About This Product
This well nut lock nut is a vital hardware piece for mounting various components on a Harley-Davidson, including oil tanks and windshields. It features a 3/8-24 UNF thread and an 11/16" length, providing a secure fastening solution that helps isolate parts from engine vibration. This Zodiac part is designed to function as a replacement for OEM 7780, maintaining the integrity of the original mounting system. Using the correct well nut hardware is essential for preventing stress cracks in bodywork and ensuring that heavy components remain firmly attached. It is a practical choice for routine maintenance or complete custom builds where reliable hardware is a priority.
