U-washer DIN 6340 for M24 screws (AMF) — 25 mm bore, 60 mm OD

The U-washer DIN 6340 by AMF is a flat fastening washer engineered for use with M24 bolts in industrial and structural applications, providing standardised bearing and improved joint stability.

• Conforms to DIN 6340 standard
• 25 mm bore for precise bolt fit
• 60 mm outer diameter for load distribution
• 8 mm thickness for robust clamping

Consistent fastening through standard compliance

Conformity with DIN 6340 ensures interchangeability and uniform performance across production batches and suppliers. This standardised specification reduces uncertainty during procurement and assembly, as the washer's bore and form factor match established bolt sizes and seating geometries. The reliance on recognised norms supports quality assurance processes and simplifies documentation for audits and maintenance schedules.

Improved joint security via larger bearing area

A 60 mm outer diameter increases the bearing surface beneath the bolt head or nut, which reduces contact pressure and helps prevent material indentation on softer components. Combined with the 8 mm thickness, the washer delivers a stiffer clamp pack, limiting elastic compression under load. This results in more predictable preload retention and fewer loosening events in dynamic or vibrating environments, thereby supporting long-term joint integrity.

Accurate fit and reduced assembly time

The 25 mm inner bore is matched to M24 thread major dimensions, enabling a snug, concentric fit that aids rapid alignment during installation. The simple geometry of the ring-shaped washer streamlines automated or manual assembly, reducing orientation checks and handling time. Where repetitive fastening operations are performed, this predictability translates into measurable process efficiency gains and lower rework rates.

Suitable applications and compatibility notes

Designed primarily for standard industrial fastening tasks, the washer is suitable wherever M24 bolts are specified and a broad contact area is required for load distribution. The component is appropriate for structural connections, machine assembly, and heavy-duty fixtures that demand consistent clamp behaviour. For material-specific recommendations or to confirm compatibility with particular substrates, technical consultation is available via Metav Werkzeuge to ensure the correct selection for each application.

FAQ

What standard does this washer comply with?
The washer conforms to DIN 6340, which defines dimensions and form for this type of flat washer, ensuring reliable interchangeability.

Is this washer compatible with M24 bolts?
Yes — the washer is specified for M24 bolt compatibility, with a 25 mm bore designed for precise seating of the bolt shank.

What are the key dimensions to check when specifying this washer?
Important dimensions are the bore 25 mm, outer diameter 60 mm, and thickness 8 mm, as they determine fit, bearing area and stiffness.

Can this washer improve joint stability in vibrating applications?
The large outer diameter and solid 8 mm thickness increase bearing area and clamp rigidity, which helps maintain preload under dynamic conditions.
