Threaded Round Spacers M3/M4/M5/M6/M8



The BULK-MAN 3D Threaded Round Spacers are a fantastic solution for creating sturdy standoffs/spacing’s for your projects.

Because the spacer has an M3/M4/M5/M6/M8 ID this keeps the screw snug and centered. These spacers can be used in all sorts of builds such as 3D printers, CNC machines, Robotics, Measuring equipment and instrumentation as well as Other Machinery.

We use the spacers to create a space between the stepper motor and the motor mounting plate. This allows for room to mount hardware such as couplers and belt pulleys to the motor shaft.

They are made from high-quality Aluminium to provide you with a long-lasting product.
