Basic parameters:

Hardness:

Hexagon socket bolts are classified according to the hardness of the screw wire, tensile force, yield strength, etc., which is the grade of the hexagon socket bolt and what grade is the hexagon socket bolt. Different product materials require different grades of hexagon socket bolts to correspond to them.

Hexagon socket bolts have the following grades:

Hexagon socket bolts are divided into ordinary and high-strength according to their grade strength. Ordinary hexagon socket bolts refer to grade 4.8, and high-strength hexagon socket bolts refer to grades above 8.8, including grades 10.9 and 12.9.

Crafting process:

1. Drill holes according to the diameter of the opposite side of the inner hexagon to the requirements.

2. Upsetting the inner hexagon with a cold heading machine.

3. A single piece can be punched out with a hexagonal punch.
