Metric to Imperial Grade Equivalents - Portland Bolt
WebGenerally, grade A4 stainless screws tend to be easier to fabricate, clean, finish, and weld. This is because the chemistry of A4 differs from A2. Moreover, the high alloying content makes it more expensive than grade 304 stainless steel. However, in consideration of the larger picture, these screws are an investment. WebGrade 5 – indicates medium carbon steel. Can be identified by searching for 3 radial lines on the head of a bolt. Grade 8 – indicates medium carbon alloy steel. Can be identified by searching for 6 radial lines on the head of a bolt. Grade A325 - indicates a carbon alloy steel with or without boron, and you would see ‘A325’ on the head ... cts tufted brush
