• Diameter 4.37 mm for end‑measure checks
• Length 50 mm workshop version
• Supplied in protective transport box

Precision where measurement affects quality

A tolerance of ±0.001 mm places this gauge pin in the high‑precision segment for go/no‑go and end‑measurement tasks. The small 4.37 mm diameter offers accurate contact on narrow bores and small features, while the tight tolerance ensures high repeatability across inspection routines. For quality control, such reproducible readings reduce rework and support consistent acceptance criteria, making the component ideal where micrometric accuracy is required.

Durable design for everyday workshop use

Manufactured from special steel, the pin is specified as a workshop version, combining hardness and wear resistance to withstand frequent use. The 50 mm length gives sufficient reach for many end‑measure applications without compromising stiffness, and the low mass supports easy handling during inspection cycles. This balance of robustness and usability minimises operator fatigue and keeps measuring routines efficient on the shop floor.

Practical handling and storage for inspection workflows

Delivered in a protective transport box, the pin is ready for safe storage and secure transit between inspection stations. The compact format supports straightforward integration into bench tooling, fixture checks and assembly validation. The clearly identified SKU and GTIN allow fast replenishment in procurement systems, helping to maintain uninterrupted inspection supply chains and avoid costly downtime.

Where this gauge pin adds value

Typical applications include final dimension checks, fixture verification, small‑bore gauging and quality assurance in precision workshops. In these scenarios, the combination of a controlled material, exact diameter and micrometre‑level tolerance reduces measurement uncertainty and supports traceable inspection records. The result is fewer rejected parts and a more predictable production flow.
