What is SAE J429 Grade 8 Fasteners ?

The SAE J429 Grade 8 Fasteners are made up of medium carbon alloy with the help of heat treating procedures. These are quenched and tempered. These fasteners are fabricated in such a way that they are able to possess the characteristics such as high tensile strength and yield strength.

The crews made from these SAE J429 Grade 8 Fasteners are considered one of the toughest fasteners. These are used in applications where withstanding a large amount of load is required. These fasteners are one of the first fasteners that were engineered. They are made up of ardent steel. These fasteners are used in a lot of critical applications.
