SEBO Screw 4 x 10 for the 300 MECHANICAL Upright

Short, stout and specific: the 4 x 10 is listed for one machine, the SEBO 300 MECHANICAL, where a 4 mm screw is called for but only 10 mm of depth is available to take it. Part 1042 is that screw, supplied one at a time so a single-fastener repair stays a single-fastener repair.

Its shortness is the point rather than an economy. Anything longer bottoms out against whatever sits behind the boss, and the resistance felt through the driver reads as tight while the panel is still loose. Worse, a screw that has bottomed and then been forced puts its whole load onto the end of the boss and splits it from the inside, where the damage cannot be seen until the housing comes apart.

• Part number: 1042
• Fits: SEBO 300 MECHANICAL
• Size: 4 mm diameter, 10 mm long
• Application: shallow fixing points where depth behind the boss is limited
• Sold: each

Replace one when the thread has stripped, when the head has rounded under a slipping driver, or when the original disappeared during a strip-down. Start it by hand for the first turn so the thread follows the path already cut into the plastic rather than carving a second one alongside it, then finish with a driver and stop as the head seats.

Ordering by part number takes the guesswork out entirely, which matters here because a 4 mm screw of almost any length will start in this hole and only the correct one will hold in it. A screw that has cut a second path alongside the first never holds properly afterwards, because neither thread has full material behind it. Searches for a SEBO 300 MECHANICAL screw, a SEBO 4 x 10 short fastener or a genuine SEBO 1042 all point to this listing. Confirm from the data plate that the machine is a 300 MECHANICAL before ordering. Genuine SEBO fastener supplied by an authorized dealer, shipping in 2-5 business days.
