The 862-402 Acorn Nut is a domed cap nut designed to cover exposed bolt threads on compatible PowrLiner, PowrTex, and PowrTwin line stripers and plural component sprayers. Its rounded, closed-end design provides a finished appearance while protecting threads from corrosion, damage, and debris. It also helps prevent injury from sharp protruding threads and snagging on clothing or materials.
Over time, acorn nuts can become corroded, damaged, or lost due to vibration, chemical exposure, or impact. A missing or damaged nut leaves threads exposed, increasing the risk of injury, corrosion, and thread damage that can make future disassembly difficult. Replacing the acorn nut restores a clean appearance, ensures thread protection, and maintains safety standards.
