Product details
A bag of ten short 3.9 x 9.5 mm screws, part 01027ER, for the shallow fixings in SEBO power heads and the machines that carry them.
Shallow-seated fasteners are the ones that shake free first, since there is less thread holding them and they sit in a high-vibration part of the machine. Finding one rattling loose in the base usually means a second has already gone missing unnoticed. Ten spares let the whole set be renewed in one pass instead of chasing them one at a time over successive services, and it saves the bench time compared with hunting for a screw mid-rebuild.
The specification is DIN 7981 with a flat F point, 3.9 mm across and 9.5 mm long, appearing at item 121 on the ET-1/ET-2 and DART diagrams and item 152 on the FELIX diagram. Keep them separate from the longer shell screws, because the difference between 9.5 mm and 13 mm is not obvious in a parts tray and only one of the two belongs in a shallow boss. The 13 mm version is 01021ER and the 21 mm one is 01020ER, which together cover every screw length in a standard power head strip-down.

- Other lengths for the same shell: 01021ER and 01020ER
A small habit worth adopting on a power head rebuild: replace every short fixing from the bag rather than mixing new screws with the ones that came out. A single tired fastener in a shell held by several is enough to let a corner lift, and the whole point of the bag is that there is no reason to let it happen.
