Titan 858-611 Lock Nut, 1/4"-20

Lock nut 1/4"-20 858-611 for multiple models

The 858-611 lock nut is a 1/4"-20 threaded fastener designed to resist loosening under vibration in compatible sprayer systems. It is specifically compatible with 0528925N_2000_4000; Admiral; Commander; Hydr M nad Hydra Pro Super; Hydra M and Hydra Pro 2000_4000; PowrLiner 4000; PowrLiner 5000; PowrLiner 6000; and PowrTex 15-1 models. This nut incorporates a locking feature, such as a nylon insert (nylock) 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. Lock nuts are commonly used in areas subject to significant vibration, such as motor mounts, pump attachments, and control linkages. They are manufactured to precise specifications to ensure proper fit and reliable locking action. 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. Replacing a worn or missing lock nut with this genuine part restores secure, vibration-resistant fastening. This simple component plays a crucial role in maintaining the integrity of the sprayer's assembly. Using the correct lock nut ensures that critical connections remain tight and reliable throughout operation.
