Stainless Steel Screws and Bolts
There are a lot of reasons to buy stainless steel screws and bolts, no matter what your fastening needs may be. Screws and bolts are everywhere, from the home, to vehicles and even industry. If you have two pieces of metal to attach together, you need something to fasten it, and bolts are a very common choice.Stainless Steel
Stainless steel is a name that actually refers to a number of different iron alloys with similar properties. Steel itself is an alloy of iron and carbon, which is so common that people often categorise it as a base metal that is then alloyed with others. Most stainless steel adds chromium and nickel to the mix, to give the anti-corrosion properties that make it such a sought-after material. It's strong, resistant to corrosion and easy to clean. It's also readily available.Stainless Steel vs. Coatings
The big advantage of stainless steel over coated alloys like galvanised steel is that the corrosion resistance is due to the metal itself, not a protective coating. That makes materials like stainless steel, and also aluminium, much less susceptible to minor scrapes and dings. Scratch galvanised screws or bolts and you've opened a doorway to corrosion. Scratch stainless steel, and you've done nothing of the sort.Fastener Examples
The biggest difference between a screw and a bolt is that a bolt needs a nut on the end and a screw doesn't. Bolts pass through the material and fasten on the far side, while screws are driven into the material and are held in place by the threads. Both bolts and screws come in a wide variety of styles and sizes for different uses.Screw Heads
While the shank and point are important, most categorise screws by the screw head, as that determines the tool you need to drive it. Phillips screws feature an X-shaped head, while Robertson screws have a square hole set into the centre. Stainless steel socket screws have the head in the form of a small cylinder, fitted with a socket drive in the centre.
