SS Nylon Insert Lock Nut DIN985
Product Overview
SS Nylon Insert Lock Nut DIN985 is a widely used self-locking nut designed with a nylon collar that prevents the nut from loosening due to vibration or torque. Manufactured in accordance with the DIN985 standard, this fastener is especially favored in industries where secure and reliable threading is critical. The nylon insert deforms over mating threads, offering a tight and robust locking mechanism.
At Flybear Fastener, we produce premium-quality DIN985 stainless steel nylon lock nuts that deliver exceptional strength, corrosion resistance, and long-term reliability.
