The VALUE COLLECTION 34269 is a nylon insert hex lock nut designed to resist loosening caused by vibration and torque. Made from Grade 2 steel with a zinc-plated finish, this fastener provides reliable corrosion resistance in typical indoor and light-duty outdoor applications. It measures 3/16 inches in height with a 5/16-inch width across flats. The nylon insert creates a friction lock against the mating thread, eliminating the need for thread-locking compounds in most standard assembly situations. Suitable for use by HVAC technicians, plumbers, electricians, and mechanical contractors working with inch-based fastener systems.
This hex lock nut is used in general mechanical assemblies where vibration resistance is required. The UNC (Unified National Coarse) thread standard makes it compatible with the most common inch-based threaded fastener systems found in HVAC equipment panels, plumbing fixture brackets, electrical enclosures, and structural assemblies. The right-hand thread direction matches standard fastener tooling and installation practice. This part is sold individually but requires a minimum order quantity of 100 units per purchase.
Designed as an OEM-style replacement or general-use nylon insert hex lock nut for inch-based UNC threaded assemblies in HVAC, plumbing, electrical, and mechanical applications.
Installation is performed with a standard hex wrench or nut driver sized to 5/16 inches across flats. Ensure the mating bolt or stud is free of debris and damage before seating the nut. The nylon insert is single-use by design and should not be reused after removal, as the locking torque degrades with each installation cycle. Follow applicable mechanical and electrical codes when torquing fasteners in structural or load-bearing assemblies.
