Unlike a standard hex nut, the acorn nut provides a finished, decorative appearance while also protecting threads from dirt, damage, and corrosion. The 304 grade stainless steel ensures excellent rust resistance for long-lasting performance.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Which metric thread sizes do these acorn cap nuts come in?\u003c\/h4\u003e\n\u003cp\u003eA: These acorn nuts are available in M3, M4, M5, M6, M8, M10, and M12 metric thread sizes, covering the most common bolt diameters used in furniture, automotive, woodworking, and general hardware applications.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Are these stainless steel cap nuts suitable for outdoor or marine use?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! Grade 304 stainless steel offers strong resistance to corrosion and rust, making these domed cap nuts a great choice for outdoor furniture, railings, garden structures, and light marine applications where exposure to moisture is a concern.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I choose the correct acorn nut size for my project?\u003c\/h4\u003e\n\u003cp\u003eA: Match the acorn nut's thread designation (M3, M4, M5, M6, M8, M10, or M12) to the diameter of the bolt or threaded rod you are using. For example, an M6 bolt requires an M6 acorn nut. If you are unsure, measure the outer diameter of your bolt thread in millimeters — the number in millimeters corresponds directly to the metric size designation.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is a 304 stainless steel acorn nut and what makes it different from a regular hex nut?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"A 304 stainless steel acorn nut (also called a domed cap nut) features a rounded, dome-shaped top that covers the exposed end of a bolt or threaded rod.
