Grade 8.8 hex flange screw is a hex flange head screw with grade 8.8 strength after heat treatment. 12.9-grade steel means that a component manufactured form this grade of steel has 12X100 N/mm^2 tensile strength and 9 is a multiplier means 90% of 1200 = 1080 N/mm^2 is the yield strength of the grade. Ever Hardware provides custom-made fasteners and customizable packaging.

A flange is an external or internal ridge, or rim (lip), for the strength of grade 8.8 hex flange screw, as the flange of an iron beam such as an I-beam or a T-beam; or for attachment to another object, as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera; or for a flange of a rail car or tram wheel. Thus flanged wheels are wheels with a flange on one side to keep the wheels from running off the rails. The term “flange” is also used for a kind of tool used to form flanges. Pipes with flanges can be assembled and disassembled easily.
A flange can also be a plate or ring to form a rim at the end of a pipe when fastened to the pipe (for example, a closet flange). A blind flange is a plate for covering or closing the end of a pipe.
