Hexagon head non-ejectable bolts GB838, also known as hexagon head non-stripping screws, are unique in that the head of the bolt is hexagonal, making it easy to install and remove using tools such as spanners. The bolt body is partly threaded and girdled, and the diameter of the girdled section is smaller than the small diameter of the thread, which makes the bolt able to be clamped in the mounting holes of the connected parts after installation, and effectively prevents the bolt from loosening or falling off.
GB838 bolts are usually made of high-strength alloy steel material, and the hardness level can be up to 12.9, which can meet the needs of various high-load connections. In addition, the surface of the bolt is plated with blue and white zinc, which not only improves the corrosion resistance of the bolt, but also increases its aesthetics.
Unique advantages of Excellent anti-dislodgement performance: thanks to its unique girdle design, GB838 bolts are able to maintain a stable connection in vibration or shock environment, effectively preventing the bolt from loosening or falling off, ensuring the safe operation of the equipment or structure.
Installation Convenience: The hexagonal head design makes the installation and dismantling process of the bolt easier and quicker, which improves the working efficiency. At the same time, the standardised size specification is also easy to match with different brands and models of nuts.
Wide applicability: GB838 bolts are suitable for a variety of materials and structures, including metal, non-metal and composite materials. Its high strength and excellent anti-dislodgement properties make the bolts have a wide range of applications in various fields.
