Stainless Steel Square Drive Pan Head screws have a flat surface under the head to ensure that they will not pull through softer materials, the way a flat head screw will.
These are ideal for attaching metal hardware that does not have a countersunk hole. Like the Stainless Steel Flat Head screws, use a slightly oversize pilot hole to avoid breakage. Note that these have a tapping-type thread, which increases the strength of the screw but reduces holding power compared to the deep thread.
Stainless Steel: No discussion of corrosion resistance would be complete without mention of stainless steel screws. Although all products corrode eventually, stainless steel continues to provide excellent protection. Stainless steel is a general term for a large group of alloy steel that contains at least 10.5% chromium. Since the carbon content of stainless steel is quite low, oxidation (rusting) is also quite low. However, since the carbon content is low, the steel cannot be heat-treated to adequate levels. As a result, the screws are soft and break easily when used in wood applications that require high torque. Pre-drilling all screw holes and using larger gauges of screws can compensate for this problem.
The Nickel used in manufacturing stainless steel makes them non-magnetic and will not hold to a magnetic bit.
18/8 grade stainless steel is one of the two most common grades used in food preparation, dining, and cookware. 18/8 stainless steel is comprised of 18% chromium and 8% nickel. 304 grade stainless steel contains no more than 0.8% carbon and at least 50% iron. Chromium binds oxygen to the surface of the product, protecting the iron from rust (oxidation). Nickel also enhances stainless steel's corrosion resistance. The higher the nickel content, the more corrosion-resistant the stainless steel is.
The second most popular type of stainless is Type 316. 316 stainless lowers the chromium content from 18% to 16%, and the nickel content is increased to 10% and 2% molybdenum is added to the mixture. The change in the chromium/nickel ratio, along with the addition of the molybdenum, increases the resistance to chlorides. This is why Type 316 stainless is recommended in more corrosive environments, such as oceanside and pools, where the material will be exposed to chemical, solvent, or salt water corrosion. This makes it the preferred material for marine construction.
Tapping Style Thread: Generally, the entire screw shank is threaded, which makes sense for a sheet metal screw, of course.
