The characteristics of plum blossom screws

I believe everyone is familiar with plum blossom screws, also known as internal plum blossom screws, commonly found in brake systems, hard drives, computer systems, and consumer electronics products of automobiles, motorcycles, and bicycles. Next, follow in the footsteps of screw manufacturers to learn about the characteristics of plum blossom screws and why they are used?

According to the design, the deviation of the protrusion of the plum blossom screw may be due to a cross or a straight line. Its design is designed to simulate the deviation of the protrusion of a screwdriver. This design comes from the automatic torque control screwdriver used in the factory, which can stably provide a predetermined torque and reduce the risk of the screwdriver, screw head or workpiece.

2. The contact angle of a plum blossom screw design is closer to 90 degrees than that of a hexagonal head, so under the same torque, the potential destructive radial force will be much smaller. This feature allows the screw head to be made very small under the same torque, with the advantage of reducing space. However, the disadvantage of older synchronizers is that the smaller the "star shaped" shape, the more susceptible it is to corrosion and can cause the screwdriver to slide and damage the head, making it more difficult to remove than traditional hex screws. There is also a type of anti-theft screw that is mostly used for plum blossom with a pillar in the middle, which can prevent the penetration of plum blossom screwdrivers or ordinary screwdrivers and provide protection.
