Reliable accuracy for small‑bore inspection

Small‑diameter inspection demands stability and a defined contact geometry. This gauge pin provides a 3.43 mm nominal diameter with a very fine ±0.001 mm positional tolerance, delivering the repeatability required for gauging tight bores and verifying end dimensions. The controlled tolerance reduces variation when checking mating parts or setting up fixtures, which shortens inspection cycles and lowers the risk of part rejection. In practice, this means more consistent pass/fail decisions and fewer interruptions on the shopfloor.

Built for the workshop — durability without compromise

Manufactured in special steel and labelled as a workshop execution, the pin resists everyday handling and contact wear while keeping measuring geometry stable. Its 50 mm length gives enough reach for many small assemblies and fixture adjustments without sacrificing rigidity. Supplied in a protective case for transport, the tool stays protected between tasks and during storage, reducing the chance of nicks or contamination that can affect measurement integrity. The compact mass and balanced design aid rapid handling during repetitive inspection sequences.

Practical use and interpretation of measurements

Gauge pins of this size sit in the micro range for precision work on small components and assemblies. They are commonly used for bore validation, alignment of jigs and fixturing, and as master plugs in quick go/no‑go checks. The smooth, calibrated contact surface facilitates consistent engagement and minimises measurement scatter due to surface irregularities. For users not specialised in metrology, a gauge pin provides a direct physical reference that simplifies dimensional assessment compared with indirect measurement techniques, thereby improving decision speed and traceability in quality control processes.
