Our MTC hexagon domed cap nuts, similar to DIN 1587, are available in PA66 and PA66GF30, providing lightweight, insulating and resistant solutions for industrial and technical applications. Some references include a self-locking feature.

· PA66: High rigidity, good dimensional stability and resistance to wear, impact and fatigue. Continuous operating temperature up to 100 °C. Good resistance to oils, greases, hydrocarbons and aliphatic solvents.
· PA66GF30: Material reinforced with 30% glass fiber for increased mechanical and thermal resistance. Continuous operating temperature up to 130 °C with high resistance to deformation under load.

Suitable for electrical components, plastic fastenings and installations exposed to demanding industrial environments.
