    Also known as chrome-moly steel, these 4130 alloy steel round tubes have low carbon content for good weldability. They’re often used for roll cages and frames. To increase their wear resistance, you can harden them with heat treating.

    With ID tolerances sized specifically for reamers, these bushings ensure steady and precise hole finishing. Press them into a fixture plate with a manual or hydraulic press for permanent installation. Also known as headless bushings, these ANSI-type P bushings don’t need counterboring to be mounted flush. They are made of hardened, ground steel that holds its shape and resists wear, so they last for many cycles without needing to be replaced.

    Also known as jig bushings, these drill bushings fit inside fixture plate holes to precisely guide drill bits, counterbores, reamers, and other cutting tools. They improve accuracy so your drilled holes and cuts are consistent from part to part. Known for their versatility, drill bushings are also used as spacers, shims, and machinery bushings.
    Press into place with a manual or hydraulic press. Since these bushings are sized slightly larger than the hole for an extremely tight fit, they’ll stay put permanently. These are ANSI Type P bushings—also known as headless bushings—which means you don’t need to counterbore the hole to mount them flush.
