DIN 961 – 1990 Hex Head Cap Screws

DIN 961 Hexagon Head Cap Screws / Bolts are externally threaded fasteners with a hexagonal washer faced head

and a chamfered tip to facilitate mating with an internally threaded component.

All measurements in millimeters (mm)

Hexagon bolts are mainly used on mechanical equipment more frequently, and their main function is to connect. Once a fracture problem occurs during use, it will naturally affect the performance of the mechanical equipment and cause the mechanical equipment to fail to operate. Let’s take a look at how to prevent external hexagon bolts from breaking:

1. When using, you should choose matching outer hexagonal bolts. If the bolts and the connecting materials do not match, it is easy to cause breakage.

2. When assembling, it is necessary to control the force and tighten according to the specified standards. The tightening force is too large or too small, it is easy to cause the bolt to break, if it is too small, it cannot be tightened firmly. It is recommended to use a torque wrench as a tool when assembling.

3. When the mechanical equipment is running for a period of time, you need to check the usage of the outer hexagonal bolts. If the bolts are found to be loose, they need to be tightened. If the bolts are aging, they need to be replaced in time.

4. Every time you use it, you need to check the guiding part of the outer hexagonal bolt. There are cracks on the head and thread, and observe whether the pitch and shape of the thread are normal. If there is an abnormal condition, it cannot be used.
