HALF CASTLE NUT STEEL D937 30MM X 1.5

Quantity:

A half castle nut is a variation of the standard castle nut, featuring a lower profile while maintaining the same slotted design. It is used with a drilled bolt or stud and secured by inserting a split pin (cotter pin) through the slots to prevent loosening. The reduced height makes it ideal for applications where space is limited or weight reduction is important.
