Measuring inserts for Whitworth threads, 55° flank angle, 48-40 threads per inch, per pair, for thread micrometer

Description

Measuring insert for Whitworth threads, 55° flank angle is a thread micrometer accessory — either a setting ring (master gauge for zero-calibration of thread micrometers) or a measuring insert (the contact surface of the micrometer itself matched to the thread form). Both are essential for traceable thread pitch measurement on screws and nuts.

Setting rings are pre-cut threads at known pitch diameters — place it in the micrometer, zero it, then measure the workpiece thread. Measuring inserts have V-shaped or pointed contact surfaces that fit into the thread profile so the micrometer reads the pitch diameter directly. Hardened, ground surfaces; matched to specific thread pitch values.

Usage: for setting rings, place in the micrometer, read the zero value, adjust the micrometer if necessary; for measuring inserts, swap inserts to match the thread pitch and measure over the thread pitch line. Both require matching to a specific thread pitch and tolerance class.

Common applications: calibration of thread micrometers in calibration laboratories, traceable thread QC in manufacturing workshops, master-gauge-based zero verification chains, and educational applications for thread form instruction.

Features

• Measuring insert for Whitworth threads, 55° flank angle
• Hardened, ground reference surfaces for repeatable measurement
• Schut build quality
• Suitable for workshop QC, calibration labs and bench measurement applications
• ECONOMY LINE series
