Abb H-116-D Square Nut 1/2-13 Steel

Product Description

The ABB H-116-D is a square nut with a 1/2-13 thread specification, manufactured from steel. Square nuts provide a larger bearing surface compared to standard hex nuts, making them well suited for use in channels, tracks, and applications where the nut must resist rotation during tightening. This fastener is a standard hardware component used across HVAC equipment assembly, electrical enclosures, plumbing bracket systems, and general mechanical installations. Licensed tradespeople and maintenance technicians stock this size for routine equipment assembly, repair, and field fabrication work.

The H-116-D fits applications requiring a 1/2-13 UNC thread fastener in a square-body profile. Common use cases include mounting hardware in unistrut or slotted channel systems, securing brackets and structural supports, and assembling equipment frames. The steel construction handles standard indoor mechanical environments where corrosion resistance is not a primary concern.

Key Features

• Square body profile provides increased bearing surface for improved load distribution
• 1/2-13 UNC thread for compatibility with standard 1/2-inch fastener systems
• Steel construction offers solid mechanical strength for structural and equipment applications
• Resists rotation in channel and track installations due to flat side geometry

Compatibility

Designed as a standard 1/2-13 UNC square nut for use with 1/2-inch threaded rod, bolts, and fastener assemblies in mechanical, HVAC, plumbing, and electrical support applications.

Installation Notes

Installation should be performed by a qualified tradesperson using appropriate wrenches or socket tools sized for the nut body. Ensure mating threads are clean and free of debris before assembly. Do not overtighten beyond the torque requirements of the connected assembly. Always de-energize and isolate equipment before performing fastener work on live electrical or mechanical systems.
