Value Collection 1-N-43C Hex Lock Nut 7/16-14 Stainless Steel

Product Description

The VALUE COLLECTION 1-N-43C is a 7/16-14 UNC hex lock nut with a nylon insert locking mechanism, manufactured from 18-8 stainless steel. The nylon insert creates interference with the mating thread to resist loosening under vibration and torque, making this nut well suited for mechanical assemblies where maintaining clamp load is critical. At 0.023 pounds per unit, it is a lightweight fastener used across a wide range of trade and industrial applications. Licensed tradespeople and maintenance technicians specify this style when a prevailing-torque lock nut is required without the use of adhesives or chemical threadlockers.

This hex lock nut is appropriate for use in HVAC equipment assemblies, plumbing brackets, electrical enclosures, pool equipment frames, and general mechanical installations where stainless steel corrosion resistance is required. The 18-8 stainless steel grade offers good resistance to rust and oxidation, making it a practical choice for both indoor and outdoor or wet-environment fastening. Right-hand thread direction follows standard UNC practice. This nut is sold individually but carries a minimum order quantity of 25 units.

Key Features

• 7/16-14 UNC right-hand thread for compatibility with standard inch-series fastener systems
• Nylon insert locking style provides prevailing-torque resistance against vibration-induced loosening
• 18-8 stainless steel construction resists corrosion and oxidation in wet or outdoor environments
• Height of 29/64 inches and 5/8 inches width across flats fits standard hex wrench and socket tooling
• Lightweight at 0.023 pounds per nut, minimizing added weight in assemblies

Compatibility

Designed as a standard UNC inch-series prevailing-torque lock nut for use with any 7/16-14 threaded bolt or stud in mechanical, HVAC, plumbing, or electrical applications requiring an 18-8 stainless steel fastener.

Installation Notes

Installation is performed by hand-threading the nut onto a clean, undamaged 7/16-14 bolt or stud, then tightening with a standard 5/8-inch hex wrench or socket driver. Always inspect mating threads for damage or contamination before installation. Because the nylon insert is a single-use locking feature, the nut should not be reused after removal from service. Follow applicable equipment manufacturer torque guidelines and relevant mechanical codes when specifying fastener clamp load.
