SEBO 4.3 Flat Washer (DIN 125) for ESSENTIAL G Series — 10 Pack

Washers rarely go missing one at a time. They come off during a teardown, roll somewhere under the bench and never all come back, so 0140ER supplies the 4.3 bore DIN 125 washer in tens for the SEBO ESSENTIAL G uprights.

Each one goes beneath an M4 screw head to spread the clamping force over a wider footprint of plastic or sheet metal. Once a washer has cupped or picked up corrosion it no longer sits flat, and the fastener above it works loose over the next few hours of run time. Replacing the set while the machine is apart is faster than chasing an intermittent rattle later, and it costs nothing in time when the screws are already out. SEBO marks this washer as position 174 on the ESSENTIAL G4/G5 sheet, alongside the M4 screws it is meant to accompany.

Fit them where the drawing shows them and nowhere else. Adding a washer under a screw that was designed without one changes how deep the fastener sits and can leave it short of thread, while leaving one out where it belongs concentrates the whole clamping load on a narrow ring of plastic. The parts sheet is the arbiter in both directions.
