Download the PEI (Polyethylenimine) - Ultem
PEI Ultem Flat Head Metric Screws manufactured to ISO 7046 standards are high-performance engineering fasteners designed for applications requiring exceptional strength, thermal stability, and electrical insulation. Manufactured from Polyetherimide (PEI Ultem), these screws offer outstanding mechanical properties and dimensional stability, even in demanding high-temperature environments.
Featuring a countersunk flat head, these screws sit flush with the mounting surface to create a smooth, professional finish while ensuring reliable fastening. Their combination of strength and high-temperature performance makes them well suited for aerospace, electronics, medical devices, semiconductor equipment, and industrial applications where standard plastic fasteners may not meet performance requirements.
With excellent resistance to heat, creep, and many industrial chemicals, PEI Ultem flat head screws provide reliable long-term performance in critical applications while offering a lightweight, corrosion-resistant alternative to metal fasteners.
