Value Collection B52001612 Hex Lock Nut 1-14 Unf

Product Description

The VALUE COLLECTION B52001612 is a nylon insert hex lock nut designed to resist loosening under vibration and dynamic loading. It carries a 1-14 UNF right-hand thread specification and is manufactured from Grade B steel with a zinc-plated finish for corrosion resistance in standard service environments. The nylon insert creates friction against the mating fastener thread, maintaining clamp load without requiring a secondary locking element such as a washer or thread-locking compound. At 1-3/64 inches high and 1-7/16 inches across the flats, this is a full-height, inch-series lock nut suited for structural and mechanical assembly work across HVAC, plumbing, and general industrial applications.

This nut is used in residential and commercial mechanical assemblies where vibration or cyclic loading could cause a standard hex nut to back off over time. Typical installation scenarios include equipment mounting, pipe support hardware, fan and blower assemblies, structural bracketing, and any application calling for a 1-14 UNF inch-series fastener. It is installed by hand and driven with a standard hex wrench or socket. The zinc-plated finish makes it suitable for interior and protected exterior use where mild corrosion resistance is required.

Key Features

• Nylon insert locking style resists loosening from vibration without secondary hardware
• 1-14 UNF right-hand thread in the inch measurement system
• Grade B steel construction for reliable mechanical strength
• Zinc-plated finish provides mild corrosion protection
• Full-height hex profile at 1-3/64 inches — fits standard sockets and wrenches
• Conforms to UNF fastener standard

Compatibility

Designed as a standard replacement or stock fastener for any assembly requiring a 1-14 UNF nylon insert hex lock nut in Grade B steel with a zinc-plated finish.

Installation Notes

Installation is performed with a standard hex socket or open-end wrench sized to 1-7/16 inches across the flats. Ensure mating bolt or stud threads are clean and free of debris before engagement. The nylon insert is single-use by design — a nut that has been fully run down and removed should be replaced rather than reused, as the insert locking torque degrades after initial installation. Follow applicable mechanical codes and equipment manufacturer torque requirements for the assembly being serviced.
