Fastening screw MTCH

automotivewith hexagonal headspanner

Product overview
Hexagon-head screw MTCH manufactured in PA66 and PA66GF30 (PA66 with 30% glass fibre). Suitable as a lightweight industrial alternative to metal hexagon-head screws where electrical insulation, corrosion resistance or reduced weight are required.

Main properties

• Thermal: PA66 continuous use up to 100 °C; PA66GF30 up to 120 °C.
• Mechanical: good tensile and shear performance; increased stiffness with glass-fibre reinforced option; stable dimensions.
• Chemical: resistance to oils, greases, hydrocarbons and common solvents.

Advantages over metal screws

• Lower weight compared to steel or stainless options.
• Corrosion resistant in aggressive environments.
• Electrically and thermally insulating.
• Non-magnetic, non-conductive and spark-free.
• Vibration damping and noise reduction.
• Reduced maintenance in corrosive or chemically active conditions.

Applications
Suitable for electrical equipment, electronics, automotive assemblies, construction components, HVAC systems and general industrial fastening tasks.
