Embodiment 1
[0012] A high-strength corrosion-resistant plastic screw, comprising: a screw shank, a screw head integrally connected with one end of the screw shank, a locking disk head set on the other end of the screw shank, and the screw shank is integrally processed There is an external thread structure, and the locking disc head is provided with an internal thread structure matching the external thread structure; the screw rod, screw head and locking disc head are all made of high-strength corrosion-resistant plastic Processed, the high-strength corrosion-resistant plastics include raw material components and their mass ratios: 60% PA6, 26% glass fiber, 9% nano-silica, and 5% nano-alumina.
[0013] Wherein, the screw head is cylindrical, and a cross-shaped groove is opened in the middle of the upper end surface of the cylindrical screw head.
[0014] The lower end plane of the screw head is integrally processed with a flange, which avoids tooth slipping during the tightening process an...
