4-Pack 502310 LH Threaded Blade Bolts - Compatible With King Kutter & FM5/FM6 Lawn Mowers

About This Product

Lawn mower owners, if you're replacing blades on your King Kutter or similar mower, you'll need these specific left-hand thread bolts. This set includes four 502310 LH threaded blade bolts that fit a bunch of popular models like King Kutter Finish 555009, 502303, 502300, 502301, 155009, 156026, 5022310, 21-023, 167133, 502313, and FM5/FM6 mowers. They're made from hot-forged steel, so they're tough, hardened, and can handle the high-speed stress of a spinning blade. The left-hand thread is key – it tightens in the opposite direction of the blade's rotation, which helps prevent the bolts from loosening during use. The hex head fits a standard wrench, making installation and removal straightforward (no special tools needed). Just make sure you're turning the correct way – remember, lefty tighty, righty loosey here! These bolts are essential for securing your mower blade safely to the deck. Using the wrong bolt or a worn one can be dangerous, so it's worth getting the right part. They're corrosion-resistant enough for outdoor use, even in damp or grassy conditions. Whether you're doing routine maintenance, replacing a damaged blade, or just keeping spares on hand, this 4-pack gives you enough for multiple blades or future changes. Always double-check your mower model before ordering to ensure compatibility. Keep your mower running smoothly and safely with these reliable replacement bolts.
