• Covers 7–4.5 TPI thread range
• Compact inspection insert, 0.1 kg
• Compatible with measuring equipment

Reliable verification for Whitworth‑form threads

The insert is engineered to match the Whitworth 55° thread form, which means the flank geometry is correct for a precise fit during tactile checking and comparative inspection. By providing a fixed reference geometry for the thread form, the component reduces interpretative error during routine checks and supports repeatable results. The defined 7–4.5 TPI range ensures applicability to common coarse Whitworth threads, enabling straightforward use in workshops and metrology labs that work to imperial thread specifications. This targeted compatibility streamlines inspection stages and shortens set‑up times on measuring fixtures.

Practical benefits for inspection workflows

As a small, purpose‑built accessory, the insert offers tangible efficiency gains: reduced adjustment cycles on thread gauges and a lower risk of misreading due to incorrect profile matching. Its light weight (approx. 0.1 kg) and compact form make it easy to house within a gauge set or to fit into modular measuring fixtures without requiring extensive modification. Designed for production and inspection environments, the insert supports faster decision cycles in quality control and contributes to higher throughput when batch checking threaded parts, while maintaining the precision expected in standards‑driven workflows.

Traceability and integration into measuring systems

Each item is identifiable by its SKU M309.098.8 and GTIN 4054469118390, which facilitates inventory management and traceability across quality documentation. The accessory integrates with existing measuring equipment intended for thread inspection and complements a structured inspection routine by providing a stable reference for comparative measurements. Where traceability and documentation matter, the clear identification supports quality records and audit trails, reinforcing reproducibility in serial testing and acceptance procedures.
