The VALUE COLLECTION 34042 is a 3/4-16 hex lock nut with a nylon insert locking style, manufactured from Grade 2 steel with a zinc-plated finish. The nylon insert creates prevailing torque that resists loosening caused by vibration and dynamic loads without the need for additional thread-locking compounds. Measuring 13/32 inches in height with 1-1/16 inches across the flats, this nut follows UNF inch-series threading with a right-hand thread direction. It is suited for general mechanical assemblies where a reliable, reusable locking fastener is required across HVAC, plumbing, electrical, and industrial trade applications.
This hex lock nut is used in a wide range of light-duty to medium-duty fastening applications. The zinc-plated finish provides basic corrosion resistance suitable for interior and sheltered exterior environments. Trade professionals in HVAC, plumbing, electrical, and general mechanical work will find this nut appropriate for equipment panels, mounting brackets, pipe supports, and structural hardware assemblies where standard hex nuts lack adequate vibration resistance.
Designed as a general-purpose replacement or stock hex lock nut for any assembly using a 3/4-16 UNF inch-series threaded fastener where a nylon insert locking nut is specified.
Install using a standard open-end or combination wrench sized to 1-1/16 inches across the flats. Nylon insert lock nuts are rated for single use in critical applications; reuse is acceptable in non-critical assemblies but inspect the nylon insert for deformation before reinstalling. Ensure the mating bolt or stud is free of damage and debris before engagement. Follow applicable mechanical or electrical codes when torquing fasteners in regulated installations.
