Grade 8 Socket Head Cap Screws Internal Allen DIN 912 Alloy Steel Fully

The grade 8 socket head cap screws are commonly used in machine parts, die fixturing, and clamping. The socket head enables driving where there is not sufficient space for wrenches or sockets.  cap screws are commonly used in machine parts, die fixturing, and clamping.

Heat treating is a group of industrial and metalworking processes used to alter the physical, and sometimes chemical, properties of a material. The most common application is metallurgical. Heat treatments are also used in the manufacture of many other materials, such as glass. Heat treatment involves the use of heating or chilling, normally to extreme temperatures, to achieve the desired result such as hardening or softening of a material. Heat treatment techniques include annealing, case hardening, precipitation strengthening, tempering, normalizing, and quenching. It is noteworthy that while the term heat treatment applies only to processes where the heating and cooling are done for the specific purpose of altering properties intentionally, heating and cooling often occur incidentally during other manufacturing processes such as hot forming or welding.

8.8-grade steel means that a component manufactured from this grade of steel has 8X100 N/mm^2 tensile strength and 8 is a multiplier means 80% of 800 = 640 N/mm^2 is the yield strength of the grade.
Similarly, we also have grade 6.8, 10.9, 12.9 also. This is an imperial method implied by engineers to differentiate between different sets of steel grades.
