1/4" 32 TPI UNEF Thread Ring Gauge GO Right-Hand Hardened Gauge Steel ANSI/ASME B1.1/B1.2 - Metav IndustryLine

Take the assurance of a purpose-made GO ring gauge constructed from hardened gauge steel, combined with ANSI conformity and a compact 1/4‑32 UNEF form, to streamline thread acceptance checks in production. Order the gauge directly via Metav Werkzeuge or consult our specialists for integration into existing inspection routines.

Thread ring gauge UNEF GO, 1/4‑32 ANSI B1.1 / 2A — Metav IndustryLine; hardened gauge steel, tolerance class 2A

A Thread ring gauge UNEF GO, 1/4‑32 ANSI B1.1 / 2A designed for rapid verification of external thread form and dimensional acceptance in manufacturing and inspection environments

• Hardened gauge steel construction
• ANSI B1.1 compliant thread form
• Tolerance class 2A GO gauge
• Compact 1/4‑32 UNEF size

Consistent pass/fail verification for production control

A GO ring gauge provides an immediate, objective check for external threads: the part either enters the gauge (pass) or it does not (fail). Built to the ANSI B1.1 profile and finished to tolerance class 2A, this gauge reduces interpretation variance and speeds up quality decisions on the shop floor. The simple physical check complements dimensional measuring equipment by offering a fast, reproducible acceptance criterion that fits inline inspection points or final checks before assembly.

Durable construction for long service life and repeatability

Manufactured from hardened gauge steel, the ring resists wear and maintains profile integrity over extended use, preserving high repeatability of go/no‑go results. Heat treatment and finishing reduce the risk of profile distortion, so calibration intervals can be extended compared with untreated tools. Where traceability is required, periodic verification with a competent calibration service ensures continued conformity to the specified tolerance class and maintains process confidence.

Practical integration into inspection workflows

Sized for common fine threads, the 1/4‑32 UNEF ring is compact and straightforward to handle for production inspectors and incoming goods teams. The right‑hand thread form suits standard fasteners and turned components; the gauge is primarily for external thread checks and complements full metrological inspection when a dimensional record is required. Use the ring for rapid sorting of batches, first‑off checks or final acceptance steps to reduce rework and keep assembly lines moving.

FAQ

What is the purpose of this GO ring gauge?
The ring gauge is used to perform quick pass/fail verification of external threads against the 1/4‑32 UNEF profile and tolerance class 2A, ensuring components meet the ANSI thread form before assembly or dispatch.

Is the gauge compliant with recognised standards?
Yes, the product conforms to ANSI/ASME B1.1/B1.2 and is supplied as a GO ring gauge for the 1/4‑32 UNEF thread form (SKU M315.950.EF, Metav IndustryLine).

Which components can be inspected with this gauge?
External threaded components such as turned parts, fasteners and machined studs that use the 1/4‑32 UNEF thread form can be checked for acceptance with this GO ring gauge.

How should the gauge be maintained to preserve accuracy?
Clean after use, protect from impact, and store in a dry environment; schedule periodic verification by a calibration provider to confirm continued conformity to tolerance class 2A.

What is included with delivery?
Delivery comprises the GO ring gauge as specified (1/4‑32 UNEF, tolerance class 2A); for calibration certificates or additional documentation, please consult Metav Werkzeuge.
