Phillips Key L Type Handle Cross Wrench Screwdriver Hardened Galvanizing

Phillips key or phillips screwdriver or cross wrench is which you’ll use often but mostly in places where the screw head is hidden from sight. The crosshead style of screw is best suited for power driving. Phillips and posidrive screws are two types of crosshead screws, different from each other in that the Phillips screw head has four cross points and the posidrive screw head has a star with eight points. Ever Hardware provides custom-made fasteners and customizable packaging.

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.

Galvanization, or galvanisation, (or galvanizing as it is most commonly called in that industry), is the process of applying a protective zinc coating to steel or iron, to prevent Phillips key rusting. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc.
