A car hub with the central nut hidden behind a castellated nut cover that is locked against rotation using a cotter pin. Theyre not recommended for use on parts exposed to high vibration because the pin is prone to shearing under prolonged stress.
Equalizer Bolt With Cotter Pin And Castle Nut 7 8 Diameter
Cotter pin castle nut. I just wanted to show you how this would work. One leg of the pin is bent back against the flat of the nut the other is bent up around the end of the axle and pressed tight against the axle end. A few specs on this the length on the bolt from the underneath of the head to the end is 4 1116. A split pin has two long tines that are bent to hold it in place. The longer end of the cotter pin is up so its easy to grab. It includes the castle nut and the cotter pin to lock it into place.
Not true with the prevailing torque or nylock nuts. Low strength steel locknuts for use with cotter pins also known as castle nuts secure these nuts by inserting a cotter pin or safety wire through the slots and a drilled hole in your bolt for mild loosening resistance. The effect is similar to using a castellated nut. Hairpin clips also called r clips are designed to slip on with no bending required. Maybe they will be ok but why take a chance. Insert the pin in the hole until the head bottoms.
A castellated nut sometimes referred to as a castle nut is a nut with slots notches cut into one end. With a finger or tool bend the long end up and over the end of the bolt or shaft tap it down tight. Use cotter pins to lock a castle nut or secure a clevis pin. The diameter is 78 of an inch. Castle nuts are nuts that look like crowns or parapets of mid evil castles. I too was schooled to move the nut to the closest location for the hole in the rod bolt.
These nuts are used together with a bolt and a cotter pin to create a secure nut in place so that it cannot be tightened or loosened. The head is positioned with the long dimension aligned with the shaft or bolt so it fits completely in the slot of the castle nut. A cotter pin is easy to install and remove and is commonly used to secure a wheel or machine component on an axle. If you use a castle nut and wire or cotter pin the nut will never come off. In this example note the head of the cotter pin is set parallel to the length of the axle and is actually set down into one of the notches of the castle nut.
