The Plastilocknut® nut is a black Nylon anti-vibration safety nut, reinforced with glass fibre. Due to its material, it is robust, electrically non-conductive and stainless. It is the perfect locking part to secure assemblies, even under high loads or pressures. It ensures optimal tightening with metal and/or plastic screws. The serration under the washer: – provides anti-unscrewing protection even in the presence of vibrations or shocks, – ensures optimum adhesion to the surfaces with which it is in contact. It can be unscrewed with a key and reused. Available from M5 to M12, Plastilocknut ® is a nut approaching DIN 6923.
