• Diameter 12.91 mm for end measurements
• Tolerance ±0.002 mm for repeatable results
• Delivered in transport box for safe handling

Precision where measurement consistency matters

The plug gauge offers a finely controlled fit for end‑measurements thanks to its ±0.002 mm tolerance, ensuring consistent readings across repeat checks. As a single‑piece measuring element with a nominal diameter of 12.91 mm, it reduces uncertainty when verifying bore sizes, locating holes or checking assembly interfaces. The measurable benefit is fewer rework cycles and clearer go/no‑go decisions in quality control processes, deriving efficiency gains through predictable, comparable data.

Built for workshop use and secure handling

Manufactured in special steel and specified as a workshop‑grade item, the gauge pin combines surface hardness with the toughness required for everyday handling. The 50 mm overall length provides a stable engagement in fixturing and clamping applications without excessive overhang, supporting repeatable seating and alignment. For transport and on‑site protection the item is supplied in a transport box, which reduces the risk of damage during handling and keeps the measuring face free from contamination between uses.

Practical applications and suitable measurement class

This measuring plug belongs to the micro range (10–100 mm), making it ideal for precision tasks in toolmaking, fixture setup and component inspection where small diameters and tight fits are common. Typical uses include end‑measurement verification, fixture pinning, hole gauge checks and assembly verification. The compact geometry minimises bending and ensures a reliable reference when used as a locating element or for transfer checks in serial production environments.
