Match the Complete Assembly
DIN 912 is the supplier’s screw reference. Confirm the screw drawing and both washers’ dimensions and material requirements for your selected assembly. A separate assembly standard is not implied.
Full-thread and reduced-shank partial-thread versions are shown separately. The catalogue name for the 160–200 mm reduced-shank items includes a 30 mm note; confirm the actual threaded length against the drawing. Thread coverage is not stated for 304 M8 × 50 (174883) and 316 M6 × 10 (305365).
Markings are reproduced as listed, including THE A2-70, A4-70 and A4-80 options. Unmarked items are shown explicitly. Large-flat-washer, adhesive-patch and fully inspected catalogue families require a separate match.
