What about the strength of stainless steel screws than ordinary 8 grade black screws or zinc screws?
From the strength point of view, 8 bolts larger, tensile strength of more than 800MPa, stainless steel only more than 700MPa, from the actual use is not much difference. You are good for outdoor or stainless steel. Stainless steel is corrosion resistant and will not rust. Zinc plating will rust in one or two months if it is used outdoors.
This depends on the grade ah, stainless steel also has C series 1100 tensile strength, than the 10.9 grade screw strength is high, of course, the performance is high strength and toughness, but the price is expensive. Rustproof.
Stainless steel also has 8 levels
