The VALUE COLLECTION NL5X00300-050BX is a hex lock nut with a nylon insert, manufactured from 18-8 A2 stainless steel with a bright uncoated finish. It uses an M3x0.5 thread size with a right-hand thread direction and meets DIN 985 standards. The nylon insert creates interference with mating threads to resist loosening caused by vibration and torque. This fastener is suited for maintenance, repair, and assembly work in industrial, HVAC, plumbing, and mechanical applications where corrosion resistance and secure locking are required. This package contains 50 nuts and is sold as a single package with a minimum order of 50 pieces.
This nut is appropriate for light-duty to medium-duty fastening applications involving M3 threaded fasteners. The 18-8 A2 stainless steel construction makes it a practical choice in environments where exposure to moisture, mild chemicals, or corrosion is a concern. Typical uses include equipment assembly, electrical enclosure hardware, and general mechanical fastening where a prevailing-torque lock nut is specified. Installers in HVAC, electrical, and plumbing trades frequently use this size for panel mounting, bracket attachment, and component securing tasks.
Designed as a DIN 985 nylon insert hex lock nut for use with M3x0.5 right-hand threaded fasteners in standard metric assemblies.
Installation is performed by hand and tool, typically with a standard metric wrench or nut driver sized for a 5.50 mm across-flats dimension. Nylon insert lock nuts are single-use by design and should not be reused after removal, as the nylon insert loses its locking effectiveness once deformed. No special tools or trade licensing are required, though installers should verify thread compatibility and torque requirements against the application specification before installation.
