Insize Measuring Tips for Screw Thread Micrometre deliver precise contact with thread flanks, helping to produce repeatable readings. That reassurance reduces guesswork for machinists and restorers inspecting imperial-thread components. Are these tips the right match for work that relies on 24–18 TPI pitches?
⚡ At a Glance
- • Measuring Accuracy: Consistent flank contact tailored to repeatable thread readings
- • Best for: Machinists and inspectors checking imperial Whitworth threads
- • Not ideal for: Work that uses metric thread forms or non-Whitworth profiles
Tips match the Whitworth thread form with a 55° flank angle and are intended for imperial-thread measurement. Coverage includes pitches commonly listed between 24 and 18 threads per inch.
Reliable seating on thread flanks – with a 55° Whitworth profile
The 55° flank angle corresponds to the Whitworth thread geometry specified in the description, so tip contact aligns with the intended thread form. Correct flank engagement helps transfer the micrometre anvil contact precisely across the thread.
Accurate seating reduces measurement scatter and improves repeatability when checking thread diameters. Particularly useful when comparing samples against gauges or during quality checks.
Supports common imperial pitches – thanks to 24–18 TPI coverage
Pitch range stated as 24–18 threads per inch, matching a selection of Whitworth fine and standard imperial pitches. Tips are designed to correspond to those TPI specifications for direct comparison.
Quick identification and verification of components that use those imperial pitches makes inspection faster. Handy for maintenance and restoration of older machines that use imperial fasteners.
Suitable for international sourcing considerations – with imported-item notes
Description warns that international items may be sold from abroad and can differ from local versions, including fit, age ratings, labelling or instructions. Such differences can affect compatibility or user information.
Check seller details and supplied instructions when ordering from overseas sources to confirm fit and labelling. Doing so avoids surprises and ensures the tips match workshop requirements.
