M323.458 gauge pin — 4.58 mm, ±0.001 mm, 50 mm (Metav IndustryLine)

The M323.458 gauge pin is a workshop-grade measuring pin designed for exact verification of small bores and end dimensions in inspection and setup tasks.

• Workshop-grade design for everyday inspection
• Diameter 4.58 mm with ±0.001 mm tolerance
• 50 mm overall length for deep bore checking
• Made from high-grade special steel

Accuracy that secures measurement decisions

The pin delivers industry-grade accuracy with a declared ±0.001 mm dimensional tolerance on a nominal 4.58 mm diameter, which reduces ambiguity in go/no-go inspections and end-dimension checks. Such precision minimises downstream rework and supports consistent pass/fail decisions during incoming inspection and in-process control. The tight tolerance is particularly relevant where cumulative tolerances in assemblies are critical; the result is improved repeatability and reliable verification of mating components.

Built for workshop use — robust and compact

Presented in a workshop-grade execution, the measuring pin is manufactured from special steel to balance hardness and toughness for everyday handling. The 50 mm overall length provides sufficient reach for moderate-depth bores while remaining compact for storage and rapid handling. The compact dimensions make the pin suitable for bench inspection, fixture set-up and quick comparative checks, offering a durable tool that resists deformation under normal workshop use and maintains its dimensional integrity over repeated cycles.

Practical use and integration into inspection workflows

As a single pin, it is ideal for direct plug checks, end-measurement references and transfer measurements when setting gauges or fixtures. The measuring pin simplifies verification of bore sizes and end masses by providing a physically precise reference that can be used with micrometres, gauges or optical comparators. For applications that demand defined limits, the pin supports rapid visual or tactile assessment and can be incorporated into measurement routines to document conformity or to adjust processes before parts leave the workbench.

FAQ

What application is this gauge pin suited for?
The M323.458 gauge pin from Metav IndustryLine is suited for precise plug checks, end-dimension verification and setup tasks where a 4.58 mm reference is required.

How precise is the measuring pin for inspection use?
Precision is declared as ±0.001 mm for the 4.58 mm diameter, enabling tight tolerance assessments during routine inspection and assembly control.

Can the pin be used for deep bores?
With a 50 mm overall length the pin is suitable for moderate-depth bores and typical workshop checks; for much deeper bores longer pins or specialised tooling may be required.

What material is the pin made from and why does it matter?
The pin is made from special steel, providing a balance of hardness and toughness that helps maintain dimensional stability under regular workshop conditions.

Is the item supplied as a single unit or in sets?
This product is supplied as a single measuring pin (single unit), intended for individual use in inspection and setup processes.
