SEBO Torx T20 Screw STS 4 x 20 for FELIX, DART, 370 COMFORT and AIRBELT E — 10 Pack

Keeping a bag of 01017ER on the bench means the 4 x 20 mm Torx screw is never the thing holding up a FELIX or DART rebuild.

These take the deeper fixing holes in the machines listed below, and being longer they carry more of the clamping load in an assembly. That also makes them the ones most likely to be over-torqued and stretched by an impact driver, or to have their T20 recess rounded by a bit that was already worn when the job started. Ten in a bag is enough to renew every screw in a housing instead of putting back the ones that felt a little soft, which is the difference between a machine that stays tight and one that comes back in a month.

The specification matches the single-piece listing exactly: 4 mm nominal, 20 mm under the head, Torx T20 drive, shown at item 52 on the FELIX diagram and item 21 on the DART diagram. Store them separately from the 4 x 16 mm screws in part 01016ER. The heads are indistinguishable at a glance and the only reliable way to tell them apart afterwards is to measure.

• Fits: SEBO FELIX Premium, FELIX 2 Premium, DART, 370 Comfort, and the AIRBELT E1 Kombi, AIRBELT E2 Turbo and AIRBELT E3 Premium canisters
• Size and drive: 4 x 20 mm, Torx T20
• Quantity: 10 screws, part 01017ER
• Single screw: part 01017
• Diagram positions: FELIX item 52, DART item 21
• Shorter version: 4 x 16 mm, part 01016ER

A quick way to tell the two STS lengths apart without measuring: keep them in their bags until the moment they go back in the machine, and put the loose ones from the strip-down in a separate tray. Once the 16 mm and 20 mm screws are mixed, only a ruler will separate them again.

Every screw in the bag is genuine SEBO hardware, made to the same specification as the ones fitted on the production line.
