Technology / product information

CHEMIS PEEK/(-)BT Hex Bolts are made from high-performance PEEK material, designed for extreme conditions involving heat, chemicals, and electrical insulation. Ideal for critical industries such as electronics, medical devices, chemical processing, and food manufacturing.

These hex bolts are engineered using Polyetheretherketone (PEEK), a high-grade engineering plastic known for outstanding durability and non-conductive, non-magnetic properties. Their robust design and resistance to aggressive environments make them suitable replacements for metal fasteners.
