Material
The matter from which a thing is made
Brass
Brass is a soft, non-magnetic fastener material that offers corrosion resistance, heat and electrical conductivity, and cosmetic appeal. Brass fasteners may be found in electronics, plumbing, and marine applications.
Nylon
Nylon is a lightweight, wear resistant, non-magnetic, non-conductive, corrosion resistant fastener material often used in electronics applications. Nylon fasteners are commonly made of nylon 6/6, which is generally able to withstand oils, greases, and solvents. Many nylons melt rather than burn and have the ability to self-extinguish. Nylon fasteners may swell from moisture absorption, degrade under UV exposure, or fail in high strength applications.
Stainless Steel
Stainless steel is steel combined with alloying elements, principally chromium, to enhance corrosion resistance and impart other desired properties depending upon the alloying elements in use and their proportions. Many stainless steel fasteners are non-magnetic or less magnetic than regular steel fasteners.
Steel
Steel is the most common fastener material due to its strength properties. Unalloyed steel may be surface treated to enhance corrosion resistance and other desirable properties.
