pass/fail decisions are routine, the long service life of this gauge supports predictable maintenance planning and traceable quality checks.

Clear inspection workflow reduces rejects and rework

Using a dedicated GO gauge streamlines the inspection step: a simple assembly check rapidly confirms conformity, enabling immediate sorting or release. The specification 1 5/16" x 18 and 18 tpi pitch match common UNEF requirements, so the gauge integrates seamlessly into existing QC steps. This tangible speed and clarity in inspection contributes to reduced scrap rates, improved throughput and faster decision-making in production environments.

FAQ

What is this gauge used for?
This ring is a GO gauge for quick pass/fail inspection of external UNEF threads; the Thread Ring Gauge UNEF GO 1 5/16" x 18 confirms that machined threads meet the 2A tolerance.

Does the gauge comply with international standards?
Yes, the tool is manufactured to the ANSI/ASME B1.1/B1.2 thread form and intended for use where that standard applies.

Which materials is the gauge suitable for inspecting?
The gauge inspects external threads regardless of workpiece material; the hardened gauge-steel construction ensures durability during repeated checks on common production materials.

How does tolerance class 2A affect acceptance criteria?
Tolerance class 2A specifies the permissible dimensional limits for the external thread; the GO gauge confirms whether a workpiece thread falls within those limits for acceptance.

Can this gauge be used on left-hand threads?
No, this model has a right-hand thread form and is intended for right-hand UNEF thread inspection only.
