Screws For Metal Sheet Hardened Thread Cutting Metal Plate Screws

Screws for metal sheet is the screw with flat end self tapping and cutting thread, the screws are usually with heat treating to makes the screws hardened. Thread cutting screws are a class of self-tapping screw that create threads in existing holes in metal and are often used as fasteners in items that need periodic maintenance.
Thread cutting, as compared to thread forming and rolling, is used when full thread depth is required, when the quantity is small, when the blank is not very accurate when threading up to a shoulder is required, when threading a tapered thread, or when the material is brittle. Tapping screws form mating threads in materials they are driven into. There are two basic types: thread forming and thread cutting. The thread-forming screw displaced material around the pilot hole so that it flows around the screw’s threads. Ever Hardware provides custom-made fasteners and customizable packaging.

Heat treating makes the screws for metal sheet high tensile. 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.
