Genuine Honda OEM 90004-ZL8-000 Engine Flange Bolt for Lawn Mowers & Garden Equipment - Perfect for Honda GX Series Small Engines & Power Tools

I had a hard time finding a specific part number for my Honda GC-160 muffler bolts. I took a chance on this one and it works like a charm! I will warn you, if your muffler was as rusted as mine, the bolts will break off inside the engine block. I tried penetrating oil but that wouldn't work. Both my bolts ended up breaking. I broke an easy-out and flute extractor in each bolt trying to remove the them. I ended up having to buy a Milwaukee 3/16 diamond hole saw from Home Depot to remove the extractors and broken bolts. Then I bought a #9 Drill and 6 mm x 1.0 NC Tap Set to re-tap the hole. For any of you that have broken bolts, do yourself a favor and just drill the bolt and re-tap the hole. It's much easier in the long run. Also, the muffler part number I used is 18310-ZL8-010 for my Honda GC-160 engine. Good luck!
