Value Collection 34028 Hex Lock Nut 7/16-14 Nylon Insert

Product Description

The VALUE COLLECTION 34028 is a 7/16-14 UNC hex lock nut with a nylon insert locking mechanism, manufactured from Grade 2 steel with a zinc-plated finish. The nylon insert collar deforms around the mating thread when driven to torque, creating prevailing torque resistance that holds the nut in place under vibration and dynamic loading without requiring a secondary locking element. At 21/64 inches high with 11/16 inches across the flats, this is a standard-profile inch-series hex lock nut suited for general mechanical assembly work across a wide range of industrial and trade applications.

This nut is used in general-purpose bolted assemblies where vibration resistance is required. Typical applications include HVAC equipment mounting, sheet metal sub-frame fastening, electrical enclosure assembly, plumbing fixture hardware, and light structural connections. The right-hand thread direction and UNC thread form make it compatible with standard inch-series bolts and threaded rod. Grade 2 steel construction is appropriate for low-to-medium strength fastening requirements in non-critical assemblies. The zinc-plated finish provides a baseline level of corrosion resistance for indoor and sheltered-outdoor installations.

Key Features

• Nylon insert locking style provides reliable prevailing torque resistance without secondary hardware
• Grade 2 steel construction suited for general-purpose, non-critical assemblies
• Zinc-plated finish for corrosion resistance in indoor and light-duty outdoor environments
• Right-hand UNC thread direction — compatible with standard inch-series fasteners
• Compact profile: 21/64 inches high, 11/16 inches across flats

Compatibility

Designed as a standard inch-series hex lock nut for use with 7/16-14 UNC bolts and threaded rod in general mechanical and trade assembly applications.

Installation Notes

Installation is performed with a standard 11/16-inch open-end or combination wrench. Power down or de-energize any equipment before replacing fasteners on live assemblies. The nylon insert is single-use — once fully driven and removed, the locking torque is significantly reduced and the nut should be replaced rather than reused. Follow applicable torque guidelines for Grade 2 fasteners as specified by the equipment manufacturer or governing standards.
