Flange Nuts

China hex flange nut, which have a wide flange at one end, act as an integral gasket, which distributes the pressure of the nut across the part being secured, reducing the possibility of component damage. The china hexagon flange nut can be serrated to provide locking. The serrations help prevent the vibration of the nut from moving the fastener, enhancing retention.

China flange lock nut are mostly used in pipe connections or workpieces that need to increase the contact surface of the nut.

All items are produced in strict accordance with industry standards or client-specific requirements.
