SEBO Machine Screw AM4 x 12 (DIN 84) - 10 Pack

DIN 84 is the standard that fixes the shape of this fastener: a slotted cheese head, meaning a straight blade slot across a cylindrical head that sits proud of the surface rather than sinking into it. Add SEBO's AM4 x 12 designation and you have a metric M4 machine thread, 12 mm long under the head. Part 0117ER supplies ten of them in one bag, which is how a service job avoids stalling over a single missing screw.

The distinction that matters is machine thread against self-tapping. A tapping screw cuts its own path into plastic and wears that path a little each time it comes out. A machine screw such as this one runs into a thread that already exists, in a metal insert or against a nut, so it can be removed and refitted through repair after repair without losing its grip. That is why SEBO puts it at the points a technician opens routinely.

A screw whose thread has worn will keep turning without ever going tight, and the panel it was meant to clamp buzzes against the housing in use. Once the slot itself has been chewed by a blade that was too narrow, the next removal is worse than the last. Ten fresh screws in the drawer settles both problems in seconds.

Anyone searching for a SEBO AM4 x 12 screw, a DIN 84 machine screw for a vacuum, or an M4 x 12 SEBO replacement fastener is looking for this pack. Compare the head form and the thread of the screw you took out against the specification above before ordering, since SEBO also lists M4 x 12 screws to DIN 966 under part 129 and to ISO 7380 under 0199ER, and the three differ only in the shape of the head.
