This 1/4-20 UNC x 3/4 inch length zinc-plated heavy hex lock nut features an expanding flex top for easy hand tightening without requiring additional tools. The flex top reduces the possibility of over-tightening, providing an anti-loosening function for bolted assemblies. Its high tensile strength and smooth texture provide security and durability even under severe conditions. This lock nut is suitable for securing fasteners in applications where vibration or torque may loosen standard nuts, ideal for the aerospace, automotive, or any high-vibration environments where maintenance is difficult or costly. With its compact design and self-locking feature, this lock nut helps reduce assembly time while increasing safety and reliability of fastened joints, making it an essential component in Flex-Loc systems.
