LAHDEK Exhaust Muffler Bolts — 3 Pack

This three-pack supplies replacement exhaust muffler bolts for STIHL petrol chainsaws including the MS290, MS310 and MS390 models. The bolts suit two-stroke, single-cylinder engines running on petrol or gas. They are new replacement parts identified by custom label SCH3197.

Fitment for Stihl chainsaw repairs

The bolts secure the muffler to the cylinder on the listed saw models, allowing the exhaust system to seal correctly during operation. Installing them restores the connection without requiring fabrication or modification of the existing mounting points.

Direct replacement for worn

The set replaces factory hardware that has corroded, stripped or been lost during servicing. The upgrade is worthwhile when the original fasteners no longer hold torque or when reassembling the saw after a muffler or gasket change.
