2X OLEO-MAC GSH400 Chainsaw Guide Bar Nut

Guide bar nut set (2x) fits Oleo-Mac GSH400 and many other chainsaws. These nuts secure the guide bar onto the bar studs, clamping it firmly against the sprocket cover so the bar stays correctly tensioned and aligned during cutting. When a nut becomes stripped, corroded, or its thread wears out, the guide bar can no longer be tightened securely, leading to a loose bar, difficulty holding correct chain tension, or the bar shifting during use. Fitting new nuts restores a secure, properly tightened guide bar mount.
