SEBO B 4.3 Washer (DIN 9021) for SOFTCASE CE12 — 10 Pack

SOFTCASE CE12 owners need a different 4.3 washer from the one the upright range uses, and the difference is not the hole. Part 0150ER is the B 4.3 washer to DIN 9021, supplied ten to a pack, and SEBO places it at position 168 on the SOFTCASE CE12 parts drawing.

The bore takes M4 hardware, but DIN 9021 is the large-outside-diameter pattern: for a given bore it presents a noticeably wider face than the DIN 125 washer stocked under 0140, which is precisely why SEBO calls it up here. Fitted under a screw head it spreads the clamping load across more of the panel, so the head cannot pull through a thin moulding or score a ring into the surface beneath it. The two standards share a hole size and are not substitutes. Reaching for a DIN 125 washer here leaves a smaller footprint under the same head, which is the opposite of what the joint was designed around.

Order these when a CE12 panel screw has begun to sink, when the plastic around a fixing has gone dished or crazed, or when the washers have simply not survived a previous service. Ten covers a full canister strip-down with a few left over. It is also the sensible quantity for anyone who services CE12 machines regularly, since these washers tend to be the parts that go missing between the bench and the parts tray rather than the parts that fail outright.
