Product Name | Stainless Steel Hex Head Bolts |
Material | Made from 304 stainless steel, these screws have good chemical resistance and may be mildly magnetic. They are also known as A2 stainless steel. |
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 B18.2.1 or formerly DIN 933 specifications comply with these dimensional standards. |
