EXTSW 5/16" ID x 1/2" OD x 1 3/8" long 316 Stainless Spacer Actual size .323” ID x .490” OD x 1.375” Long (+/- .003 on all dimensions)  .030 inch Radius OD / Countersunk ID (no sharp edges) Made in USA on a CNC lathe It is a beautiful fit for your 5/16" Stainless bolts or shafts   We can make as many as you need, just contact me.316 Grade Alloy Stainless contain 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.
