Gauge pin M323.688 — single precision measuring pin, 6.88 mm diameter, ±0.001 mm tolerance (Metav IndustryLine)

The Gauge pin M323.688 is a single precision measuring pin designed for end-dimension checks and inspection tasks in workshop and quality‑control settings.

• Workshop design for robust use
• Diameter 6.88 mm for end-size measurement
• Tolerance ±0.001 mm for high precision
• Length 50 mm made from special steel

Reliable accuracy for process control

The compact measuring pin offers a tolerance of ±0.001 mm, enabling high-confidence pass/fail checks and dimensional spot checks during production. Such fine accuracy reduces rework and limits scrap rates by making deviations immediately detectable; the specification is suited to gauging tasks where micrometric differences determine component acceptance. By combining a defined diameter with a stable length, the pin provides a repeatable reference that supports both bench inspection and fixture-based verification processes. Emphasis on measurable outcomes and process stability makes this tool a practical choice for quality‑driven operations.

Durable design that withstands workshop use

Constructed from special steel and specified as a workshop execution, the measuring pin balances toughness with surface integrity. The robust material choice resists wear from repeated seating and extraction, preserving the 6.88 mm diameter and the 50 mm usable shank over many cycles. A solid single‑piece geometry reduces the risk of deformation under normal handling and ensures consistent contact with mating bores and faces. This durability minimises downtime for replacement and supports a steady inspection rhythm on the shop floor, where tools must deliver performance without frequent adjustment.

Practical fit for quality inspection routines

Integration of the pin into standard inspection jigs or portable gauging sets is straightforward owing to its defined dimensions and compact form. The gauge pin serves well for end‑dimension verification, go/no‑go seating checks and dimensional benchmarking during set‑up. Its small footprint and precise specification assist in creating clear inspection protocols: fixed limits, documented measurement steps and traceable results. As a measured tool for routine checks, it contributes to faster decision making in production and supports documented quality control pathways that reduce ambiguity in acceptance criteria.
