Stainless Steel Ball Bolts should have precise end-face pressure. By minimizing the thickness of the bushing pin head and using as long as possible a high-quality spring, it can reduce the fatigue of the spring and increase its service life. 

The height of the ball head of each plunger protruding from the plunger body must be uniform. Precise processing control and strict inspection procedures must ensure that the size difference between the protruding height of each plug ball head does not exceed 0.1mm. Some specifications cannot exceed 0.05mm. 

Although it can be installed with a screwdriver or an Allen wrench, most experts recommend using a special spring plunger wrench especially for novices. Use of the wrong tool to run the risk of over-compressed springs and damage. As any technician knows, you should always work with the right tools. The biggest danger during installation is that the plunger spring uses too much torque. Although they are like bolts or screws, their bodies are hollow, and there is a limit to the power they can tolerate.
