Big flat head glue check screw

By means of special technology, special engineering resin can be permanently adhered to the screw teeth, and the reverse elasticity of engineering resin material can be used to make the bolt and nut reach the absolute resistance to vibration and impact through extrusion in the locking process, which can completely solve the problem of screw loosening.The thread surface has been treated with anti-loosening treatment, which greatly enhances the anti-loosening property of screws.Often used in vibration or mobile devices or supplies such as cars and mobile precision electronic products, such as laptops, mobile phones.
