Precision where tight fits matter

The 4.23 mm diameter and an exceptional ±0.001 mm tolerance make this gauge pin a reliable reference for inspections where small clearances determine part performance. As a precision pin, it provides a stable datum for checking bore sizes, alignment seats and end measures; the narrow tolerance reduces uncertainty when comparing serial parts or verifying machining set‑ups. The careful machining of the shaft yields a consistently round contact surface, which supports reproducible results and simplifies pass/fail decisions during quality checks.

Robust workshop design for everyday use

Built as a workshop‑grade item from special steel, this test pin balances wear resistance with handling comfort for routine use. The 50 mm overall length gives sufficient reach for most bench and fixture checks while remaining compact enough for quick placement and removal. With a mass of approximately 0.007 kg, the pin is easy to handle and integrates smoothly into existing inspection workflows. Delivery in a protective transport case preserves surface integrity during storage and transit, reducing rework and extending service life.

Practical applications and handling tips

Intended for end‑measurements and plug verification, the pin is suitable for gauging bores, verifying alignment jigs and confirming finish dimensions on small components. When used as a reference mandrel, allow the part and gauge to stabilise thermally before measuring to avoid thermal expansion errors. Clean contact surfaces with a lint‑free cloth and light machine oil to maintain repeatability; avoid abrasive cleaners that could alter the shaft diameter. The compact form factor and tight tolerance make this precision component a valuable addition to inspection benches and assembly stations where dependable, repeatable checks speed up quality control.
