AMF Conical Washer DIN 6319G – for M20 Screws, Ø23.2 mm Bore, 120° Cone Angle

AMF Conical Washer DIN 6319G provides a standardised seating solution for countersunk fasteners, designed for secure and repeatable mounting in industrial assemblies.

• DIN 6319G conformity
• Precision bore Ø23.2 mm
• 120° cone angle for flush seating
• For M20 screw assemblies

Secure seating for flush countersunk connections

A conical washer manufactured to DIN 6319G gives a defined bearing surface for countersunk screw heads. The standardised geometry reduces variability in joint behaviour and helps prevent eccentric loading of the fastener. Specifying a standardised seating element like this AMF component improves process reliability on assembly lines and in maintenance tasks, as the conical profile guides the screw head into a stable, repeatable position for predictable clamping results.

Precision dimensions that reduce assembly variance

The washer’s measured bore (Ø23.2 mm) and overall geometry, including an outer seating diameter of 50 mm and a height of 8 mm, ensure components align consistently during installation. These precise dimensions lower the need for post-assembly correction and cut down on rework time. When tolerance stacks are critical, using a standardised seating washer limits the number of variables affecting joint integrity and helps maintain torque and preload consistency across multiple fastenings.

Integration into workshop and production workflows

Designed for use with M20 fastenings and featuring a 120° cone angle, this seating washer fits seamlessly into common bolted-joint designs where flush appearance and load distribution are required. Its conformity to a recognised DIN standard simplifies parts lists and procurement, and it is suited to both one-off repairs and serial production. Specifiers and workshop planners benefit from predictable behaviour in load transfer and can include the component directly in assembly drawings and bills of materials.
