DIN 933 hex bolt made from A4 (V4A) stainless steel with high corrosion resistance. This professional-quality fastener is designed for stable mechanical connections and provides reliable protection against aggressive environmental influences. The bolt has a full thread extending to the head, making it suitable for tight connections. The A4 stainless steel is acid-resistant and seawater-resistant, making it suitable for boatbuilding, the chemical industry, coastal outdoor areas, and pool construction. It offers long-lasting performance without rust formation, even when exposed to saltwater or acids. Why choose A4 stainless steel instead of A2? A2 (V2A) stainless steel is generally used outdoors, while A4 offers additional resistance due to its molybdenum content. A4 is significantly more resistant to aggressive acids and chemicals and provides lasting protection against pitting caused by saltwater. It is also suitable for projects in or around pools, where chlorine can attack A2 screws over time. If your construction is exposed to severe weather, salt, or chemicals, A4 stainless steel is the safer choice for helping prevent rust damage and costly rework.
