0.375 in. ID 0.500 in. OD Aluminum Spacer at Various Lengths

This spacer is designed to fit on a shaft or screw that is 0.375 in. in diameter. Spacers help keep things in place in a multitude of ways. You can use this to slip over a shaft that is smaller than the inside diameter, between objects where it gets smashed between them with other fasteners, or help center a shaft of smaller size into a larger hole. Not seeing the length you're looking for? Consider stacking several together.
