Where to buy odd size screws?

Hi everyone,
   I am trying to source some 4-40 machine screws that are greater than 1" long. They can be 1-1/4 or 1-1/2 doesn't matter. Home Depot and Rona only carry them in length up to 1". I am building a robot chassis and the thickness of the motors and the acrylic combined is 1" leaving me no room to thread a nut on the end. Any ideas?



  • wells industrial can usually get some intresting screw sizes..... they are in the same parking lot as SMI at the end closest to canadian tire
  • Good call Rob on going to the hobby shop for the 4-40 threaded rod. They have 12" lengths of several small size threaded rods.
