SEBO M4 x 12 Screw, ISO 7380 Button Head, for C Series Canisters

Button-head screws sit low and rounded against the surface they clamp, which is the look and the clearance SEBO wanted on the C series. ISO 7380 is that head standard, and part 199 is the screw in M4 x 12, sold one at a time.

• Fits: SEBO C series canisters
• Size: M4 x 12
• Standard: ISO 7380, button head
• Pack: sold individually
• Installation: goes back into the original boss, no drilling or tapping
• Order as: SEBO part 199

The head profile is the part worth paying attention to. A countersunk screw dropped into a hole meant for a button head will pull itself down into the plastic and split it, while a pan head can stand too proud and catch on a hose or a hand. Matching the standard as well as the thread keeps the panel sitting flush the way it left the factory.

Lose one of these and the panel it holds knocks against the body every time the canister is dragged over a threshold. Strip one and it will not pull down at all, leaving a visible gap running along the seam and a housing that flexes under thumb pressure. Both are quick fixes once the right screw is in hand, and both get worse if the machine keeps being used with the fastening missing.

Because a canister spends its life being dragged, lifted and set down again, the fasteners along its seams take shock loads a machine sitting on a bench never sees. It is worth running a driver over the visible screws once a year and renewing any that no longer feel positive, rather than waiting for one to vanish into a carpet.

This listing covers searches for a SEBO C series screw, an M4 x 12 button head canister screw and genuine SEBO 199. Compare the head against the screw you took out before ordering, and count how many positions you are short — ordering a spare at the same time saves a second wait later on.
