It is designed for use with Sierra anode kits 18-6011, 18-6014, and 18-6016, giving boat owners a reliable, correctly sized bolt when replacing worn or corroded anode hardware rather than reusing a compromised original fastener.\u003c\/p\u003e\u003cp\u003eBuilt from stainless steel for corrosion resistance in the marine environment, the bolt features a flat head style with a hex head type and UNC threading, sized to match the mounting holes on compatible Mercury outboard anode assemblies. Sierra manufactures the 18-6245 to meet or exceed the quality of the original equipment part it replaces, and it cross-references directly to Mercury Marine and Mercruiser hardware as well as GLM aftermarket numbers, making it easy to identify as a drop-in replacement.\u003c\/p\u003e\u003cp\u003eThis is a small, low-cost item intended for routine anode maintenance and replacement, an essential and recurring task for protecting outboard lower units, engine components, and other submerged metal parts from galvanic corrosion.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
