Thermoplastics - reference values of physical characteristics

Instructions for screws made of thermoplastic materials

• Mechanical and physical properties, especially tensile strength and preload as well as colour, tolerances of threaded section and head geometry are subject to climatic conditions. Consult DIN 34810 and ISO 4759-1 for tolerance values, advice and assembly torques.
• Preload can fall via stress relaxation. Instructions for construction and design are to be followed on the basis of VDI 2544.
