PEI Ultem Hex Socket Cylinder Head Cap Metric Screws conforming to ISO 4762 are engineered for high-performance applications requiring excellent mechanical strength, thermal stability, and electrical insulation. Manufactured from Polyetherimide (PEI), these fasteners offer exceptional dimensional stability and retain their mechanical properties at elevated temperatures, making them suitable for demanding industrial environments.
Designed with a hex socket drive and cylinder head configuration, PEI screws ensure dependable fastening and easy installation in applications requiring lightweight, non-metallic hardware. Their inherent flame resistance, low smoke generation, and excellent dielectric properties make them ideal for aerospace, electronics, medical devices, and semiconductor equipment.
