M315.302 – Pipe Thread Gauge Plug G 1/4 Whitworth (right-hand), hardened gauge steel

The pipe thread gauge plug G 1/4 Whitworth (right-hand) is a dedicated go/no-go inspection tool for internal pipe threads in workshop and production environments.

• Hardened gauge steel construction
• Conforms to DIN ISO 228 standard
• Right-hand Whitworth G 1/4 size
• Tolerance class: Medium for routine checks

Consistent thread inspection through standard conformity

The M315.302 is designed for straightforward verification of internal pipe threads and is manufactured to conform with DIN ISO 228, which ensures compatibility with widely used industrial thread standards. The specification for G 1/4 provides a clear reference for thread form and function, while the documented tolerance class Medium makes the gauge suitable for routine production control rather than precision laboratory grading. By using a dedicated plug, the inspection process becomes a fast go/no-go decision that reduces cycle time at the inspection station and helps to prevent the release of incorrectly threaded components.

Robust materials and handling for repetitive use

Constructed from hardened gauge steel, this inspection plug delivers resistance to wear and retains its form under repeated engagement with internal threads. The compact mass of 0.05 kg makes handling and rapid exchange simple on the shop floor, while the right-hand Whitworth orientation matches the typical thread direction encountered in pipework and fittings. The hardened material and straightforward geometry give longevity and predictable performance, supporting stable measurement routines and minimising the need for frequent replacement.

Practical benefits for production and quality control

Integrating a purpose-made plug into a quality-control workflow streamlines inspection, reduces subjective judgement and supports faster throughput on assembly and maintenance lines. The plug’s clear definition and modest size make it suitable for bench inspection as well as in-line checks when space is at a premium. For manufacturers and maintenance teams seeking to reduce rework and ensure compatibility of threaded components, this type of gauge provides a practical balance of durability, standards conformity and ease of use that keeps operations moving.
