Product Description
Premium A4-80 (316) stainless steel hex standoff screws with blue-zinc plating. Available in sizes M3-M8. Offers superior corrosion resistance for industrial, marine, and chemical environments. Fully customizable dimensions.
Engineered for demanding environments, our premium Hex Standoff Screws are manufactured from A4-80 (316) Stainless Steel. This grade offers superior resistance to corrosion, particularly from chlorides and chemicals, making it ideal for harsh industrial, marine, and outdoor applications. The male-female threaded design provides versatile mounting and stacking solutions. Despite the enhanced material, we apply a blue-white zinc plating over the stainless steel for added corrosion protection and a consistent appearance with other components in your assembly.
