What is the best Screw to buy?
Steel screws for outdoor use require a zinc or hot-dipped galvanized coating to protect against corrosion.
Decorative finishes like chrome, brass, or nickel plating offer some corrosion protection but are best used indoors. Other screw materials include stainless steel, brass, bronze and aluminum.
What to consider when buying a Screw?
Consider the material you are screwing into. Self-tapping screws are suitable for fixing sheet metal to softwood or plastic, and self-drilling screws are best for sheet metal to steel.
Consider the thickness of the metal sheet you are attaching, as each screw is suitable for a specific thickness.
What is the standard size of a Screw?
Examples: 4 mm x 0.7; 5 mm x 0.8; and 6 mm x 1.0. U.S. standard numbering systems list diameter sizes 0, 1, 2,3, 4, 5, 6, 7, 8, 9, 10, 12, 14,
and 16, and fractional sizes from 1/4″ to 2″ in 1/16″ increments, followed by a dash and the threads per inch (from about 6 to 80), and the length.
What is Screw made of?
The most common type of material for screws is stainless steel due to its inexpensive material. Other materials include copper,
aluminum, and titanium. Screws are coated for protection and strength. The coating can include copper, zinc, and ceramic coating.
