Single gauging pin M323.425 – 4.25 mm, ±0.001 mm accuracy

A Single gauging pin 4.25 mm designed for precision end‑measure checks and dimensional verification in workshop and inspection environments

• Workshop version for robust everyday use
• Diameter 4.25 mm with ±0.001 mm accuracy
• 50 mm overall length for reach and stability

Proven accuracy that speeds up inspection

The gauging pin delivers a tolerance of ±0.001 mm, allowing concise pass/fail decisions where tight end‑measure control is required. Such fine accuracy reduces rework and inspection time by giving repeatable reference dimensions for plug gauges, fixture set‑up and comparative checks. The nominal 4.25 mm diameter is manufactured to strict roundness and size limits, which helps maintain consistent contact geometry when inserted into bores or applied against datum faces. This level of performance is particularly effective in production runs where traceable, repeatable checks underpin quality control procedures.

Robust design optimised for workshop conditions

Constructed from special steel, the pin is specified as a workshop version for everyday handling and resistance to wear. The 50 mm overall length provides additional reach while maintaining stability during measurement tasks, and the low mass supports quick manual manipulation with minimal deflection. The material choice balances hardness and toughness so that the gauge retains its dimension under typical handling and cleaning routines without excessive brittleness. The compact form factor and durable finish make this pin suitable for bench checking and portable inspection kits.

Practical handling and typical applications

The single pin is ideal for end‑measure and reference tasks such as checking bore entrances, verifying fixture positions and confirming small feature diameters in assembled parts. In metrology labs and workshops it serves as a simple, reliable reference when set against calibrated master gauges or integrated into comparative setups. The compact size aids access to confined features, while the pronounced accuracy supports quality documentation and dimensional reporting. For repeat operations, the pin’s consistent geometry improves measurement repeatability and shortens inspection cycles.
