M323.178 gauge pin — 1.78 mm, ±0.001 mm, 50 mm length (Metav IndustryLine)

M323.178 is a single gauge pin designed for precise dimensional checks in inspection benches and jig setups; suitable for pinpointing bore diameters and end-measurements in production control.

• ±0.001 mm tolerance for high repeatability
• 1.78 mm diameter for fine bore inspection
• Compact 50 mm length for confined fixtures

Precision that stabilises quality control

The core advantage of this gauge pin lies in its tolerance of ±0.001 mm, which supports highly repeatable inspection cycles and reduces uncertainty in pass/fail decisions. Manufactured from special steel, the cylindrical pin provides consistent contact geometry and wear resistance, so measurement variability from the probe–part interface is minimised. The narrow 1.78 mm diameter and 50 mm functional length make the item particularly suited to small-bore verification and end-measure checks where access is limited but dimensional certainty remains critical. This performance focus delivers measurable productivity gains in serial inspection and first-article verification.

Robust workshop design for everyday use

Built as a workshop version, the pin balances precision with handling resilience required on production floors. The compact weight and solid material ensure easy insertion into jigs and gauges without excessive flex, while the surface finish maintains low friction for repeatable seating. Supplied in a protective transport box, the item can be carried between inspection stations without risk of accidental damage, preserving the integrity of the measuring face. These design choices reduce downtime related to replacement and support steady throughput in machining and assembly operations.

Practical benefits and traceability for inspection routines

Small dimensions and a fine tolerance make the component an ideal reference tool for quick go/no‑go checks and for setting up measuring fixtures where micrometre-level control matters. The pin’s geometry suits applications such as bore sizing, alignment dowelling and end-stop verification; its workshop-grade build allows direct integration into existing hard-gauges and test benches. For procurement, the clear specification and trade-grade SKU aid inventory control and repeat ordering, while the Metav commitment to accessible precision provides a dependable supply chain for small and large workshops alike.
