A hex head cap screw is a fully threaded or partially threaded fastener used to clamp and secure structural and mechanical assemblies on the machine. The correct grade rating ensures the fastener can handle the clamping loads placed on it without stretching or shearing under stress. Using an undersized or incorrect-grade fastener in these applications risks joint failure, which on an aerial lift can compromise the integrity of the assembly it secures — making it essential to replace worn or damaged screws with the correct OEM part every time.
