// Hex nut
// A hex nut is a type of fastener with a threaded hole and a hexagonal outer shape, used in a wide variety of applications to secure parts together. The hexagonal shape allows for a greater torque to be applied with wrenches or tools, making it one of the most common nut types in hardware.


// Define constants (5/16" - 24 thread size)
wallToWallLength = 0.5 
thickness = 0.266 
diameter = 0.3125
