Thread Gauge Ring G 1/8 (GO) — Whitworth, Right‑hand, Hardened Gauge Steel by Metav IndustryLine

A Thread Gauge Ring G 1/8 (GO) Whitworth for right‑hand pipe‑thread inspection, built for repeatable pass/fail checks in workshop quality control and production inspection

• Whitworth GO gauge for G 1/8 threads
• Hardened gauge steel for long service life
• Conforms to DIN ISO 228 inspection standard
• Tolerance class A for tight acceptance limits

Reliable GO inspection tailored to Whitworth pipe threads

The GO ring provides a quick, objective check of external pipe threads, ensuring that mating parts will assemble without interference. Engineered as a GO gauge for G 1/8 Whitworth form, the ring verifies the upper acceptance limit and thereby prevents rework or assembly failures. Conformity to DIN ISO 228 and tolerance class A gives measurable assurance within production control systems, reducing scrap and accelerating quality decisions during batch inspection. The compact form factor supports efficient inline checks and minimises handling time.

Durable construction for frequent shop use

Manufactured from hardened gauge steel, the inspection ring resists wear from repeated engagement and keeps dimensional stability across many cycles. The compact mass and robust material mean the gauge preserves the specified limits under normal shop conditions, which supports consistent pass/fail results over time. Reduced maintenance and predictable longevity translate into lower lifecycle costs and less downtime for calibration or replacement, making this ring a practical instrument for continuous inspection workflows.

Traceable compliance for documented quality assurance

Marked with the SKU M315.321, the gauge supports traceability in documentation and process control. The Whitworth thread form and the listed thread pitch 28 are suited to standard pipe-thread verifications where interchangeability is required. Use of this ring in inspection routines aligns with documented procedures and audits, helping to demonstrate adherence to recognised standards. Clear identification and consistent acceptance criteria simplify communication between production, inspection and purchasing functions.
