The 759-067 Slotted Hex Nut is a genuine OEM fastener designed for PowrLiner 2850, 1800M, and 2800M airless sprayers. This specialized hex nut features precision-machined slots that allow for the installation of a cotter pin or safety wire, providing a positive mechanical lock that prevents the nut from loosening even under severe vibration or dynamic loading.
Slotted hex nuts are typically used in critical applications where fastener loosening could result in equipment damage, fluid leaks, or safety hazards. The slots align with holes in the mating bolt or shaft, allowing a cotter pin to be inserted through the nut and bolt, physically preventing rotation. This positive locking method is superior to friction-based locking devices in applications with extreme vibration or where maintenance access is limited.
This genuine nut is manufactured to exact factory specifications for thread size, pitch, material grade, and slot dimensions. Using the correct slotted nut ensures proper engagement with the cotter pin, correct torque capacity, and reliable long-term retention of critical components such as pump linkages, drive mechanisms, and wheel assemblies.
| Component retention | Secures critical components such as linkages and drive mechanisms |
|---|---|
| Safety locking | Accepts cotter pin for positive mechanical lock against rotation |
| Vibration resistance | Prevents loosening in high-vibration applications |
| Load distribution | Distributes clamping load evenly across threaded connection |
| Stripped threads | Nut will not engage or tighten properly on bolt |
|---|---|
| Damaged slots | Slots are deformed, preventing cotter pin installation |
| Corrosion / rust | Visible corrosion affecting nut integrity |
| Missing nut | Nut lost during disassembly or operation |

When replacing a slotted hex nut, it's good practice to inspect these related components.
Always use a new cotter pin when installing a slotted nut. Never reuse cotter pins.
Inspect mating bolt or stud threads for damage, stretch, or wear. Replace if necessary.
Check washers for deformation or crushing. Replace to maintain proper clamping.
