| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | OEM Titan 1/4"-20 lock nut designed to resist loosening under vibration across a wide range of Titan spray systems, including Admiral, Commander, PowrTex, PowrCoat, PowrLiner, and Hydra-M models . |
| Function | Incorporates a locking feature, such as a nylon insert or deformed threads, which creates friction against the bolt threads to prevent the nut from backing off due to vibration and dynamic loads . This ensures that critical connections remain tight and secure during operation. The 1/4"-20 thread size is commonly used in areas subject to significant vibration, such as motor mounts, pump attachments, and control linkages . |
| Industrial Applications | Professional sprayer repair, motor mounting, pump attachment, control linkage maintenance, and preventive maintenance across Admiral, Commander, PowrTex, PowrCoat, PowrLiner, and Hydra-M systems . |
| Compatible Systems | Admiral 850-555/850-557; Commander 742-555/742-557; PowrTex 15-1; PowrCoat 730, 745, 940, 960, 975; PowrLiner 4000, 5000, 6000; Hydra-M 2000/4000; Hydra Pro Super; SuperCoat series . |
| Accurate Part Number | 858-611 Lock Nut, 1/4"-20 . |
| Related Parts Commonly Serviced Together | Locking bolts (858-660), trip retainers (742-905), O-rings (742-001), and mating bolts and screws . |
| Common Problems Solved | Fasteners loosening due to vibration, noisy components, misalignment, component failure from loose connections, and loss of locking ability from wear or overtightening . |
| Use with Spray Systems | Supports Titan Admiral, Commander, PowrTex, PowrCoat, PowrLiner, and Hydra-M systems used in industrial finishing, wood coating, metal finishing, line striping, protective coating, and drywall texture applications . |
| OEM & Brand Information | Genuine Titan OEM component designed for correct fitment in Titan spray systems . Over time, lock nuts can lose their locking ability due to wear, overtightening, or contamination . A worn or missing lock nut may allow fasteners to loosen, leading to noise, misalignment, or component failure . Symptoms of a faulty lock nut include the nut spinning easily on the bolt without resistance, visible thread damage, or loose components . |
| Commercial Benefits | Restores secure, vibration-resistant fastening, prevents component loosening and misalignment, reduces noise, ensures reliable equipment operation, and extends equipment service life. |
