Custom Go / No-Go Pi Tape® Diameter Tapes are precision inspection tools designed for fast pass/fail verification of cylindrical parts. Manufactured to your exact specifications, these tapes provide reliable, repeatable measurements for quality control environments where tolerance matters.
Go / No-Go tapes are used to quickly confirm whether a part falls within an acceptable diameter range—without the need to record exact measurements.
This makes them ideal for high-volume inspection and production floor use
Our custom made Go/No-Go tapes may have one or more sets of A B C dimensions on one tape. Anytime “0” line falls between A B C lines, part is within tolerance. The minimum diameter distance between lines is .004″ (.12mm).
Each Go / No-Go tape is manufactured to order based on your requirements:
– Imperial Tapes
The standard diameter inch Go/No-Go tape gage member width is 1/4″. We also offer tapes with gage member widths of 1/8″, 3/16″, 3/8″ or 1/2″. The standard thickness of the material is .010″ on most sizes.
– Metric Tapes
The standard metric Go/No-Go diameter tape gage member width is 6.35mm. We also offer tapes with gage member widths of 4.76mm, 9.53mm or 12.70mm. The standard thickness of the material is 0.25mm on most sizes.
All Pi Tape® Go / No-Go tapes are manufactured using certified standards and precision processes developed for aerospace, industrial, and metrology applications. Each tape is calibrated for direct diameter readings.
Every Pi Tape® precision measuring tape includes a Calibration Report with results traceable through NIST to the International System of Units (SI).
