GB 71

Attributes:

GB/T 71 specifies slotted cone - point set screws with thread specifications ranging from M1.2 to M12. The length range varies according to different thread specifications. For example, the length range of M1.2 is 2mm to 6mm, and that of M12 is 14mm to 60mm. The property classes are 14H, 22H, 33H, 45H, etc., and different property classes correspond to different mechanical property indexes such as hardness. The material is usually high - quality alloy steel or stainless steel.

Features:

The slotted cone - point set screw has a unique design of slotted and cone - point. The slot is convenient for the insertion of tools, making it easy to tighten and disassemble. The cone - point can penetrate into the workpiece during the tightening process, providing additional friction and achieving a self - locking effect, which can maintain a stable connection under vibration conditions and has excellent anti - loosening performance. At the same time, it is made of high - quality materials, with good corrosion resistance and durability.

Applications:

It is widely used in mechanical, electronic, aerospace, rail transit, heavy - machinery and other fields. In CNC machine tools, it can be used to fix the transmission device and guide rail system. In electronic equipment, it can be used to fix circuit boards and other precision components. In the aerospace and rail transit fields, it can ensure the tight connection of key components under harsh conditions such as high vibration and high speed, providing a guarantee for the normal operation and safety of equipment.
