Machine Screws Stainless
Stainless Steel Machine Screws are a straight shank fastener with external threads designed to go through a hole or nut that is pre-tapped to form a mating thread for the screw.
Stainless steel is superior to steel in withstanding some elevation in application operating temperature while maintaining its strength.
Made from one of the following austenitic alloys: 303, 303Se, 304, or XM7, all of which are characterized as having chromium content of 17-19% and nickel content of 8-10%. 18-8 stainless is used in products that require general atmospheric corrosion resistance.
316 or A4 stainless screws are made from austenitic alloy which differs from 18-8 by its molybdenum content (2-3%) and higher nicket content (10-14%). This molybdenum content gives 316 stainless even greater corrosion resistance that 18-8, as well as superior strength at high temperatures.
