What are Bolts with Hole for Cotter Pin?
Bolts with holes for cotter pins, also known as castle nuts, are fasteners that have a drilled hole at the end of their shank. This allows for a cotter pin to be inserted through the hole to secure the bolt in place.

Considerations Before Buying Bolts with Hole for Cotter Pin
- Type: There are different types of bolts with holes for cotter pins, such as hex head, carriage, and flange bolts. Consider which type is most suitable for your specific application.
- Size: The size of the bolt should match the size of the hole it will be inserted into. It is important to measure both the diameter and length of the bolt to ensure a proper fit.
- Material: Bolts with holes for cotter pins can be made from various materials such as stainless steel, zinc-plated steel, or galvanized steel. The material chosen should depend on factors such as strength requirements and resistance to corrosion.
- Cotter Pin Size: It is important to make sure that the cotter pin you use is compatible with the size of the hole in the bolt. The standard sizes for cotter pins are 1/16 inch increments from 1/16 inch to 5/8 inch.
Tips for Choosing High-Quality Bolts with Hole for Cotter Pin
