Abb H-114-A Heavy Hex Nut 1/4-20 Steel

Product Description

The ABB H-114-A is a heavy hex nut with a 1/4-20 thread size, manufactured from steel. Heavy hex nuts have a larger diameter and greater thickness than standard hex nuts, providing increased bearing surface and improved resistance to loosening under vibration or high-load conditions. This style of fastener is commonly used in structural, mechanical, and utility connections where extra clamping strength is required. HVAC, plumbing, and electrical contractors reach for heavy hex nuts when securing equipment frames, pipe supports, and panel components that see regular stress or movement.

The H-114-A suits general trade applications where a 1/4-20 threaded connection requires a more robust nut than a standard series fastener. Typical install scenarios include equipment mounting brackets, conduit support hardware, pipe hanger assemblies, and similar structural connections found in commercial and residential mechanical systems.

Key Features

• Heavy hex profile provides greater bearing surface than standard hex nuts
• 1/4-20 thread size fits widely available threaded rod, bolts, and hardware
• Steel construction delivers reliable strength for structural and mechanical connections
• Increased thickness resists loosening under vibration and dynamic loads

Compatibility

Designed as a standard 1/4-20 heavy hex nut suitable for use with any 1/4-20 threaded fastener in structural, mechanical, or utility applications.

Installation Notes

Heavy hex nuts are installed by licensed mechanical, electrical, or plumbing contractors as part of equipment mounting and support assemblies. De-energize or shut down any associated equipment before working on fastened connections. Use the appropriate wrench size for heavy hex profile to avoid rounding the flats. Torque to the specification called out in the equipment or structure manufacturer documentation.
