Flat Set Grub Screw is composed of thread, driving groove, and flat end. It is connected by thread, driven by a large torque groove, and positioned by the friction force between its end plane and machine parts. The flat set grub screw is generally made of carbon steel, stainless steel, non-ferrous metal, or non-metallic materials. The drive groove type is usually slotted and hexagonal, and the thread system includes the metric system and the British system. NOTE: When locking the set screw, please choose a suitable wrench and apply a suitable force to avoid sliding grooves and the inability to disassemble. Cone-pointed set screws generally used in places that do not need to be disassembled frequently after installation, and are suitable for parts with less rigidity. Cone-pointed set screw (unpointed): it is necessary to drill a hole on the tightening surface of the part first, so that the conical surface is pressed against the edge of the hole to enhance the load transmission capacity. It is suitable for parts with greater hardness.Flat point set screws: mostly used in connections that require frequent adjustments, and the transfer load is small. The flat point has a large connected area and can be used for parts with high hardness, and the connected surface needs to be flat.Cylinder point set screws: used in places that require frequent adjustments. It can transmit large loads. There should be a device to prevent loosening when using these screws.
