SEBO Machine Screw AM5 x 30 (DIN 7985) for SOFTCASE and 370 ELECTRONIC

Thirty millimetres on an M5 thread makes this one of the longer machine screws SEBO lists, specified for the SOFTCASE and the 370 ELECTRONIC. The AM5 designation means a true metric machine thread rather than a screw that cuts its own path into plastic, and DIN 7985 sets the head as a cross-recessed pan head, low and domed, bearing across a wide flat face.

Long machine screws usually indicate a clamped stack, with two or more parts drawn down onto a threaded seat. Put the wrong length in that position and the outcome goes one of two ways: too short and the screw runs out of thread before the stack is tight, so the assembly is held only by friction; too long and it bottoms in the seat and jacks the parts back apart while the driver reports a screw that has gone solid. Part 111 is the size the machine was designed around.

Run it in by hand until finger tight, then take up the last of the load with a driver. A machine thread started crooked picks up a burr along its length that no amount of force will correct, and on a screw this long the crossed thread is well out of sight before the resistance becomes obvious. Replace one whose thread has been damaged rather than persevering with it.

The symptoms that send someone looking for this part are a fastening that no longer holds however far it is turned, a head whose cross recess has been rounded out, or an assembly that has come apart and left one screw unaccounted for. Any of the three ends the same way, with a stack that is no longer clamped and a machine that flexes where it should be solid.
