Lumatic Thread Identification Plate

It identifies common Metric, UNF/ANF, BSW, NPT, BSF, and BSPT thread sizes, covering a broad range of applications.

Simply compare the thread you need to identify with the markings on the plate. Align the thread with the listed sizes until you find a match for both the diameter and the pitch.

The plate covers common industrial and mechanical thread sizes. For extremely fine, specialized, or custom threads, a dedicated thread gauge might be more appropriate.

It is made from durable materials designed for workshop use. However, like any tool, it should be cared for properly to ensure longevity of the markings.

No, this plate is designed solely for identifying thread size (diameter and pitch), not for measuring depth or other dimensions.

This product is usually dispatched within 2 working days.

Clean the plate with a dry or slightly damp cloth. Avoid abrasive cleaners or solvents.

Ensure the thread itself is clean and free of debris. Hold the plate at a different angle or in better lighting. If the thread is worn or damaged, it may be difficult to identify accurately.

Clean the plate with a soft, dry cloth. If dirt is stubborn, use a slightly damp cloth and dry immediately. Avoid harsh chemicals.

Double-check that you are comparing the correct aspect of the thread (pitch and diameter). The plate covers common sizes; your thread might be a less common or specialized variant. Consider using a thread gauge for precision if necessary.
