Frequently Asked Questions (FAQs)

1. What size nut goes on a spindle?

The standard size nut that goes on a spindle is 3/4 In. -16 with a hex size of 1-1/16 In.

2. What does a spindle adjusting nut do?

A spindle adjusting nut is used to precisely position spindles. It remains in position while the spindle rotates, and the desired position is fixed by two opposing round nuts.

3. How do I know what size nut I need?

To determine the size of the nut needed, you can use a tape measure. Place the nut on a flat surface, keep the hole clean and open, and measure the nut starting from one end up to the outer perimeter. If the nut follows a US standard, you may need to divide the tape measure into sixteenths.

4. What is the most common spindle nut system?

The most commonly used spindle nut system is the double jam nut system.

5. Why can't you reuse a spindle nut?

You should not reuse a spindle nut because a previously used nut will not sustain the necessary torque when reused. It is important to get a new nut for reinstallation to ensure proper functionality.

6. Can you reuse a spindle lock nut?

Similar to a spindle nut, a spindle lock nut should not be reused. It is recommended to get a new lock nut for reinstallation to ensure the necessary torque is sustained and proper functioning is maintained.
