The 570-010 Plated Cotter Key is a small but essential retaining fastener used throughout a wide range of spray equipment, including PowrTwin, PowrLiner, Hydra, HVLP, Epic, Commander, Admiral, and Airless sprayer models. This cotter key is designed to secure pivot pins, linkage connections, and mechanical assemblies where a positive locking method is required to prevent fasteners from loosening due to vibration or operational movement. The plated finish provides corrosion resistance, helping to maintain the integrity of the fastener even in environments where the equipment may be exposed to moisture, solvents, or cleaning solutions.
Cotter keys are commonly used in sprayer assemblies such as trigger linkages, pump connecting rods, wheel axles, and carriage components. These fasteners are designed for single-use applications, as the bending and spreading action required for installation can weaken the metal. Over time, a cotter key may become damaged during removal, corrode from chemical exposure, or simply be lost during disassembly for maintenance. Using a cotter key that is bent, corroded, or undersized can result in loosening of the retained component, potentially leading to equipment malfunction or unsafe operating conditions. Replacing the cotter key with the correct size and style ensures that retained components remain securely fastened during operation. This plated cotter key is manufactured to original equipment specifications for proper fit and reliable retention on compatible models.
| Positive retention | Secures pivot pins and fasteners against vibration-induced loosening |
|---|---|
| Mechanical safety | Prevents critical components from disconnecting during operation |
| Corrosion resistance | Plated finish helps resist rust and chemical degradation |
| After removal | Cotter keys are single-use fasteners and should always be replaced after removal |
|---|---|
| Corrosion damage | Rust or chemical deterioration weakens the fastener and may cause failure |
| Bent or deformed | Previous installation damage or distortion compromises retention ability |
| Missing key | Lost cotter key leaves the retained component unsecured and unsafe for operation |

When replacing a cotter key, these associated components are often inspected or serviced at the same time.
The pin retained by the cotter key should be inspected for wear, scoring, or bending.
Worn bushings or linkage arms may affect the fit and function of the pinned connection.
Missing or worn washers can affect the alignment and retention of the assembly.
