Grade 8.8 Hex Flange Screw White Zinc Plating Machine Threaded

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.
Similarly, we also have grade 8.8, 10.9, 6.8 also. This is the imperial method implied by engineers to differentiate between different sets of steel grades. mainly used to differentiate the bolts and nuts. like grade 8.8 hex flange screw.

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. A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together.
