3/8" x 1-1/2" USS HEX HEAD CAP SCREW - 316 STAINLESS STEEL

3/8"-16 x 1-1/2" 316 SS Hex Head Cap Screw

Hex head cap screw made from 316 stainless steel, an austenitic alloy which differs from 18/8 by its molybdenum content (2-3%) and higher nickel content (10-14%). The molybdenum content gives this type of stainless even greater corrosion resistance than 18/8 as well as superior strength at high temperatures.The austenitic alloys develop their strength through work hardening during the fastener manufacturing process.  The only heat treatment normally available on austenitic stainless alloys is annealing, which is done at approximately 1900°F to a dead soft condition and is not normally thermally reversible.
