20pcs High-Temp PEEK Screws – M2.5/M3/M4 Hex Socket Allen Head DIN912

20pcs PEEK Hex Socket Screws – High-Temperature Allen Head Plastic Bolts M2.5/M3/M4 (DIN912)

Engineered for Demanding Applications — Lightweight, Heat-Resistant, Corrosion-Proof Fastening

Looking for high-performance fasteners that outperform metal screws in high-temperature, chemically aggressive, or non-conductive environments? Our 20pcs PEEK Hex Socket Screws offer exceptional durability, electrical insulation, and chemical resistance — ideal for electronics, aerospace, medical devices, and custom manufacturing.

Each screw is made from premium-grade PEEK (Polyether ether ketone) and follows DIN912 Allen head standard, available in M2.5, M3, and M4 thread sizes with assorted lengths ranging from 6mm to 35mm (0.24"–1.38").

🔧 Key Benefits of PEEK Hex Socket Screws

High-Performance Engineering Material

Made from 100% pure PEEK plastic, these screws resist temperatures up to 260°C (500°F), maintain dimensional stability under load, and withstand chemical corrosion, steam, saltwater, and solvents.

Non-Metallic and Insulating

Ideal for RF-sensitive and electrically isolated environments. Perfect alternative to metal screws in applications requiring non-conductive, X-ray transparent, or MRI-compatible fasteners.

Multiple Sizes and Colors

Choose from M2.5, M3, or M4 screws with multiple lengths to suit your assembly. Each pack includes 20 pieces in assorted colors (black, white, red, blue, green, yellow), or request custom quantity, length, or color combinations to fit your unique needs.
