Description

(USPS 2-3 Day Priority Mail on orders over $40.00, ships same day). (Under $40.00 ships USPS First Class Package 2-9 days) (2 pc) extsw 1/2" ID x 1 1/2" OD x 1/4" thick 316 Alloy Stainless Steel Washer. .030 inch Radius OD / Countersunk ID (no sharp edges). Actual dimensions 1/2" ID (.502) x (1.490) 1 1/2" OD x 1/4" (.250) (+/- .003 on all dimensions). Made in USA on a CNC lathe. It is a beautiful fit for your 1/2" Stainless bolts. 316 Grade Alloy Stainless contains a higher percentage of nickel than 304SS. The resultant composition gives a much improved corrosion resistance in many aggressive environments. The molybdenum addition ensures more resistance to pitting and crevice corrosion in chloride-containing media, sea water and chemical environments such as sulfuric acid compounds, phosphoric and acetic acids. The lower rate of general corrosion in mildly corrosive environments gives 316 SS a good atmospheric corrosion resistance in polluted marine atmospheres. 316 SS offers good strength and creep resistance and also possesses excellent mechanical and corrosion-resistant properties at sub-zero temperatures.
