Stainless steel is steel that has been engineered to be as rust-proof as possible. Stainless steel screws retain the same rust-proof ability, too. If you are wondering just what people use stainless steel screws for, and whether or not they will work on your next metal project, here are some examples where these screws are a must:
Stainless steel screws, pins, and bolts are used in surgical procedures, such as helping stabilize numerous fractures of your arm or leg. The screws, pins, or bolts help the body repair itself and return your smashed limb back to its best post-trauma self. Because these stainless steel fasteners do not rust, and because they reinforce and support damaged bones, they will not poison patients with metals while the patient heals.
Planes, trains, boats, and automobiles may all have some areas that are exposed to the elements. When those areas require screws to hold together and nothing else will cover or shield these areas, the screws have to be stainless steel. The stainless steel ones have to hold up, despite the constant pressure of air in a plane, train, or automobile. They also have to withstand tons of water when they are holding a boat together. The strength of stainless steel works best in all of the above.
Metal Artist's Works
Unless a metals artist wants rust to become part of the sculpture, he or she will use stainless steel everything in what they do. The sculpture stays the intended and chosen metal color. If the artist intentionally wants the piece to be outdoors and covered in a rusty patina, then the artist will use whatever metal fasteners are available. If you have a metal sculpture with screws in it, you may want to be careful about placing it outside without verifying if the screws are stainless steel or some other type of metal.
Many landscaping tools are electric or operate on gas. Either way, the screws used in these tools should be stainless steel. First and foremost, stainless steel does not conduct electricity, which makes electrical landscaping tools much safer to use. Second, landscapers could injure themselves on these tools, and rust leads to lockjaw, a condition that locks the mouth in a closed position for several days. If the screws are stainless steel, they cannot rust, and the landscapers cannot scrape rust into any wound they might acquire.
