Gauge pin Ø 4.78 mm, ±0.001 mm — 50 mm single gauge pin (Metav IndustryLine)

A gauge pin Ø 4.78 mm, 50 mm designed for precise end‑measurements and calibration tasks in workshop and production metrology

• Workshop version for robust daily use
• Tolerance ±0.001 mm for sub‑micron checks
• Diameter 4.78 mm, precision fit
• Compact 50 mm length for small components

Stabilise quality control with sub‑micron repeatability

The workshop‑grade pin delivers a tolerance of ±0.001 mm, which translates into consistent go/no‑go checks and reliable end‑measurements across production batches. Such a fine tolerance ensures that critical dimensions are verified with minimal ambiguity, reducing rework and improving first‑pass yields. The specification is particularly relevant where traceable, repeatable checks decide whether a part continues down the process chain or is rejected.

Compact format optimised for fine components

Classified in the micro measurement range, the short 50 mm length and 4.78 mm diameter are ideal for precision work on small assemblies, delicate housings and micromechanical parts. The compact form reduces lever‑induced bending during handling, improving positional stability and measurement reproducibility. For bench or fixture use, the small footprint allows close packing of inspection points without sacrificing accessibility.

Built for workshop durability and practical handling

Constructed from special steel, the pin is made to withstand frequent use in an industrial environment while retaining its measuring geometry. The workshop configuration emphasises robustness without compromising accuracy, so routine inspection cycles remain fast and dependable. The material choice balances wear resistance with machinability, supporting long service life under normal inspection loads.

Clear specification for integration into inspection routines

The item is supplied as a single gauge pin with a defined nominal diameter of 4.78 mm and a nominal length of 50 mm, enabling straightforward substitution into existing gauging fixtures and comparison jigs. The precise tolerance assists in designing limit checks and inspection plans, while the compact dimensions simplify storage and handling within a standard metrology toolset. For documentation and inventory purposes, the product is listed under SKU M323.478 and GTIN 4061905057205.
