The addition of molybdenum to the alloy of chromium and nickel gives the marine grade 316 stainless steel screws a much sought after resistance to salt solutions and brine as required by ships and boats encountering marine environment. Close to grade 304 in terms of popularity, the corrosion resistance of 316 stainless steel socket head cap screws is much higher, as are the mechanical properties. This molybdenum bearing 316 stainless steel self drilling screws are much more expensive than grade 304.
But the higher cost is justified as it offers much more advantages over grade 304. Used for woodwork, the head of grade 316 stainless steel countersunk screws will sit below the surface of wood, following its fastening the surface can easily be filled with a wood plug or filler. Grade 316 stainless steel grub screws are also referred to as a set screw. A4 Stainless Steel Grub Screws can be used to fasten an object within or against another object, usually without the use of a nut. 316 stainless steel screws also exhibit superior resistance to pitting. At elevated temperatures, the A4 Stainless Steel Self Tapping Screws offers properties such as higher creep, stress-to-rupture, and higher tensile strength. As typical behaviour of austenitic grades, the A4 Stainless Steel Coach Screws demonstrate excellent fabricability and formability.
