GB12 Square Neck Screws
A screw is a mechanical part, a fastener with threads, usually consisting of a head and a screw. The screw has threads, and by rotating the screw, it can be screwed into the workpiece to achieve the function of fastening or connection. It is mainly used to connect, fix, or adjust two or more objects. Some screws (such as adjustment screws) can be used to adjust the position or gap of parts.
Key Features
- GB12 Square Neck Screws are high-quality industrial fasteners designed for secure and reliable connections in demanding applications. These screws feature a distinctive square section beneath the head, which locks positively into a corresponding square hole in the mating part. This design prevents rotation during assembly and tightening, ensuring a vibration-resistant and stable joint.
Manufactured to relevant GB (Chinese National Standard) specifications, they offer excellent strength and durability. The square neck provides superior torque transmission compared to standard screws, making them ideal for use in assemblies where high clamping force is required and where screw head rotation must be absolutely prevented.
