U washer DIN 6340 AMF — Flat washer for M10, 10.5 mm bore

A U washer DIN 6340 AMF engineered to distribute clamping forces evenly in M10 bolted connections for industrial and workshop assembly applications.

• Compliant with DIN 6340 standard
• Suited for M10 bolted connections
• Bore diameter 10.5 mm for secure fit

Predictable fit and conformity for reliable assemblies

Conformity with DIN 6340 provides a predictable, standardised geometry that simplifies component selection and inventory management. The specification ensures interchangeability across production batches and replacement parts, reducing downtime caused by non‑matching components. The combination of standard compliance and clearly defined dimensions supports consistent mechanical behaviour under load and aids quality control procedures.

Secure load distribution with defined dimensions

The washer’s 10.5 mm bore aligns with M10 shaft tolerances while the 28 mm outer diameter increases contact area to distribute clamping forces over the joining surfaces. A thickness of 4 mm contributes to rigidity and reduces local deformation under torque. These dimensional characteristics translate into reduced surface marking and improved joint stability in repeated assembly cycles.

Practical use and supply reliability for industrial workflows

Designed for routine use in maintenance, machine assembly and fastening applications, this flat washer supports efficient workshop operation through straightforward compatibility with common fasteners. Sourced via Metav Werkzeuge, the product benefits from a secure supply chain and quality filtering at the Emmerich location, which helps ensure consistent availability and trusted origin for production and service parts.
