Types of Self Locking Nuts and Bolts

Fastenwell manufacture and export below type of nuts:

Hex nuts, which are hexagonally shaped. We produce and supply finished hex nuts, hex flange nuts, heavy hex nuts, and slotted hex nuts.
Flange nuts, similarly to flange bolts, flange nuts feature a round flange that acts as an external washer.
Coupling nuts, are a longer, cylindrical nut that joins two male threads.
Lock nuts, are available in a range of shapes and are used to secure other nuts and prevent them from loosening.

Types of lock nuts include all metal lock nuts, top or side locking nuts, serrated hex flange nuts, and lylon lcok nuts.
Slotted nuts are designed and constructed such that they can form a locking mechanism with a cotter pin or a safety wire.
Square nuts are characterized by their square shape. This head shape increases the surface area of the fastener and the amount of

friction it experiences, reducing the risk of it loosening.
