What the screw in a coffee machine does

The screw is a fastening element that holds other parts of the coffee machine in place – covers, spouts, seals, holders or structural parts. Without a properly tightened and undamaged screw, joints loosen, parts shift out of position, or play appears between them.

How wear shows up

A damaged or corroded screw shows up as loose parts, creaking or knocking while the coffee machine is operating, uneven seating of covers, or water leaking at the point where the screw was meant to keep a seal under pressure. Worn or deformed threads or a damaged screw head often make it impossible to tighten or remove with standard tools.

Why you shouldn't put off the replacement

A loose or damaged joint can, over time, cause a bigger fault in the part it holds – ranging from leaks to mechanical damage of surrounding parts. Replacing the screw itself is a simple and inexpensive fix that prevents unnecessary follow-on damage.

How to choose the right screw

When choosing, the exact head type, length and thread size are important, as these vary between the different points of use in the coffee machine. Check compatibility and dimensions in the product table so the screw fits exactly in its original position.
