55° Thread Measurement Adapter Set 4–11 TPI, Three-Point Contact - Microtech Metrology

Take advantage of the combination of a 55° thread profile, a practical 4–11 TPI range and a precision 9‑piece set to ensure repeatable, workshop-grade thread inspection. Order the measuring attachment directly via Metav Werkzeuge or ask our consultants if needed.

Measuring Attachment BSF 55° for Thread Measurement — 55° profile, 4–11 TPI (Microtech Metrology)

Measuring Attachment BSF 55° for thread measurement provides a compact solution for reproducible inspection of BSF threads in metrology and workshop quality control.

• 55° BSF thread profile compatibility
• Range 4–11 TPI for coarse threads
• Delivered as a precision 9-piece set

Consistent 55° profile checks for reliable thread conformity

The design focuses on a 55° profile that matches the BSF thread geometry used in classic coarse-thread applications. By matching the profile angle precisely, the attachment reduces interpretation variability during visual or comparative checks and supports repeatable assessment across batches. Built for metrology attachments, the insert helps establish a clear go/no‑go criterion and speeds up inspection cycles while maintaining documented traceability.

Broad coarse-thread coverage with straightforward compatibility

Covering the 4–11 TPI range, the set addresses the most common coarse BSF pitches encountered in restoration, heavy engineering and heritage component inspection. The measured pitch span allows one device to replace multiple single-purpose gauges, improving workflow efficiency. Where digital or analogue comparators are used for final verification, the attachment integrates with standard thread inspection stands and fixtures, enabling faster verification without compromising documented accuracy.

Practical set layout to streamline workshop metrology

Supplied as a 9‑piece set, the components are organised to simplify selection and reduce changeover time on the shop floor. The compact format supports bench-top use and is suited to both production sampling and maintenance inspections. Each insert is intended for repeated handling; the set format reduces the risk of misplacing individual items and keeps calibration loops easier to manage when the measuring chain requires scheduled checks.
