What are Hex Cap Nuts and what are they used for?
Hex Cap Nuts, also known as acorn nuts, are hexagonal fasteners with a domed top that covers the exposed end of a bolt or threaded stud. This design provides both protection against physical damage and corrosion while offering a clean, polished look. They are commonly used in automotive, electrical panels, furniture, and decorative applications where both function and aesthetics are important. The enclosed top also prevents thread exposure to contaminants and reduces injury risk.
Which materials are used in manufacturing Hex Cap Nuts?
Hex Cap Nuts are manufactured from carbon steel, stainless steel (grades 304, 316), and alloy steel to meet different mechanical and environmental demands. Carbon steel offers strength and cost-efficiency for general applications, while stainless steel variants are ideal for corrosive environments like marine, chemical, or outdoor settings. Alloy steel types offer additional tensile strength for heavy-duty applications. Material selection depends on project needs, including load, weather, and chemical exposure.
Are Hex Cap Nuts suitable for outdoor or corrosive environments?
Yes, especially when made from stainless steel or coated with zinc, chrome, or hot-dip galvanizing. These finishes improve corrosion resistance and extend the life of the fastener. Stainless steel cap nuts are preferred in outdoor, marine, and chemical environments, while zinc-plated ones offer moderate protection in general outdoor applications. Their closed top design also reduces moisture entry and contamination of threads.
