M10-1.5 DIN 7984 Low Head Socket Cap Bolt Black Oxide Grade 12.9

Description

M10-1.5 DIN 7984 low head socket cap bolt commonly used in machine parts die fixturing and clamping. The socket head enables driving where there is not sufficient space for wrenches or sockets. Ever Hardware provides custom made fasteners and customizable packaging.

The hex socket screw drive has a hexagonal recess and may be driven by a hex wrench, also known as an Allen wrench, Allen key, hex key or inbus as well as by a hex screwdriver (also known as a hex driver) or bit. Tamper-resistant versions with a pin in the recess are available.

Black oxide or blackening is a conversion coating for ferrous materials, stainless steel, copper and copper-based alloys, zinc, powdered metals, and silver solder. It is used to add mild corrosion resistance, for appearance and to minimize light reflection. To achieve maximum corrosion resistance the black oxide must be impregnated with oil or wax. One of its advantages over other coatings is its minimal buildup.

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.

12.9-grade M10-1.5 DIN 7984 low head socket cap bolt has 12X100 N/mm^2 tensile strength and 9 is a multiplier means 80% of 1200 = 1080 N/mm^2 is the yield strength of the grade.
Similarly, we also have grade 6.8, 8.8, 10.9, also. This is an imperial method implied by engineers to differentiate between different sets of steel grades. Mainly used to differentiate the bolts and nuts. Like Grade 12.9 Hexagonal Bolt.
