Hex nut, as the name suggests, is a six-sided mating fastener with internal machine threads, for screwing on to the shank of hex bolts or threaded rods to create a reliable joint, even under high movement, heavy loads and high wear. Thus, it is perfect for industrial applications where high resistances against wear, stress and strain are required.

At Shunfeng, hex nuts are made of a variety of materials like steel in grade 4.8, 8.8, 10.9 and 12.9 as well as stainless steel 304 and 316, etc. Steel hex nuts are available in wide range of shapes, sizes and platings including clear, yellow or black zinc for added corrosion resistance. Meanwhile, hex nuts can be customized to meet the tightest tolerance and your exact requirements.


Two clear zinc plated hex nuts in standard type.
Standard hex nuts
Standard hex nuts are the most common and versatile fasteners used in general applications. Upon request, Shunfeng quality hex nuts are available in both right hand and left hand, range from M6 to M24.
Two stainless steel heavy hex nuts in larger size and shiny surface.
Heavy hex nuts
With larger and thicker bodies than standard nuts of the same size, heavy hex nuts exhibit higher strength and better resistance to stretching and widening. And They match well with large diameter and high strength bolts.
Two jam hex nuts are plated with clear zinc
Jam hex nuts
About half the height of a standard nut, jam hex nuts are often used to lock standard hex nuts in place. In addition, jam nuts are usually tightened against the work surface in situations where a standard nut is not fit.
Three stainless steel panel hex nuts in different sizes.
Panel hex nuts
As a much thinner nut than jam hex nuts, this one has a relatively large hole and is generally used in potentiometer control, switch hardware and other areas where a low profile is required.
