Description
When you’re working on heavy machinery or need a nut that can handle serious stress, this slotted hex nut is the one to reach for. The slots allow for cotter pin installation, giving you that extra security when safety’s critical—whether you’re securing wheel components, linkage points, or other high-stress connections where a loose nut just isn’t an option.
What You’re Getting
- 1-1/4 inch diameter with UNF fine threads for secure engagement in high-stress applications
- Zinc coating protects against corrosion from weather, chemicals, and road salt
- Slotted castle design accepts cotter pins for positive retention and safety
- Grade 2 steel construction provides reliable strength for agricultural and industrial use
- Precision threading ensures smooth installation and proper torque retention
Built for Real Farm Work
This heavy-duty nut is designed for agricultural equipment, construction machinery, and industrial applications where vibration, stress cycles, and harsh environments demand reliable fastening. The large 1-1/4 inch size handles substantial loads, making it ideal for wheel assemblies, hydraulic connections, and structural mounting points on tractors and implements.
Made to Last
The zinc plating isn’t just for looks—it forms a protective barrier that resists rust and corrosion even in wet conditions. Grade 2 steel provides the right balance of strength and workability, while the fine UNF threads give you more engagement per inch for applications where holding power matters most.
Installation Notes
Always use the correct cotter pin size for the slots and ensure proper installation through both slots for maximum security. Apply proper torque specifications for your application, and remember that fine threads require less torque than coarse threads to achieve the same clamping force. Keep a few extras on hand—when one component needs replacement, others might not be far behind.
