Gauge pin M323.477 — Precision test pin, 4.77 mm, ±0.001 mm

A gauge pin M323.477 designed for fast end‑dimension checking and fixture set‑up in workshop metrology.

• Gauge pin 4.77 mm with ±0.001 mm tolerance
• 50 mm overall length for deep reference points
• Workshop version, rugged for daily use
• Supplied in transport case for secure storage

High‑precision reference for routine inspection

The gauge pin provides a consistently accurate datum for end‑size verification, with a nominal diameter of 4.77 mm and a declared tolerance of ±0.001 mm. This level of control places the pin in the high‑precision class of handheld reference tools and makes it suitable for gauging fits, verifying bores and checking pin seats. The compact shape and the 50 mm length allow access into deep reference points while maintaining sufficient rigidity for reproducible measurements. The precision statement is meaningful: the tight tolerance reduces rework and inspection time by cutting uncertainty in repeat checks.

Robust workshop design for everyday use

Manufactured in special steel and specified as a workshop version, the pin tolerates regular handling typical on production floors. The material choice balances wear resistance with stable dimensional behaviour; when used as a reference pin in fixtures or as a go/no‑go check, the construction ensures longevity under cyclical use. The practical geometry facilitates quick alignment, and the modest weight (0.01 kg) minimises inertia during manual positioning. This combination supports efficient inspection routines and lower downtime between checks.

Practical handling, transport and storage

Delivered in a transport case, the pin remains protected during storage and transit, reducing the risk of nicks that would compromise accuracy. The single‑piece format makes it simple to integrate into existing inspection sets or toolboxes. For batch checks, the straightforward handling shortens cycle times; for precision set‑up tasks, the compact form factor enables easy placement in fixtures. The SKU and trace data allow clear inventory tracking for quality documentation.

Typical applications and measurement context

Use the test pin for end‑dimension checks, fixture zeroing, plug verification and reference alignment in mechanical engineering and metalwork. The combination of 4.77 mm diameter, tight ±0.001 mm tolerance and a 50 mm length suits small‑bore verification, alignment of mating parts and set‑up tasks where a reliable datum reduces iterative adjustment. The pin is also useful in assembly and quality control where reproducible reference points shorten inspection protocols and support consistent production quality.
