Match the Complete Assembly
This two-piece configuration contains a screw and a flat washer. The table separates 58 items named as THE-standard assemblies from one additional knurled catalogue variant. M8 × 20 has two references: 253228 for the THE-standard entry and 304254 for the knurled variant. Confirm which item your drawing requires. Spring-washer-only and flat-plus-spring combinations are separate products. Confirm the flat washer dimensions and material requirements against the selected item’s drawing.
DIN 912 is the supplier’s screw reference. A separate national or international washer-assembly standard is not implied. Markings are reproduced where provided; an unspecified or unmarked entry does not establish a strength class.
