Flange CFN1219 (DIN 6331) — 25 mm, M12 x 1.75 — Vertex

A Flange CFN1219 manufactured to DIN 6331 for standardised attachment in clamping and tooling assemblies

• DIN 6331 compliant flange
• M12 x 1.75 mm threaded connection
• 25 mm outer diameter, compact 18 mm height
• Lightweight: 0.03 kg for reduced spindle load

Standardised fit for predictable assembly

Manufactured to the DIN 6331 guideline, this flange provides a standardised interface that simplifies part selection and reduces assembly errors. The M12 x 1.75 mm threaded connection gives a common metric fit that is widely supported across tooling systems, allowing rapid replacement and straightforward interchangeability. With a clearly specified 25 mm diameter, the component matches typical clamping interfaces used in industrial fixtures and modular tooling, which supports smoother integration into existing production jigs and holders.

Compact form factor that eases machine load

The flange's compact dimensions — 18 mm height and a mass of only 0.03 kg — translate into tangible performance advantages. A lower rotating mass reduces inertial load on spindles and rotary couplings, which can improve balancing and minimise wear on bearings over time. The space-saving profile also helps when working in constrained tool pockets or on multi-component assemblies, enabling denser tool layouts without compromising mechanical stability.

Clear specifications for confident procurement

Thread and dimensional details are stated visibly to remove ambiguity: the metric thread follows the common pitch and diameter of M12 x 1.75 mm, while external sizing is standardised to facilitate compatibility checks. For non-specialist users, the thread designation means a 12 mm nominal diameter with a 1.75 mm thread pitch, a specification commonly used in fastening and clamping components. Such clarity supports procurement decisions and reduces the need for custom adaptors or additional machining.
