Whether you are building an elite custom drivetrain or a championship manipulator, you need your components to stay where you want them. They can also be used on round shafts and bolts (5mm is great for #10 hardware!). If you need to space a lot, grab some 1 in. spacers. If you need ultimate precision, pick up some 0.063 in. spacers. Not sure which spacers you need? Keep a handful of all six sizes in your shop and never go hungry for spacers again!

These spacers are made of black polycarbonate, a tough, crack resistant material that FIRST teams are familiar with. These spacers should resist stress cracking. However, if polycarbonate isn't rugged enough for your high load application or you need custom length spacers, check out our Aluminum Hex Spacer Extrusion.
