Abb H-114-D Heavy Hex Nut 1/2-13 Steel

Product Description

The ABB H-114-D is a heavy hex nut with a 1/2-13 thread size, manufactured in steel. Heavy hex nuts are dimensionally larger across the flats and thicker than standard hex nuts, providing greater bearing surface and higher load capacity under torque. They are a staple fastener in structural, mechanical, and utility installations where standard hex nuts do not provide adequate clamping force. Tradespeople across HVAC, plumbing, electrical, and general mechanical work use heavy hex nuts wherever bolted connections require added strength and durability.

This fastener is suited for use in a wide range of trade and industrial applications. The 1/2-13 thread designation indicates a 1/2-inch nominal diameter with 13 threads per inch, which is a coarse unified national thread (UNC) specification. It is commonly used in structural bolting, equipment mounting, pipe support assemblies, and general mechanical connections in both residential and commercial settings.

Key Features

• Heavy hex profile provides larger bearing surface compared to standard hex nuts
• 1/2-13 UNC thread for compatibility with standard coarse-thread fastener systems
• Steel construction for strength and durability in demanding trade applications
• Suitable for structural and mechanical bolting across multiple trades

Compatibility

Designed as an OEM-style heavy hex nut for use with 1/2-13 UNC threaded bolts and studs in general mechanical and structural applications.

Installation Notes

Installation is performed by the applicable licensed trade or qualified installer depending on the application. Always ensure the mating bolt or stud matches the 1/2-13 thread specification before installation. Use appropriate hand tools or power tools rated for the fastener size, and follow applicable torque requirements specified by the equipment manufacturer or relevant codes such as AISC or ASME standards where applicable.
