Gibraltar 74213935 Heavy Hex Nut 3/4-10 Unc Steel

Product Description

The GIBRALTAR 74213935 is a heavy hex nut threaded to 3/4-10 UNC specification with a right-hand thread direction. Manufactured from steel with a black oxide finish, this nut delivers greater wrench bearing surface and wall thickness than standard hex nuts, making it the preferred choice in structural, heavy industrial, and high-load bolted connections. At 1-1/8 inches across flats and 41/64 inches in height, the heavy series profile provides added mechanical advantage in applications where standard nuts would be undersized or underrated. Installers in mechanical, structural, and maintenance trades use this style of nut with corresponding heavy hex bolts and structural fasteners.

This heavy hex nut is suited for structural steel assembly, industrial equipment mounting, machinery installation, and maintenance applications where UNC-threaded fasteners are required. The black oxide finish provides a mild level of corrosion resistance and reduces galling during installation. It is used in both indoor and outdoor industrial environments where a heavy-duty threaded connection is specified. Sold individually, it fits applications requiring a single replacement or spot-use fastener.

Key Features

• 3/4-10 UNC thread form with right-hand thread direction
• Heavy hex profile at 1-1/8 inches across flats for increased wrench surface
• 41/64 inches height providing greater thread engagement than standard hex nuts
• Steel construction for high tensile load capacity
• Black oxide finish for mild corrosion resistance and reduced surface friction
• Sold as a single unit with no minimum order beyond one piece

Compatibility

Designed for use with 3/4-10 UNC right-hand threaded bolts, studs, and threaded rod in structural and heavy industrial applications requiring a heavy hex nut profile.

Installation Notes

Installation is performed by mechanical, structural, and maintenance trades using standard hand or power tools sized for a 1-1/8 inch hex drive. Verify that the mating fastener is also 3/4-10 UNC right-hand thread before assembly. Apply appropriate thread lubricant or anti-seize compound where specified by the application. Follow applicable torque specifications defined by the engineering or project specification documents for the assembly.
