Test pin M323.A81 — single gauge pin, Ø 10.81 mm, length 50 mm (Metav IndustryLine)

The Test pin M323.A81 is a single, precision gauge pin designed for repeatable end‑dimension verification and fixture alignment in workshop environments.

• Workshop-grade construction
• Diameter Ø 10.81 mm precision
• Length 50 mm compact dimension
• Tolerance ±0.002 mm high accuracy

Repeatable accuracy for production control

The gauge pin is manufactured for consistent measurement performance with a declared tolerance of ±0.002 mm, ensuring tight interchangeability during go/no‑go checks and assembly setup. Such a fine tolerance reduces uncertainty in pass/fail decisions and supports statistically sound process control. The nominal diameter Ø 10.81 mm is produced to a defined size class so that pins can be used as master pieces for gauges, alignment dowels or end‑stop verification without frequent rework. Precision in this context means that repeat measurements under the same conditions give the same result, which directly lowers scrap rates and supports efficient quality assurance.

Compact design that fits workshop workflows

With a 50 mm length and a mass of approximately 0.1 kg, this compact gauge pin is classified in the Micro group (measurement range up to 100 mm), where rigidity and minimal bending are crucial. The short, stiff geometry aids handling by a single operator and suits tight fixturing and small‑part checks. Constructed in special steel, the component resists normal workshop wear while remaining easy to position in fixtures or gauge blocks. The workshop version finish emphasises practical durability: robust surfaces and a profile designed for rapid insertion and extraction during routine inspection tasks.

Traceability and system integration for dependable workflows

The M323.A81 is supplied with product identifiers for traceability and inventory control; the SKU and GTIN enable straightforward integration into inspection protocols and stock systems. As part of the Metav IndustryLine range, the pin complements a broader selection of metrology accessories and gauge components, simplifying procurement and replacement planning. Relying on standardised gauge pins like this one supports clear maintenance intervals and predictable calibration schedules, which together strengthen overall process reliability and reduce downtime.
