Product Details
Our Stainless Steel DIN 934 Hex Nuts are engineered to meet the highest standards of performance and reliability.
- Premium Stainless Steel Grades for Specific Environments: We offer two primary grades to suit different application needs:
- A2-70 (Type 304 Stainless Steel): This is the most common and versatile grade of stainless steel. It offers excellent corrosion resistance in a wide range of atmospheric environments and is suitable for most general-purpose applications. With a minimum tensile strength of 700 MPa, it provides a strong and reliable fastening solution for machinery, construction, and automotive use.
- A4-80 (Type 316 Stainless Steel): Known as “marine grade,” this steel contains molybdenum, which provides superior resistance to chlorides and other harsh chemicals. It is the ideal choice for marine, coastal, and chemical processing environments. With an enhanced minimum tensile strength of 800 MPa, A4-80 nuts deliver exceptional performance and security in the most demanding conditions.
- DIN 934 Standard for Universal Compatibility: All our nuts are manufactured in strict accordance with the DIN 934 standard. This ensures uniform hexagonal dimensions, thread profiles, and tolerances, guaranteeing a perfect, secure fit with any standard metric stainless steel bolt or stud.
- Polished Finish for Aesthetics and Cleanliness: The nuts feature a clean, polished finish that is not only aesthetically pleasing but also enhances the material’s natural corrosion resistance. The smooth surface is easy to clean, making these nuts ideal for hygienic applications in the food, beverage, and pharmaceutical industries.

Product Features
Our Stainless Steel DIN 934 Hex Nuts are the superior choice for their inherent quality and performance.
- Inherent Corrosion Resistance: Made from stainless steel, these nuts do not require any coating for protection. They will not rust or corrode, ensuring a long, maintenance-free service life.
- High Strength and Durability: With A2-70 and A4-80 grades offering tensile strengths of 700 MPa and 800 MPa respectively, these nuts provide robust and secure clamping force for critical joints.
- Wide Temperature Range: Stainless steel maintains its strength and integrity across a broad spectrum of temperatures, from cryogenic levels to elevated heat.
- Hygienic and Non-Reactive: The clean, non-porous surface of stainless steel makes it ideal for applications in food processing, medical equipment, and pharmaceutical manufacturing.
- Standardized for Guaranteed Fit: Full compliance with the DIN 934 standard ensures interchangeability and a reliable fit with standard metric bolts and wrenches.
Product Applications
The exceptional properties of stainless steel make these nuts essential for a vast array of demanding applications.
- Marine and Coastal Construction (A4-80): The definitive choice for boat building, docks, piers, and any structure exposed to saltwater spray and high humidity.
- Chemical and Processing Plants (A4-80): Used extensively in environments with exposure to acids, chlorides, and other corrosive chemicals.
- Food and Beverage Industry (A2-70 / A4-80): Ideal for machinery and equipment in food processing and commercial kitchens due to their hygienic properties and resistance to cleaning agents.
- Architectural and Structural Applications (A2-70): Used for balustrades, facades, and structural connections where both strength and a clean, aesthetic appearance are desired.
- Medical and Pharmaceutical Equipment (A4-80): The preferred fastener for manufacturing and assembling equipment that requires sterilization and resistance to aggressive cleaning solutions.
- General Outdoor Use (A2-70): Perfect for outdoor furniture, playground equipment, and general construction where long-term weather resistance is needed.
