Stainless steel screws provide unmatched benefits over standard steel screws thanks to their superior durability, high strength, and excellent corrosion resistance. This makes stainless steel an ideal screw material for applications demanding weather and rust resistance as well as longevity under stress.
Stainless steel screws come in a wide selection of head styles and drive types to accommodate various assembly and fastening needs.
Stainless steel screws are also available with different thread configurations for different purposes.
In addition to drive type and threads, stainless steel screws come in a number of head styles to suit various needs.
Stainless steel screws can also receive a number of different coatings to augment their corrosion resistance with additional properties.
The most common grades of stainless steel used for screws include 304 and 316. 304 stainless offers a good balance of decent corrosion resistance paired with adequate tensile strength for many applications. 316 stainless contains more nickel for enhanced resistance to chlorides and marine environments. When very high strength is needed, 410 stainless can be heat treated and hardened to achieve impressive tensile strength levels rivaling some alloy steel grades.
With their unparalleled combination of corrosion resistance, high strength, and longevity, stainless steel screws clearly outperform regular steel, brass, or coated screws. Their excellent physical properties ensure durable, reliable fastening performance even when subjected to demanding outdoor conditions. Any application where weather resistance, rust prevention, and longevity are important benefits will stand to gain by utilizing superior stainless steel screws.
