About Acorn Nuts
Acorn Nuts or Acorn Cap Nuts are special fasteners that are defined by the top being highly domed that fully covers the threaded part of a bolt or screw. The domed shape of these nuts, unlike regular hex nuts, exposes the thread but offers a smooth finished look that does not cause any injury because of sharp edges and shields the bolting joint against external dirt.
These Domed Nuts feature a hexagonal base that allows for easy wrenching and torque application, making them compatible with all types of machine bolts and threaded rods. They are greatly appreciated in the most aesthetic and safety conscious industries in the world like in consumer products, furniture and bare architectural structures.
At Jade Alloys, our acorn nut dimensions are available in both metric and imperial sizes, featuring thread profiles including Unified National Coarse (UNC), Fine Pitch (UNF), and ISO metric. We manufacture these in all material types and ASTM specifications such as high-tensile alloys and high-polish stainless steel.
