ISO 4026 black zinc plated hexagon socket flat end set screws

 

he set screw is used as the relative position of the fixed part.
 
The head has a type of slotted, hexagonal and square heads:
 
Square head - can apply a large tightening torque, the top tightening force is large, it is not easy to twist bald, but the head size is large, it is inconvenient to be buried in the parts, unsafe, especially the moving parts should not be used;
 
Slotted slot - easy to sink into parts. The screw tightening force is small, and it is often easy to screw off;
 
Hexagon socket - easy to sink into parts. More commonly used.
 
The end of the set screw is different according to the requirements of use. Generally, the most commonly used ones are tapered end, flat end and cylindrical end:
 
Cone end - suitable for parts with low hardness; when using a tipless conical screw, make a hole on the top surface of the part, and the cone surface is pressed on the side of the pit.
 
Flat end - large contact area, does not hurt the surface of the part after tightening, used to tighten the surface with high hardness or often adjust the position.
 
The cylindrical end—does not damage the surface of the part. It is often used to fix the parts mounted on the tube shaft (thin-walled part). The end of the cylinder end is inserted into the hole on the shaft. The anti-shearing action of the cylindrical end can transmit a large load.
