Thread plug gauge G 1/2 Whitworth, right‑hand — Metav IndustryLine, hardened gauge steel, DIN ISO 228

Thread plug gauge G 1/2 Whitworth, right‑hand for rapid verification of internal pipe threads in production and inspection environments

• Hardened gauge steel construction
• Conforms to DIN ISO 228 standard
• G 1/2 Whitworth right‑hand thread
• Medium tolerance for general inspection

Assured conformity for pipe thread inspection

A robust thread plug gauge delivers a straightforward go/no‑go assessment of internal pipe threads; the M315.304 model is manufactured to meet DIN ISO 228, ensuring compatibility with industry‑standard Whitworth pipe fittings. The specified 14 tpi pitch and right‑hand form make this gauge suitable for routine acceptance testing and spot checks in plumbing, hydraulic and plant‑engineering applications. By checking thread form and basic dimensions against a recognised norm, the gauge reduces the risk of assembly faults and rework, supporting a stable production flow.

Durable materials that cut maintenance intervals

Built from hardened gauge steel, the plug gauge resists wear from repeated trial fittings and retains dimensional stability during normal workshop use. The medium tolerance classification provides a balance between interchangeability and manufacturing cost, making the tool well suited to repetitive inspection tasks. The compact mass (approx. 0.22 kg) and simple geometry allow handheld use without rapid operator fatigue, while the hardened finish lowers the frequency of replacements—an economic benefit for busy inspection benches.

Designed for practical workshop use and traceability

The right‑hand G 1/2 Whitworth form is explicitly identified to prevent mismatches with left‑hand or metric fittings; clear identification reduces process errors on the shop floor. The simple, recognisable geometry of the plug gauge expedites operator training and routine checks. For inventory and procurement, the item is stocked under SKU M315.304 and carries a GTIN for traceability, making integration into quality‑management systems and procurement workflows straightforward. The gauge is recommended for use where fast, reliable pass/fail decisions are required.

Where this gauge performs best

This plug gauge is intended for general inspection and assembly control of internal Whitworth pipe threads, especially in mechanical engineering, maintenance shops and installation work where standardised pipe connections are common. The medium tolerance class supports a pragmatic approach to inspection frequency and sampling plans without demanding high‑end metrology resources. For specialised laboratories requiring micro‑precision beyond standard norms, alternative high‑precision instruments should be considered.

FAQ

What is the plug gauge used to check?
The plug gauge M315.304 checks internal Whitworth pipe threads of size G 1/2 Whitworth (right‑hand) for basic conformity with DIN ISO 228.

Which material is the gauge made from?
The gauge is made from hardened gauge steel, selected for wear resistance and dimensional stability.

What does the Medium tolerance class mean for inspection?
Medium tolerance indicates suitability for routine workshop inspection where repeatable, norm‑based go/no‑go checks are required without laboratory‑grade precision.

Can this gauge be used on left‑hand threads or metric fittings?
No—the tool is manufactured as a right‑hand Whitworth plug gauge and is not suitable for left‑hand or metric thread forms.

How is the thread specified on the gauge?
The thread is specified as G 1/2 Whitworth with a 14 tpi pitch and right‑hand orientation.
