Description
Overview:
This Muffler/Exhaust Screw M5 x 65 mm is a Genuine Stihl OEM fastener designed to secure the silencer (muffler) assembly on selected Stihl chainsaws, including the MS230 and MS230C. Built from high-strength steel with a durable finish, it copes with heat and vibration around the exhaust, helping to keep the muffler tight and the saw performing as it should. The precise M5 thread and 65 mm length ensure correct engagement in the mounting boss for reliable clamping. Its Torx drive head provides solid tool grip for controlled tightening and reduced cam-out. Ideal for routine maintenance or repair, this screw is a direct-fit replacement that restores secure fastening of the exhaust components on compatible models.
