• Length 50 mm for stable reference measurements
• Special steel workshop design
• Delivered in protective case for transport

Accuracy for reference measurements

A compact reference element with a 4.77 mm functional diameter and a guaranteed ±0.001 mm tolerance, the gauge pin provides a stable, repeatable datum for final size checks and plug‑go gauging. The fine tolerance class makes this pin suitable where small deviations affect fit or assembly quality; using a hardened special steel shaft reduces wear and preserves the measured end‑size over many cycles. As a dedicated test pin, it serves as a certified reference for production sampling, setting limits on machining acceptability and supporting traceable quality routines.

Durability and workshop readiness

Designed as a workshop version, the pin balances surface hardness with corrosion resistance to withstand routine handling. The length of 50 mm gives sufficient engagement for secure seating in jigs and fixtures while keeping the overall mass low for easy handling; the listed weight of 0.01 kg confirms its manoeuvrability. Delivery in a protective case ensures safe transport between inspection benches and reduces the risk of damage or contamination before use. These mechanical choices translate into lower replacement frequency and consistent inspection throughput in daily shopfloor operations.

Practical integration into inspection routines

As a precision test element, the pin is optimised for end‑size and reference checks on components, quick verification with micrometre stands, and as a master for comparative measuring devices. The compact geometry supports fast changeovers and repeatable positioning in measuring fixtures, which helps to reduce cycle times and rework rates. Where small clearances and press fits determine product function, the repeatability delivered by this pin improves process control and provides a verifiable basis for acceptance decisions in production and quality assurance.
