There are several commonly used screw slots for screw fasteners, including cross slot screws, hexagonal slot screws, slotted screws, eleven-slot screws (plus and minus slot screws), hexagonal slot screws, and some uncommon triangular slot screws, hexagonal screws with columns, hexagonal screws with columns, pentagonal screws, etc. How should we choose from so many slots when using them? What are the characteristics of each slot?
Slotted screws Cross-slot screws Hexagon socket screws Hexagon socket screws The groove of the hexagon socket screw is in the shape of a flower. When using a hexagon screwdriver to tighten the screw, the force will be evenly transmitted to the groove of the inner hexagon at 15°, which can more effectively transmit the tightening torque.
The groove of the hexagon socket screw is hexagonal. When using the tool, its torque force will be transmitted along 60°, and the tightening torque force will spread outward, resulting in loss. The contact between the tool and the groove surface of the hexagon socket screw effectively reduces the damage of the tool and the screw head. There is no stress concentration, which will reduce the risk of damage to the tool and the screw head.
When using the tool, only the six corners of the hexagon socket screw are in contact. When the tightening torque increases, the force will be concentrated on the corners of the tool, and the hexagonal part of the tool and the screw head may be damaged.
Hexagon socket screws are widely used in electronic appliances and home appliances. They are often used for the connection and tightening of the inside and outside of the product. Some hexagon socket screws will be customized with different appearances and colors according to the use of the product. For example, the CD-threaded Torx screws used in mobile phones are commonly used to connect and fasten mobile phone shells.
