Our team of highly qualified & experienced workforce helps us in manufacturing and supplying Castle Nuts. These nuts are designed to be used with a threaded bolt having a pre-drilled hole where a cotter pin can be used to secure the fixing. To manufacture these nuts, we use optimum quality alloy steel and carbon steel. These are useful for locking certain items in place when you do not want to use other nuts and bolts. Castle Nuts are characterized by the notches present on one end. Available in different sizes and specifications, these are ideal for applications where vibration may undo the fixing.
