Description
When you’re dealing with fine thread bolts on your tractor’s hydraulic fittings, PTO assemblies, or implement attachments, you need a nut that won’t back off when things get tough. This slotted hex nut gives you the holding power of a standard hex nut with the added security of a cotter pin slot—perfect for those critical connections where loosening just isn’t an option.
What You’re Getting
- 1-1/8 inch fine thread (UNF) for precise fit on fine thread bolts
- Grade 2 steel construction that’s strong enough for most farm applications
- Zinc plating resists rust and corrosion from weather and chemicals
- Hex design lets you tighten with standard wrenches or sockets
- Slotted head accepts cotter pins for positive safety retention
Built for Real Farm Work
This nut handles the demanding applications you’ll find on tractors and farm equipment—hydraulic connections, PTO assemblies, wheel hubs, and implement attachments. The fine thread pitch provides better clamping force and is commonly used on precision applications where vibration resistance matters. It’s perfect for tractors used in crop farming, livestock operations, hay production, and general farm maintenance.
Made to Last
The zinc plating isn’t just for looks—it gives you reliable corrosion protection against moisture, road salt, and the chemicals your equipment encounters daily. Grade 2 steel provides the right balance of strength and workability for most farm applications without being overly brittle.
Installation Notes
Thread this nut on like any hex nut, then insert a cotter pin through the slots once you’ve reached proper torque. The slots are sized for standard cotter pins. If you’re replacing an old nut, check the bolt threads for damage first—fine threads can be picky about thread condition.
