M323.258 Test Pin – 2.58 mm diameter, ±0.001 mm, workshop version (Metav IndustryLine)

The M323.258 Test Pin is a single high-precision gauge pin for bore and fit verification in workshop inspection and production control.

• Diameter precisely 2.58 mm ±0.001 mm
• 50 mm hardened shank for stable handling
• Special steel for long service life
• Workshop version with transport case

Consistent accuracy that reduces rework and inspection time

A tight ±0.001 mm tolerance on a 2.58 mm diameter delivers a measurable improvement in pass/fail decisions during incoming inspection and in-process checks. This level of precision functions as a reliable reference for small-bore verification and assembly gauges, reducing the need for repeat measurements and lowering scrap rates. The specification is expressed in engineering terms so that tolerancing aligns directly with inspection criteria and measurement plans.

Robust design for demanding workshop environments

The 50 mm shank provides comfortable handling and stable seating in fixtures, while the special steel construction resists wear during repeated use. As a workshop version, the pin is designed for practical daily handling rather than delicate laboratory use, so measurement repeatability is retained across shift changes. The low mass and compact form facilitate quick interchange in gauge assemblies and minimise the impact on manual handling ergonomics.

Streamlined integration into quality workflows

Delivered as a single inspection pin with a clear article reference, the component fits naturally into go/no-go setups, gauge blocks and precision jigs. Using a standardised gauge pin such as this simplifies ordering and stock control, enabling consistent measurement procedures across workstations. Procurement from a single supplier reduces lead-time variability and supports stable inspection routines in production and maintenance environments.

FAQ

Is the M323.258 suitable for tight bore verification?
The M323.258 test pin is specified at 2.58 mm with a ±0.001 mm tolerance, making it suitable for tight-bore checks and precision fits where sub-millimetre accuracy is required.

What material is used for the pin?
The pin is manufactured from special steel, chosen for wear resistance and stability during repeated measurement cycles.

How is the item supplied?
The product is supplied as a single test pin in a workshop-ready configuration and is delivered with transport protection.

For which applications is this test pin intended?
The pin is intended for bore inspection, fit verification and use in gauge assemblies or jigs where a precise reference diameter is required.

Is a calibration certificate included?
The product data does not specify a calibration certificate; the item is described as a single inspection pin without an explicit calibration statement.
