Repeatable accuracy where it matters

Precision is the primary value of this inspection pin. With a specified tolerance of ±0.001 mm, the pin supports reliable go/no‑go and comparative checks that reduce uncertainty during incoming inspection or in‑process control. The compact diameter of 6.21 mm and moderate 50 mm length make the item suitable for tight bores and confined measuring spaces, while the fine tolerance helps to detect minute deviations that would otherwise affect assembly or function. The technical specification is ideal for workshop applications where small form‑factor precision tools are required.

Built for workshop use and sustained service life

The workshop version is engineered for everyday inspection routines. Manufactured from special steel, the shaft offers a balance of hardness and toughness that resists rapid wear under repeated contact inspections. The single‑piece supply simplifies inventory selection for toolrooms and gauges, and delivery in a protective transport case preserves the ground surface and concentricity during storage and transit. Together, these attributes lower the total cost of ownership by extending service intervals and maintaining measurement integrity between checks.

Integrates cleanly into quality control processes

As a precision inspection element, this gauge pin fits directly into established quality workflows: setting ring gauges, verifying bore diameters, and confirming fit tolerances on assemblies. The compact format supports rapid interchange and reduces handling time on the shop floor, contributing to faster inspection cycles and more consistent acceptance decisions. For those tracking inventory or referencing product data, the item is listed under SKU M323.621 and is supplied as an individual gauge pin suitable for routine dimensional control tasks.
