The CapSpray 0275574 Set Screw is a precision fastener used to lock adjustment controls, needle guides, or other rotating parts in place on the Maxum II turbine HVLP system. A properly seated set screw ensures that settings remain stable during operation, preventing drift that can affect material flow, pattern shape, or fan width.
Over time, set screws can become stripped, lost, or loosen due to vibration. A missing or damaged screw can lead to inconsistent spray performance, unintended adjustment movement, or even component separation. Replacing with the correct OEM screw restores secure fastening and reliable operation.

When replacing a set screw, consider inspecting or replacing these associated components to ensure a complete repair.
If the screw was lost or stripped, the mating knob may have worn threads or a damaged hub.
On models where the set screw secures the needle guide, inspect the needle for straightness and wear.
Check for cracks or deformation around the set screw mounting point if overtightening occurred.
