Gauge pin set M318.823 — 21-piece, 3.00–4.00 mm, 0.05 mm steps

The gauge pin set for fast, repeatable verification of hole diameters in production and quality control, suitable for workshop and inspection use

• 21-piece set covering 3.00–4.00 mm in 0.05 mm steps
• Pins 70 mm length for deep bore verification
• Special steel for wear resistance and stability
• Fine 0.05 mm graduation for repeatable checks

Consistent dimensional checks with clear graduations

The 21-piece set provides continuous increments across a narrow diameter band, making it ideal where small tolerance steps are required. Each pin advances by 0.05 mm, a graduation that supports consistent go/no‑go style checks and stepwise narrowing of bore acceptance. For quality managers and shop‑floor inspectors this means fewer measurement cycles to locate out‑of‑tolerance features and faster decision making. The concise diameter coverage of 3.00–4.00 mm reduces handling complexity while preserving the diagnostic detail required for precision components.

Robust pins for everyday shop use

Constructed from special steel, the pins combine surface durability with dimensional stability during repeated seating and removal. The 70 mm length is beneficial when verifying deeper bores or through‑holes, offering access beyond what short pins permit without compromising rigidity. The set form factor keeps the assortment organised and accelerates part changeover. Users will notice reduced rework and more predictable inspection times thanks to the material choice and consistent pin geometry.

Practical benefits for inspection workflows

Adopting this set helps to streamline routine inspections: the fine 0.05 mm stepping supports close tolerance screening, while the compact diameter range allows quick narrowing of suspect features. The construction and finish minimise burr transfer and sticking, which keeps throughput steady. Traceability is supported by the clear marking and the product identifier M318.823, which simplifies calibration records and stock management for the quality department.
