LiftMaster K45-50676 Cludge Cover Thumb Screw for Select Swing Gate Operators
The LiftMaster K45-50676 is a replacement thumb screw used to secure the cludge cover or related cover hardware on compatible swing gate operators. It is commonly described as a cludge thumb screw, star knob screw, or star knob bolt. The star-style head allows the cover fastener to be tightened and removed more easily during service without treating it like a generic machine screw.
On compatible operators, this screw helps keep the cover properly seated. That matters because loose or missing cover hardware can let panels vibrate, expose internal components, or allow water and debris to enter areas that should remain protected. A missing thumb screw may seem minor, but it is worth replacing with the correct part instead of forcing a hardware-store substitute.
The strongest compatibility references tie K45-50676 to select LiftMaster/Elite swing gate operator models, including CSW, RSW, and Robo series references where the parts breakdown calls for this screw. Because cover designs vary by model and production year, the original hardware and cover style should be checked before ordering.
