Loose bolts, missing screws, and corroded fasteners are silent killers of mower performance. When blades vibrate, belts slip, or the deck rattles, you're usually looking at fastener failure. Genuine OEM Murray fasteners—bolts, nuts, washers, and clips—are engineered to the exact specifications your mower needs to stay solid and safe through the season. They resist vibration loosening and corrosion far better than generic hardware store alternatives.
If your Murray isn't cutting evenly, the deck is shifting, or parts are rattling loose, fasteners are often the culprit. Browse our full selection of Murray lawn mower parts and find the exact fastener kit or individual hardware your model requires. Locate your model number on the mower frame or under the seat—it's usually a 12-16 character code—and we'll match you quickly.
Lawn mower engines vibrate constantly, and generic fasteners lack the precision fit and material grade of OEM hardware. Murray fasteners are spec'd to resist vibration lockout and engineered with the right pitch and thread tolerance. Replace corroded or mismatched fasteners with genuine OEM parts, and use a torque wrench if your manual specifies torque values—over-tightening and under-tightening both cause failure.
Locate your model number on a metal or plastic plate usually mounted on the frame near the engine, under the seat, or on the back of the mower. It's typically a 12-16 character alphanumeric code. Enter it into Repair Clinic's search bar, and we'll display every fastener part available for your exact model, from individual bolts to complete hardware kits.
If one fastener is corroded or loose, inspect the rest immediately—vibration issues affect the whole mower. Replacing a full fastener kit during seasonal maintenance prevents mid-mowing breakdowns and ensures your deck stays perfectly aligned. OEM kits are cost-effective insurance against poor cutting and safety hazards.
OEM Murray fasteners match your mower's exact thread pitch, material grade, and length. Generic hardware often misfit, strip easily, and corrode faster. Using genuine parts support proper fit and performance and help ensure compatibility—critical when deck balance and blade safety are on the line.

Murray typically places the model number on a label attached to the mower deck or frame, though some models list it on the engine housing or under the seat.

Type it into our model number lookup and the catalog narrows to parts made for your unit, across every part category. That means fewer wrong orders and a faster repair.
