What is the difference between a castle nut and a slotted nut?

A castle nut, also known as a castellated nut, is a type of nut that has a series of slots cut into one end. These slots are designed to accommodate a cotter pin or split pin, which is used to secure the nut in place. Castle nuts are commonly used in situations where it is important to ensure that the nut cannot loosen, such as in automotive or aerospace applications.

On the other hand, a slotted nut, also known as a castle-less nut, is a type of nut that has a single slot cut into one end. This slot is not designed to accommodate a cotter pin or split pin, but rather to allow for a tool, such as a screwdriver or spanner, to be inserted to tighten or loosen the nut. Slotted nuts are commonly used in situations where the nut needs to be tightened or loosened frequently, such as in machinery or equipment.

How do you measure a slotted screw?

To measure a slotted screw, you can use a ruler or a caliper. Here are the steps to follow: Determine the screw's nominal size: This is usually indicated in the product description or packaging. If you don't have this information, you can measure the screw's diameter at the widest part of the threaded portion. Measure the length of the screw: Use a ruler or caliper to measure the length of the screw from the tip to the base of the head. Measure the width of the slot: Use a ruler or caliper to measure the width of the slot at its widest point. Determine the screw's thread pitch: This is the distance between the threads on the screw. You can use a thread gauge or measure the distance between the threads using a ruler or caliper. By measuring these four parameters, you can identify the correct replacement screw or find a suitable screw for your project.
