Stainless Steel Acorn & Cap Nuts

Stainless steel acorn and cap nuts are essential fasteners used in various applications to secure bolts or screws while providing an aesthetically pleasing finish. Available in both inch and metric sizes, these nuts offer versatility to accommodate different thread specifications.

Acorn nuts, also known as crown nuts, are characterized by their domed shape, resembling an acorn. They have a closed end, which covers the exposed end of a bolt or screw, offering protection against accidental contact and providing a neat appearance. Cap nuts, on the other hand, have a flat top surface, similar to a regular hex nut, but without the internal threading.

These nuts are commonly manufactured using stainless steel alloys, such as 304, 316, or A2-70. Stainless steel is chosen for its corrosion resistance, durability, and ability to withstand harsh environments. The different grades offer varying levels of corrosion resistance, with 316 stainless steel being the most resistant to corrosive elements, making it suitable for marine and highly corrosive environments. Grade 304 stainless steel is widely used in general-purpose applications, offering good corrosion resistance in most conditions. A2-70 is a designation for stainless steel alloyed with a composition of approximately 17% chromium and 8% nickel, providing moderate corrosion resistance and high tensile strength.

Stainless steel acorn and cap nuts find applications in various industries, including automotive, construction, marine, and outdoor equipment. They are commonly used in situations where aesthetics, corrosion resistance, and secure fastening are important considerations. Whether you need inch or metric sizes, and whether you require the higher corrosion resistance of 316 stainless steel or the general-purpose capabilities of 304 or A2-70 stainless steel, there are options available to meet your specific needs.
