BSW 55° measuring attachment — thread measuring attachment set for 4–9 TPI by Microtech Metrology

The BSW 55° measuring attachment is an accessory designed for reliable inspection of British Standard Whitworth thread profiles, ideal for workshop and inspection‑room use.

• BSW 55° profile for Whitworth threads
• Covers 4–9 TPI pitch range
• Set of 7 interchangeable gauges

Precision where Whitworth threads matter

The attachment delivers a clear, reproducible reference for the 55° Whitworth profile, reducing ambiguity in visual and tactile checks. Supplied as a compact 7‑piece set, the kit spans the common coarse pitches between 4–9 TPI, enabling fast verification across a typical range of Whitworth fasteners. The modular design of the interchangeable heads simplifies selection of the correct pitch and keeps changeover time to a minimum, which supports efficient inspection cycles and lowers the risk of incorrect assessments.

Practical benefits that speed inspection workflows

Engineered as an accessory for measuring instruments and comparators, this set is intended to streamline routine checks and troubleshooting. Using a dedicated profile head for each pitch reduces adjustment errors compared with single‑tool approximations, producing consistent pass/fail decisions and fewer reworks. The compact format keeps the tools accessible at the bench and the clear pitch labelling helps avoid mix‑ups during repetitive tasks, improving throughput without sacrificing accuracy.

Compatibility and application scenarios

This thread measuring attachment is suitable for use wherever BSW threads must be inspected, from maintenance shops to production quality stations. The 4–9 TPI coverage addresses common sizes encountered in British‑standard assemblies, while the set format supports multipoint checks across small batches or prototypes. The simplicity of the heads permits rapid exchange and inspection sequences, which is particularly useful when multiple thread sizes appear on the same assembly or during incoming goods inspections.

Quality assurance and workshop integration

Manufactured by Microtech Metrology, the kit is a purpose‑built accessory for thread profile verification rather than a measuring instrument in its own right. Its role is to provide a dependable reference geometry for inspection workflows, helping to establish clear criteria during audits and reducing subjective interpretation. When combined with a suitable comparator or fixture, the attachments aid repeatable decision making and support traceable quality routines.
