What is A2 hardware?
A2 stainless steel fixings are made from an alloy containing a mixture of two or more metals. The steel within the fixing must contain at least 10.5% chromium to be considered or called stainless, and this chromium makes the metal more corrosion resistant and less likely to stain than other steels.
What is Grade a2-70 stainless steel bolt?
The Stainless Steel Bolt Grade A2-70 is cost effective, strong, hard and general corrosion resistant as well. The size of the bolts range from ¼ inches to 24 inches and these bolts are used in different application needs.
What is the difference between grade a nuts and bolts?
