Gauge pin M323.777 — 7.77 mm, ±0.001 mm, Metav IndustryLine

The Gauge pin M323.777 is a precision end‑measure designed for workshop inspection tasks and plug‑checking of bores in serial production.

• Precision tolerance ±0.001 mm
• Diameter 7.77 mm ground to size
• Length 50 mm for stable handling
• Special steel for improved wear resistance

Reliable accuracy for repeatable inspection results

The compact design delivers a clear production advantage: the ±0.001 mm tolerance ensures measurements that are suitable where micrometric reproducibility matters. This level of accuracy equates to one thousandth of a millimetre and supports tight fit and clearance checks in assembly and quality inspection. By reducing measurement uncertainty, the pin contributes to consistent part acceptance rates and fewer reworks on the shop floor.

Durable handling and stable support during measurement

Manufactured from special steel, the pin combines surface hardness with dimensional stability for frequent use in workshop environments. The 50 mm length provides a convenient grip and enough overhang to seat the pin securely in fixtures without sacrificing stiffness. The workshop configuration is optimised for everyday handling and resists typical wear mechanisms, which keeps maintenance intervals low and preserves the gauge form over time.

Practical use in production workflows and tool sets

As a single gauge pin, this item serves as an end‑measure for plug checks, alignment aids and go/no‑go verifications within fixtures and gauges. The small footprint makes it easy to integrate into test benches or measurement kits, while the ground 7.77 mm diameter supports accurate seating in cylindrical bores. The Metav IndustryLine designation signals a product intended for industrial use and straightforward interchangeability with common inspection routines.

FAQ

What level of precision does the gauge pin provide?
The gauge pin M323.777 is specified to ±0.001 mm, offering micrometric repeatability suitable for tight tolerance checks and fit verifications in production.

For which inspection tasks is this pin intended?
This plug‑type gauge is intended for end measurements, plug checks and alignment verification in fixtures and small‑bore inspections where a fixed, accurate reference is required.

What material is the pin made from and how does that affect wear?
The pin is made from special steel, chosen for dimensional stability and wear resistance; this supports longer service life under regular workshop use.

Is the diameter ground or finished for seating accuracy?
The diameter is ground to size at 7.77 mm to ensure reliable seating in cylindrical bores and minimise play during measurements.
