Need to secure the blade on your Husqvarna trimmer/brushcutter? This is a replacement blade nut with a LEFT-HAND thread (it tightens clockwise, loosens counter-clockwise, which is opposite of normal). It fits a long list of Husqvarna models including the 36R, 39R, 165R, 165RX, 240R, 245R, 244R, 250R, 252RX, and 265RX. The part numbers it replaces are 502 04 55-01 and 258 11 71-12. It's unbranded but new. Using the correct left-hand thread nut is crucial for safety—it keeps the blade from loosening during operation. If your old nut is stripped, lost, or you're installing a new blade, this is the part you need. A simple, inexpensive piece of hardware that's vital for safe and proper brushcutter function.
