55° Thread Measurement Attachment For 55° Thread Angle - Microtech Metrology

The combination of a true 55° profile and suitability for BSF/Whitworth threads ensures reliable verification of classic thread forms while reducing rework and inspection time; the attachment is matched to a 4.5 mm pitch for targeted measurements. Order the measuring attachment directly via Metav Werkzeuge or ask our consultants if needed.

Measuring Attachment BSF 55° – Thread measuring attachment, 55° profile (Microtech Metrology)

The Measuring Attachment BSF 55° is a precision accessory for comparative and profile-based thread inspection, designed to verify 55° BSF/Whitworth thread forms and intended for use with precision comparators and gauges

• 55° profile for BSF/Whitworth thread measurement
• Designed for 4.5 mm thread pitch verification
• Compatible with Microtech Metrology gauges

Reliable profile control for classical thread standards

The attachment provides a 55° flank geometry that matches the traditional BSF/Whitworth thread form, allowing straightforward verification of profile conformity. By offering a defined contact geometry for the flank faces, the device reduces interpretative errors during visual or comparator-assisted inspection. The controlled contact and dedicated geometry convert profile assessment into a repeatable, comparable measurement, which supports faster decisions in incoming inspection and in-process checks while maintaining documented traceability.

Smooth integration with precision comparators and gauges

Manufactured to interface with standard comparator fixtures, the accessory ensures simple mechanical compatibility with established measurement rigs from Microtech Metrology and similar systems. The matching to a 4.5 mm pitch makes it suitable for the specific BSF sizes where that pitch applies, avoiding over-generalisation and ensuring that the tool is used where it delivers best accuracy. The design prioritises robust seating and repeatable orientation so that each measurement cycle begins from the same reference, enabling consistent results across shifts and operators.

Practical advantages for workshop and quality control applications

With a focus on measurement efficiency and trustworthy verification, this thread measuring solution helps to reduce non‑conforming parts progressing through production. The defined profile contact simplifies operator training and shortens inspection times, which benefits both small toolrooms and larger quality departments. Where documentation is required, the attachment supports clear pass/fail decisions and can be combined with comparator readings for recorded evidence. The result is improved process stability and fewer returns or reworks due to thread-profile deviations.
