Product Description

Commodity	A2-70 Stainless Steel Hex Head Bolts
Material	Made from 304 stainless steel, these screws have good chemical resistance and may be mildly magnetic
Head Type	Hex Head.
Length	is measured from under the head.
Thread Type	：Coarse Thread, Fine Thread.Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch. Fine and extra-fine threads are closely spaced to prevent loosening from vibration; the finer the thread, the better the resistance.
Standard	Screws that meet ASME or ISO (formerly DIN) specifications comply with these dimensional standards.
