4-40 Thumb Nuts with Set Screw for Vintage RC Vehicles (JCO5238-1)

The 4-40 thumb nuts with set screw are a must-have for securing battery packs in vintage RC vehicles, such as the RC10 and RC10T. These components provide a quick and efficient way to install and remove batteries, replacing the traditional method of using screws and washers. Each package contains two aluminum, knurled thumb nuts designed to securely press down into battery braces, ensuring your battery stays in place even during dynamic movement.

Accompanying these thumb nuts are 5/8” long set screws, making installation straightforward by allowing for secure attachment to battery cups or buckets. This innovative design simplifies battery management, making it easier than ever to adapt vintage vehicles for modern LiPo battery usage.
