Precision shoulder bolts grade 8 hex head shoulder screw nylon patch

Precision shoulder bolts ISO 7379 are cost-saving construction elements for a wide variety of different uses. The maximum tightening torque must not be defined by strength class 12.9, it is instead limited by the relatively small bearing points (shoulders) and by the recesses at the transition point from the diameter of the shoulder to the thread diameter and the diameter of the shoulder to the head diameter. Ever Hardware provides all kinds of precision shoulder bolts and customizable packaging.

Heat treating makes the precision shoulder bolts high strength. 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 precision shoulder bolts rusting. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc.
