55° Thread Measurement Attachment BSW For Precision Calipers - Microtech Metrology

Take advantage of a compact solution that targets Whitworth threads precisely: the combination of BSW 55° profile geometry and a defined 4 mm pitch reduces inspection uncertainty and accelerates pass/fail decisions on the shop floor. Order the attachment directly via Metav Werkzeuge or consult our specialists for confirmation of compatibility.

Measuring attachment — BSW 55° thread measuring attachment, 4 mm pitch (Microtech Metrology)

A precision measuring attachment for inspecting BSW 55° (Whitworth) thread forms in metrology and workshop quality checks

• BSW 55° profile for Whitworth threads
• Designed for 4 mm thread pitch
• Accessory for precision thread inspection
• Suitable for metrology accessories range

Faster, more reliable Whitworth thread inspection

The BSW 55° profile is the established geometry for Whitworth threads; using an attachment matched to that angle removes guesswork during checks. By fitting a dedicated profile the measurement process becomes more direct, improving repeatability and reducing rework. This accessory converts visual or tactile checks into a defined inspection step, so decisions on conformity are documented and reproducible. The clear mechanical definition of the profile helps standardise inspection routines across production shifts and incoming inspection.

Angle and pitch explained for practical use

A 55° flank angle defines the Whitworth form and the specified 4 mm pitch identifies the axial spacing of the thread. In practice, these two parameters determine whether a thread engagement will perform as intended: the angle controls load distribution along the flanks, while the pitch governs axial alignment. The attachment is shaped to match that geometry, so measurements reflect the intended design rather than an approximated fit. For teams less familiar with thread theory, matching the inspection profile to the design profile offers an immediate assurance of geometric conformity.

Integrating the accessory into quality workflows

As an inspection accessory from Microtech Metrology, this component is intended to be used where documented thread verification is required. Its compact form supports quick exchange into existing measurement setups and helps maintain a smooth throughput in recurring quality checks. The result is a tangible reduction in inspection ambiguity and an improved audit trail for traceability. For suppliers and small workshops alike, a purpose-made inspection profile delivers measurable efficiency gains when incorporated into regular quality-control cycles.
