Thread gauge insert 48–40 TPI, 55° — Thread profile reference for Whitworth 55° inspection by Metav IndustryLine

The Thread gauge insert 48–40 TPI, 55° provides a compact reference profile for verifying Whitworth 55° screw threads in metrology and workshop quality control

• Compatible with Whitworth 55° profiles
• Nominal pitch 48–40 TPI
• Precision reference geometry
• Lightweight 0.1 kg

Accurate Whitworth reference for repeatable checks

The insert supplies a defined reference profile for Whitworth threads with a nominal pitch of 48–40 TPI and a flank angle of 55°, enabling quick functional checks of mating threads and gauges. As a verification aid, the piece helps to identify thread deformation and wear before parts reach final assembly. The clearly defined geometry reduces subjectivity in visual and tactile comparison, which supports faster go/no‑go decisions on the shop floor and in incoming inspection.

Quietly speeds up inspection workflows

Designed as a compact accessory for inspection benches and thread measuring setups, the insert is lightweight (approx. 0.1 kg) and easy to position. Integration into standard inspection routines avoids complex setups and shortens cycle times: the fixed profile is immediately usable with comparator gauges, profile projectors or camera inspection systems. The simple form factor lowers handling time and contributes to streamlined throughput without sacrificing control over thread conformity.

Stable reference for consistent quality control

Using a dedicated profile insert ensures consistent reference geometry across repeated measurements, supporting process stability and documented quality assurance. The item complements existing metrology equipment as an accessory and is suitable where consistent visual or instrumental comparison of Whitworth 55° threads is required. As part of a structured inspection regime, the insert helps to maintain traceable results and to reduce scrap through early detection of non‑conforming threads.
