Gauge pin M323.291 — 2.91 mm diameter, ±0.001 mm tolerance

A gauge pin M323.291 designed for precision end measurements and fixture verification in workshop and inspection environments.

• Diameter 2.91 mm, high-precision fit
• Tolerance ±0.001 mm for repeatable checks
• Length 50 mm for fixture compatibility
• Workshop version, robust finish

Keep production accurate with measurable precision

The primary advantage of this single gauge pin is its tight nominal control: a 2.91 mm diameter manufactured to ±0.001 mm guarantees dimensional consistency for small-bore checks and plug-fitting tasks. Such precision reduces ambiguity in pass/fail decisions during incoming inspection and in-process checks, so measurement results can be relied on when recording tolerances or adjusting fixtures. The narrow tolerance also shortens decision times on the shop floor and supports traceable quality control when repeatability matters.

Robust shop-floor design reduces handling risks

Specified as a Workshop version, the pin combines a compact form with a finish and material choice suited to everyday use. Manufactured from special steel, the pin offers corrosion resistance and wear performance appropriate for regular insertion into bores and jigs without rapid surface degradation. The 50 mm shank gives sufficient engagement for many fixture geometries while remaining easy to handle and position with standard tweezers or collet holders. The result is sustained service life and fewer replacements — an efficiency gain in both routine metrology and fixture verification.

Practical integration into inspection workflows

Small components, gauges and end-measure parts demand straightforward handling. The M323.291 is sized to work with common pin blocks, insertion gauges and manual checking routines, enabling quick comparison checks and assembly gauging. For batch inspection, the pin’s consistent dimensions aid in establishing baseline measurements and can be used as a reference when comparing manufactured parts against drawing data. Where traceable records are required, the pin’s repeatability supports stable measurement series and clearer statistical process control entries.
