Stainless Steel Dome Nuts are used to conceal some fasteners and sharp threads for protection. The dome nuts have a dome shaped end that is blunt and does not have sharp lines. Suraj Metal Corporation is a leading manufacturer and supplier of the Stainless Steel Dome Head Nuts in different types, dimensions and lengths. The Stainless Dome Nut is the most used in the industry that has different head types.
The hex head is the most common of the dome nuts. There are different sizes such as the M6 Dome Nut and others. The dome nuts can also be used as lock nuts as they have extra grip. To achieve this purpose, some nuts are Nyloc Dome Nut which has nylon embedded in the internal threads. The threads are tightened with the nylon while installation and the expanded nylon holds the Stainless Steel Cap Nuts in place. These could be seen in automobile wheels, motor wheels and other high vibration applications where the dome nuts do not cause extra friction in the air or liquid and holds tight as a lock not. These are also known as the Acron Nuts in popular terminology in the industry. Please feel free to contact us for more information and pricing of the different types of the dome nuts such as the Flange Cap Nut and others.
