Measuring attachment — BSW 55° thread measurement accessory by Microtech Metrology

Measuring attachment for rapid, repeatable inspection of BSW threads using a 55° flank angle; intended as an accessory for metrology instruments and gauges.

• Precision 55° flank geometry for BSW threads
• Compatible with 4.5 mm thread pitch
• Accessory for metrology instruments

Reliable geometry for reproducible thread checks

The accessory is engineered around the 55° flank angle required for BSW (British Standard Whitworth) threads, ensuring that contact occurs at the correct flank geometry and that measurement results are consistent across repeated checks. With a defined thread pitch 4.5 mm, the attachment aligns interrogation points so that a measurement system records the effective profile rather than artefacts from misaligned contact. This technical design reduces setup iterations and contributes to faster cycle times in incoming inspection and quality checks. The result is a measurable increase in repeatability and a lower likelihood of false rejects during batch verification.

Seamless integration with metrology equipment

Designed as an accessory for dial gauges, digital comparators or bench measuring fixtures, the attachment fits into existing inspection workflows without extensive modification. The compact interface and secure mounting promote stable contact during measurement sequences, which is particularly important when integrating with height gauges or bench comparators used in calibration labs and production testing. By providing a dedicated contact geometry for BSW threads, the component removes the need for improvised adapters and helps to standardise procedures for thread verification in the workshop and laboratory environment. This integration capability supports efficient quality assurance and shortens setup times for repeat inspections.

Practical advantages for workshop and laboratory use

As a specialised metrology accessory, the unit brings clear practical benefits: consistent contact geometry lowers operator influence, a repeatable pitch reference simplifies pass/fail decisions, and the accessory’s form factor keeps handling straightforward during routine checks. The part is best applied where BSW thread forms are present on components that require fast verification during assembly or final inspection. The compromise between focused functionality and simple handling is aimed at service departments, toolrooms and inspection benches that demand dependable results with minimal overhead. Built as a precision accessory by Microtech Metrology, the attachment supports structured inspection routines and contributes to a traceable quality record when used as part of an established measurement process.
