Value Collection 39670 Hex Lock Nut 1-14 Grade 8 Steel

Product Description

The VALUE COLLECTION 39670 is a 1-14 UNF hex lock nut with a nylon insert locking style, manufactured from Grade 8 steel with a zinc yellow dichromate finish. The nylon insert compresses against the mating thread to resist loosening caused by vibration and torque cycling without damaging the fastener. At 1-3/64 inches in height and 1-7/16 inches across the flats, this nut fits standard 1-inch-diameter fine-thread fastener applications. It is a right-hand thread fastener and is sold individually with a minimum order quantity of 5 units. Installers in HVAC, plumbing, electrical, and general mechanical trades use this nut wherever a secure, reusable locking fastener is required on inch-series hardware.

This hex lock nut suits heavy-duty mechanical and structural fastening applications that demand vibration resistance. Grade 8 steel provides high tensile strength appropriate for demanding load-bearing connections. The zinc yellow dichromate finish delivers corrosion resistance suitable for indoor mechanical environments and light-duty exterior applications. Typical uses include equipment mounting, bracket fastening, and structural assembly in commercial and residential mechanical systems where fine-thread hardware is specified.

Key Features

• Nylon insert locking style resists vibration-induced loosening without marring mating threads
• Grade 8 steel construction provides high tensile strength for load-bearing applications
• Zinc yellow dichromate finish offers corrosion resistance in moderate environments
• 1-14 UNF right-hand thread for compatibility with inch-series fine-thread fasteners
• 1-7/16 inches across the flats fits standard hex wrenches and sockets

Compatibility

Designed for use with 1-inch diameter, 14 threads-per-inch UNF (Unified Fine) right-hand thread fasteners in inch-series applications.

Installation Notes

Installation requires a standard hex wrench or socket matching the 1-7/16-inch across-flats dimension. De-energize and isolate the equipment being serviced before working on any fastener connections in mechanical or electrical assemblies. The nylon insert is rated for one-time installation in critical applications; reuse on safety-critical joints is not recommended by general fastener practice. Follow applicable mechanical and structural codes for torque and joint requirements based on the specific application.
