• Diameter 1.71 mm special steel
• Length 50 mm for bore penetration
• Delivered in protective transport case

Reduce inspection uncertainty with sub‑micron accuracy

The core advantage of this inspection pin is its ±0.001 mm nominal tolerance, which positions it in the class of high‑precision reference pins suitable for fine inspection tasks. When used as a go/no‑go reference or as a fixed‑dimension master, the extremely low deviation helps to reduce rejects and rework by giving a clear, reproducible check against drawing limits. The compact diameter of 1.71 mm combined with the tight tolerance makes the pin particularly valuable where small bores or precision fit checks must be performed without ambiguity.

Designed for small‑bore and end‑measure applications

With a 50 mm shaft length, the pin reaches into deeper bores and recesses where short probes cannot. The single‑piece design and workshop specification ensure the pin behaves predictably during insertion and withdrawal, supporting consistent measurement routines. As an end‑measurement tool it serves well in production sampling, first‑article inspection and assembly checks, enabling straightforward verification of hole diameters, alignments and simple positional fits on small components.

Robust material and practical handling in production

Manufactured from special steel, the pin resists routine wear and preserves dimensional stability under normal workshop conditions. The modest mass (approx. 0.004 kg) makes it easy to manoeuvre while the solid construction reduces the risk of bending during use. Delivered in a protective transport case, the item is protected in transit and on the bench, which helps to maintain the reference dimension and prolong service life even when stored alongside other tools.

Practical integration into quality workflows

As a single, calibrated reference element for end measurements, the pin complements gauge blocks, plug gauges and optical inspection routines. Its simple geometry keeps handling intuitive for operators, while the precision tolerance feeds directly into statistical process control and acceptance sampling criteria. For customers seeking repeatability in small‑bore verification, this inspection pin offers a compact, low‑effort method to standardise checks across shifts and operators.
