The 759-515 Acorn Nut is a domed cap nut with 1/2-13 thread size, designed to provide a finished appearance and protect exposed bolt threads on compatible PowrLiner 2850, 1800M, and 2800M sprayer models. Its rounded, closed-end design covers the end of the bolt, creating a clean look while shielding threads from damage and corrosion.
Acorn nuts, also known as cap nuts or dome nuts, serve both functional and aesthetic purposes. Functionally, they protect exposed bolt threads from impact damage, corrosion, and contamination. Aesthetically, they provide a finished, professional appearance by covering the sharp edges and ends of bolts. The 1/2-13 thread size indicates a nominal diameter of 1/2 inch with 13 threads per inch, a common coarse thread specification for medium-duty fastening applications.
Over time, acorn nuts can become corroded from environmental exposure, damaged from impact, or lost during maintenance. A damaged or missing acorn nut leaves bolt threads exposed, increasing the risk of thread damage and detracting from the equipment's appearance. Replacing worn or missing acorn nuts restores thread protection and maintains a professional look for your sprayer.
