Inspection pin M323.390 — workshop inspection pin, 3.90 mm, ±0.001 mm

A workshop-grade inspection pin M323.390 designed for precise end-measure verification and repeatable dimensional checks in production and control environments.

• Micron accuracy ±0.001 mm
• Diameter precisely 3.90 mm
• 50 mm working length
• Workshop-grade special steel

Micron-level verification for consistent quality control

The inspection pin delivers ±0.001 mm nominal tolerance on a 3.90 mm diameter, which corresponds to sub-micron repeatability suitable for tight production tolerances. Such precision reduces sorting and rework times by providing an objective reference for end-measure checks and go/no-go evaluations. The compact geometry and defined length support stable seating in fixtures and measurement stands, improving measurement throughput while maintaining clear traceability of results. Using a hardened, dimensionally stable reference like this ensures that inspection routines remain efficient and reproducible across batches.

Engineered for tough workshop use and long service life

Built as a workshop-grade component from special steel, the pin balances surface resilience with dimensional stability under regular handling. The 50 mm length provides sufficient engagement for many end-measure tasks while keeping the tool easy to handle and store. A low mass construction contributes to reduced wear on mating surfaces during frequent checks. The robust finish and material selection mean fewer replacements and lower life‑cycle costs compared with softer, untreated pins — a pragmatic advantage for busy production benches and quality departments that require dependable everyday tools.

Practical integration into inspection routines and stock systems

The inspection pin is referenced by SKU M323.390 and GTIN 4061905055515, simplifying inventory management and procurement. As a dedicated end-measure reference, it complements plug gauges and reference blocks within a measurement kit and fits standard holders and fixtures used for end-face verification. The product data does not specify a delivered calibration certificate; calibration status is therefore not stated in the available information. For traceability planning, the clear numeric specification (diameter, length, tolerance) supports inclusion in control plans and inspection documentation without ambiguity.
