M323.494 gauge pin — Ø 4.94 mm, tolerance ±0.001 mm, 50 mm length (Metav IndustryLine)

The M323.494 gauge pin is a precision cylindrical test pin for fast verification of bore diameters and end‑measurement tasks in workshop and production environments.

• Precision Ø 4.94 mm, tolerance ±0.001 mm
• Length 50 mm for compact inspection tasks
• Workshop execution with robust special steel
• Ideal for repeatable bore verification

Improve first‑pass yield with sub‑micrometre repeatability

The M323.494 is engineered for high‑precision bore checks, offering a tight tolerance of ±0.001 mm on a nominal diameter of Ø 4.94 mm. This level of accuracy reduces false rejects and minimises rework because acceptance decisions are based on a measurable, verifiable reference rather than visual estimation. The result is a tangible productivity gain in inspection loops: quicker pass/fail verdicts, fewer downstream adjustments and more consistent quality records. The small mass and compact geometry support rapid handling during serial checks without compromising measurement repeatability.

Compact format that suits busy workshop workflows

With a length of 50 mm and a compact diameter, this test pin belongs to the micro range of precision measurement tools, making it particularly suited to space‑constrained environments such as jig and fixture stations or bench inspection benches. The special steel construction provides the stiffness required for repeatable contact and resists everyday workshop wear. The workshop configuration reflects pragmatic choices: robust finish, straightforward geometry and compatibility with common mandrels and holding fixtures used in production inspection.

Designed for clear, measurable control in production

The cylindrical probe functions as a direct end‑measurement reference: insert the pin into a bore to confirm dimensional conformity to nominal specifications. Because the dimension and tolerance are declared, the pin can be integrated into statistical process control routines and visual inspection charts as an objective reference. Its compact form facilitates quick interchange between gauges, enabling technicians to perform spot checks without disrupting throughput. The M323.494 therefore serves both as a handheld verification tool and as a standard for fixture‑based checks in repetitive manufacturing operations, contributing to tighter process control and lower scrap rates.
