Metric Hex Flange Head Machine Screws
|Publication Date:||1 May 2011|
This standard for Metric Hex Flange Head Machine Screws conforms in all essentials with the American National Standard covering metric machine screws. It should be noted that the hexagon widths on these screws differ from those on the corresponding sizes of hex and hex washer head screws and, therefore, the wrench sizes will be affected accordingly.
