The recommended supplies for the worm are hardened metal and bronze for the worm equipment.

In addition to metal and hardened metal, worms are accessible in stainless steel, aluminum, bronze, and nylon worm gears are accessible in steel, hardened metal, stainless metal, aluminum, nylon, and non-metallic (phenolic).
