Value Collection 34270 Hex Lock Nut Nylon Insert Grade 2

Product Description

The VALUE COLLECTION 34270 is a hex lock nut with a nylon insert locking style, manufactured from Grade 2 steel with a zinc-plated finish. The nylon insert creates interference with the mating thread, resisting loosening caused by vibration and torque. The nut measures 15/64 inches in height and 11/32 inches across the flats, with a right-hand Unified National Coarse (UNC) thread direction. This is a standard inch-system fastener suited for general mechanical assembly work in HVAC, plumbing, electrical, and light industrial applications. Installers, technicians, and assemblers working with standard UNC threaded fasteners will find this nut compatible with common bolt and stud stock.

This hex lock nut is used in a wide range of light-duty mechanical assembly scenarios where vibration resistance is required without the use of adhesive thread-locking compounds. The compact profile and zinc coating make it suitable for both indoor and protected outdoor installations where mild corrosion resistance is acceptable. It is appropriate for residential and light commercial equipment panels, brackets, and structural fastening applications that call for an inch-system UNC fastener.

Key Features

• Nylon insert locking style resists loosening under vibration without adhesives
• Grade 2 steel construction provides adequate strength for general-purpose mechanical assembly
• Zinc-plated finish offers mild corrosion resistance for indoor and sheltered applications
• Right-hand UNC thread direction compatible with standard inch-system threaded fasteners
• Compact size: 15/64 inches high, 11/32 inches across the flats
• Inch measurement system; does not meet military fastener specifications

Compatibility

Designed as a general-purpose replacement or assembly fastener for standard UNC inch-system threaded bolts and studs used in light mechanical, HVAC, plumbing, and electrical equipment assembly.

Installation Notes

Hex lock nuts with nylon inserts are installed using standard hex wrenches or nut drivers sized to the across-flats dimension. Always ensure the mating bolt or stud thread specification matches the nut before installation. Nylon insert lock nuts are generally intended for single-use applications, as the locking torque of the nylon insert diminishes with each removal and reinstallation. Follow applicable equipment manufacturer guidelines and relevant codes when using fasteners in structural or safety-critical assemblies.
