Browse aftermarket nuts for skid steer loaders, compact track loaders, and tractors, including hex nuts, hex jam nuts, flange nuts, acorn nuts, nut retainers, and wheel nut kits.
Match your nut by OEM part number for the correct thread and seat. Details are listed on each product page.
A nut is defined by more than its thread. The style determines how it locks, how it spreads load, and what it seats against, and those three things are what make one nut correct where another of the same thread is not. Common replacements include the acorn nut replacing OEM 7251278, the hex jam nut replacing OEM 7D4, the hex nut replacing OEM 4DM10, the wheel nut replacing OEM 6564669, the nut retainer replacing OEM 6706104, the flange nut replacing Kubota 02756-50060, and the wheel nut kit replacing John Deere N172058.
Wheel nuts deserve the most care on this page. They are torque-critical, and many use a shaped seat, conical or spherical, that has to match the seat machined into the rim. A wheel nut with the wrong seat contacts on an edge instead of a face, will not hold torque, and works loose no matter how carefully it was tightened.
Hex nuts are the general-purpose fastener and are usually paired with a washer or a locking method. Jam nuts are thinner and are designed to lock against a second nut or a housing, which is why they appear on adjustable linkages and tie rods rather than on plain joints. Fitting a jam nut where a full-height nut belongs leaves fewer threads engaged than the joint was designed for.
Flange nuts carry an integral washer face that spreads clamp load and resists loosening, and they suit sheet metal and castings where a plain nut would dig in. Acorn nuts cap the thread, keeping dirt and moisture off a stud that would otherwise seize. Nut retainers hold a nut captive where there is no way to get a wrench behind the joint.
Any nut with a nylon insert or a deformed locking thread is a single-use item. It locked the first time by being deformed on the way on, and it will not do that again.
