Measuring attachment BSF 55° – Thread measuring accessory (Microtech Metrology)

A measuring attachment BSF 55° for precise inspection of British Standard Fine threads and routine thread-control tasks on comparators and gauge fixtures

BSF 55° thread profile compatibility
Suitable for 11 TPI thread pitches
Precision metrology accessory for comparators

Faster, more reliable thread inspection in production

This accessory speeds up inspection routines by providing a dedicated contact geometry for BSF profiles. Fitting a dedicated profile head reduces setup time and eliminates repeated manual alignment, which increases throughput in quality control. The unit’s geometry is designed to reproduce the 55° flank angle consistently, helping to keep measurement scatter low and make pass/fail decisions quicker. Its focus on repeatable contact conditions supports efficient sampling for batch inspection and reduces rework rates in production.

Designed specifically for BSF 55° profiles and 11 TPI pitches

Engineered to match the British Standard Fine profile, the attachment is tailored for threads with 11 TPI, ensuring the correct flank angle and pitch engagement during measurement. This reduces the risk of misinterpretation that can occur when generic probes are used. The technical adaptation for the 55° form means the accessory can be used as a reliable reference when checking thread form and lead, giving a precise mechanical interface between the workpiece and the measuring instrument. For workshops that inspect British-standard components, this translates into clear, comparable results across multiple parts and operators.

Built for integration, traceability and workshop use

The accessory is suitable for mounting on common comparator and gauge setups, offering straightforward mechanical integration so inspection lines remain productive. Its robust design supports repeated use in workshop environments while maintaining measurement integrity. Where traceability is required, the accessory can be recorded as part of an inspection setup, aiding process documentation and quality systems. Combining precision geometry with easy fitting improves operator confidence in routine checks and contributes to a steady workflow in both small repair shops and larger inspection departments.
