About This Product
This pack of 25 zinc-plated 3/8-16 locknuts from Gardner-Westcott is a versatile addition to your fastener drawer. These nuts serve several critical roles across different Harley-Davidson families. On 1949 to 1982 FL and FLH models, they are used as the 3/8 hex locknut for mounting turn signals to the spotlamp. For newer machines, they act as the primary chain tensioner plate mount nut on 2001 to 2006 Big Twins, excluding 2006 Dyna models. They also fit 1997 to 2004 XL Sportsters for chain tensioner applications. Replacing OEM 7778, these fasteners provide a secure, vibration-resistant hold that is necessary for both chassis and internal engine components.
Manufacturer part number: 03550-25 PACK.
