The 862-403 Bolt, Tap is a specialized fastener used on compatible PowrLiner line stripers. It serves a dual purpose: as a standard bolt for securing components, and as a tap for cleaning or creating threads in existing holes. This design is particularly useful in applications where threads may become clogged with paint or debris, or where components require frequent removal and reinstallation.
Over time, bolts can become stripped, corroded, or damaged due to repeated use, vibration, or chemical exposure. A damaged bolt may fail to achieve proper clamping force, leading to loose components, misalignment, or safety hazards. Replacing with the correct OEM bolt, tap restores secure fastening and ensures that threaded connections remain clean and functional.
