OnlyScrews Pitch Gauge for Metric Screws

OnlyScrews Metric Screw Pitch Gauge is a precision measuring tool used to accurately identify the thread pitch of metric screws and bolts. Made from hardened steel with clearly marked metric pitch sizes, it allows quick and reliable verification of screw threads without damaging the fastener. Ideal for workshops, maintenance, machining, quality inspection, and hardware applications.

How to Use the Metric Pitch Gauge:

1. Select the screw or bolt whose thread pitch needs to be identified.
2. Open the pitch gauge leaves and choose a leaf with a matching metric value.
3. Place the gauge teeth against the screw threads.
4. Check the fit – the correct pitch will sit perfectly in the threads with no gaps or overlap.
5. Read the marked value on the gauge leaf to determine the thread pitch in millimeters.

Applications:

• Identifying unknown metric screw and bolt pitches
• Verifying thread specifications during manufacturing and machining
• Maintenance and repair work
• Hardware stores, tool rooms, and quality-control inspection
