Natural PEEK Hex Socket Thread Cap Cylinder Head Screw With Density 1.31
High temperature resistance Hydrolysis resistant peek screw
PEEK screws are high-performance engineering plastic screws. PEEK (polyetheretherketone) has excellent high temperature resistance, corrosion resistance, and wear resistance. This type of screw has high strength and can maintain stable performance in harsh environments. It can maintain good mechanical strength in high temperature environments, while also having good insulation and low friction coefficient. PEEK screws are widely used in aerospace, medical, electronics and other fields, which can replace metal screws, reduce weight, and lower costs. Its excellent chemical stability enables it to resist corrosion from various chemical substances, making it a reliable connecting component.
