PEEK Allen CSK Screw – DIN 7991 (Countersunk Head)
Product Description
PEEK Allen CSK Screws (DIN 7991) are high-performance, non-metallic fasteners with a precision-engineered countersunk head and internal hex drive. Crafted from PEEK (Polyether Ether Ketone) — a top-tier engineering thermoplastic — these screws provide exceptional strength, heat resistance, and chemical stability, making them ideal for demanding industries such as aerospace, medical, and semiconductor manufacturing.
Designed to sit flush with the surface after installation, these screws are perfect for applications where streamlined design, corrosion resistance, and non-conductivity are essential.
Applications
PEEK CSK Screws are widely used in:
Aerospace Interiors & Avionics Panels
MRI-Compatible Medical Equipment
Semiconductor Wafer Handling & Robotics
3D Printing and Motion Mechanisms
Cleanroom Automation & Lab Tools
Chemical-Resistant Surface Mounting
