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.
