Spherical washer DIN 6319C for M12 — AMF, bore Ø13 mm

The Spherical washer DIN 6319C is a precision seating washer designed to compensate angular misalignment and ensure uniform load transfer beneath M12 fastenings in mechanical and structural assemblies

• DIN 6319C standardised seating washer
• For M12 fastenings with Ø13 mm bore
• Compact height H2 4.6 mm for tight spaces
• Spherical seating radius R 17 for self-alignment

Secure seating and consistent load transfer

The spherical washer manufactured to DIN 6319C provides a reliable bearing surface that compensates for angular errors between bolt head and component face. By matching the seating geometry to the mating surface, the washer improves load distribution across the joint and reduces peak stresses that can cause loosening or uneven clamping. For assemblies using M12 bolts, the specified Ø13 mm bore ensures correct running clearance while the spherical form promotes repeatable torque behaviour and safer mechanical connections.

Engineered dimensions for predictable assembly performance

Key measures such as D1 Ø13 mm, D3 24 mm, H2 4.6 mm and R 17 mm define the seating profile and overall fit. The bore diameter (D1) is selected to suit standard M12 shank tolerances; the outer diameter (D3) and spherical radius (R) determine contact area and tilting capacity. These dimensions translate directly into practical benefits: precise centring, consistent clamping force and reduced need for rework. Technical teams unfamiliar with seating washers will find that adherence to standard dimensions simplifies parts sourcing and ensures interchangeability across suppliers.

Practical workshop advantages and supply reliability

Delivered in single-unit packaging for controlled assembly usage, this seating disc supports quality-conscious production and maintenance workflows. The design reduces rework time and supports predictable assembly tolerances, which is particularly valuable for repeat production runs or retrofit work. For procurement and stocking, Metav Werkzeuge’s distribution from Emmerich acts as a quality filter for the European market, helping maintain steady supply and technical guidance for fitment and selection.
