Stainless Steel Dome Nuts

Product Price :

Yellow Enterprises, Pune (est. 2017) manufactures precision stainless steel dome nuts designed for robust fastening applications. Made from superior corrosion-resistant stainless steel, our dome nuts offer clean aesthetics and high performance. Ideal for industrial, automotive and architectural use, available in multiple grades and sizes.

Dome nuts (also known as cap nuts, acorn nuts or blind nuts) feature a domed end which encloses the exposed thread of a bolt or stud. This design provides both functional and aesthetic benefits: the rounded cap protects nearby surfaces and human contact from sharp threads, while giving a smooth, finished appearance.
Our stainless steel dome nuts are manufactured to stringent standards, covering thread sizes (metric M2–M60, UNC/UNF equivalents), and conforming to norms such as DIN 1587, DIN 934 etc.
By selecting premium stainless steel grades (e.g., 304, 316, A4), Yellow Enterprises ensures excellent resistance to corrosion, weathering, and harsh industrial environments.

Key Features & Benefits

Corrosion Resistance & Durability: Manufactured from high-grade stainless steel, our dome nuts maintain mechanical integrity and appearance in corrosive or marine environments. For example, stainless steel dome nuts in A4 grade are described as “marine-grade … that has excellent resistance to corrosion and is suitable for almost any environment.”
Thread Protection & Safety: The domed design safely encloses the exposed end of the bolt or stud, preventing injury, reducing snagging, and avoiding damage to adjacent components.
High Performance in Dynamic Environments: Suitable for applications subject to vibration or movement, our dome nuts ensure the thread end is covered and less likely to deteriorate or loosen.
Aesthetic Finish: The domed-cap provides a clean, finished look—ideal for architectural fixtures, furniture, automotive wheel covers and visible fastenings.
Versatility in Sizes & Grades: Yellow Enterprises offers dome nuts in a wide range of sizes and grades. From small M2 to large M60 threads, in stainless steel 304/316/904L etc., we cater to standard and custom requirements.

Our stainless steel dome nuts find extensive use across industries:

Automotive & Wheels: Covering exposed stud threads, offering both safety and finish on wheel assemblies, exhaust systems, accessories.
Marine & Offshore: In salt-water environments, A4 stainless dome nuts provide outstanding corrosion resistance.
Construction & Architecture: For visible fastenings on façades, railings, fixtures where aesthetics matter.
Electrical & Control Panels: Dome nuts prevent contact with sharp threads and offer a clean look on enclosures.
Industrial Machinery & Equipment: In conveyors, processing units, heavy-duty applications where exposed threads must be protected.
