• Hardened special steel construction
• Compact cross-section 35 x 9 mm
• Nominal length 400 mm, stable reference

Stable, standardised reference for inspection and calibration

The end gauge 400 mm is manufactured to DIN EN ISO 3650 and supplied as a Grade 1 length standard, making it suitable as a reference part for comparative checks and routine verification. Grade 1 classification signals a high level of dimensional fidelity under the applicable standard; the result is a reliable benchmark for checking measuring instruments, setting up gauging devices or validating production jigs. The clearly defined nominal length supports traceable documentation and reproducible inspection procedures in a production environment.

Medium-range design that balances reach and rigidity

This length falls into the medium measurement class (300–500 mm), which is the practical sweet spot for many tooling and assembly tasks. At 400 mm the gauge offers greater reach than short workshop references while remaining sufficiently stiff to avoid undue deflection. The compact 35 x 9 mm cross‑section reduces bending without adding excessive mass, so handling and fixture placement remain straightforward during on‑bench or bench‑mounted checks. The geometry thus improves repeatability for components such as fixtures, housings and medium-sized machined parts.

Hardened construction for long service life and low uncertainty

Made from hardened special steel, the bar resists wear and surface damage that would otherwise degrade measurement certainty. A robust surface and thermal stability reduce the drift that can occur with softer materials, so intervals between verification cycles can be optimised. The construction reduces the influence of contact marks and abrasion on the reference faces, which in turn helps to maintain a low measurement uncertainty during comparative use in production or quality departments.

Practical integration into quality processes

The gauge integrates directly into standard workshop workflows as a fixed reference for caliper checks, fixture set‑up and routine inspection cycles. The solid construction and clear standard designation simplify internal documentation: the bar can be recorded as the reference for in‑house checks and routine acceptance tests. When used alongside established control plans, the reference bar helps to accelerate go/no‑go decisions and supports reproducible measurement outcomes across shifts and operators.
