Product principle
The plum blossom groove self tapping screw has the following significant advantages:
Good fastening effect: The groove design of the self tapping screw with a plum blossom groove is unique and has a plum blossom shape. This design ensures that when using a Phillips screwdriver to tighten screws, the force is evenly transmitted at a 15 ° angle into the inner Phillips groove, thereby more effectively transmitting the tightening torque. In contrast, the groove shape of the hexagon socket screw is hexagonal, and the torque force will be transmitted along 60 °. The tightening torque force is prone to spread outward, resulting in loss. Therefore, the plum blossom groove screw has a better fastening effect.
Reduce the risk of damage: The design of the plum blossom groove screw helps to reduce damage to the tool and screw head. Due to the contact between the tool and the groove surface, the plum blossom groove screw can effectively disperse stress, avoid stress concentration, and reduce the risk of damage to the tool and screw head. In contrast, when using hex screws, the tool only comes into contact with the six corners. When the tightening torque increases, the force will concentrate on the corners of the tool, which can easily cause damage to the hex parts of the tool and screw head.
Strong anti floating performance: The self tapping screws with plum blossom grooves have good anti floating performance. When tightening cross slot screws, if tools such as screwdrivers are not constantly pushed and pressed, the tools will float upwards, which is called the floating phenomenon. The floating phenomenon will reduce the tightness between the cross groove and the tool, resulting in damage to the tool and screw head. However, the plum blossom groove screw will not cause any floating phenomenon and can be tightened safely and firmly.
Easy installation: The installation of the plum blossom head self tapping screw is very convenient, without the need for pre drilling, it can be directly screwed into the wood, saving time and effort. This design is not only suitable for home decoration and DIY handmade production, but also widely used in home decoration, furniture assembly, wooden product repair and other scenarios. Its self tapping thread design makes the installation process simple and efficient, and the screw head is flush with the material surface, perfectly hiding the screw head and maintaining the overall beauty.
Aesthetics and Customization: Plum blossom head self tapping screws not only have a beautiful appearance, but also have the advantage of customization. Some plum blossom groove screws can be customized in appearance and color according to the product's usage needs, such as the CD patterned plum blossom screws used in mobile phones. This customized design not only meets the product's requirements for fastener appearance, but also improves the overall aesthetics and practicality of the product.
