Value Collection R56001364 Heavy Hex Nut 3/4-10 Unc

Product Description

The VALUE COLLECTION R56001364 is a heavy hex nut designed for 3/4-10 UNC threaded fastener applications. Manufactured from stainless steel with a right-hand thread direction, this nut meets the dimensional requirements of the heavy hex standard, featuring a 1-1/4 inch across-flats width and a height of approximately 47/64 inches. The uncoated finish makes it well suited for environments where corrosion resistance of the base material is the primary requirement. This nut is installed by maintenance technicians, pipefitters, millwrights, and general tradespeople working on structural, mechanical, and industrial fastener assemblies.

Heavy hex nuts are commonly used in structural steel connections, pipe flanges, heavy equipment assemblies, and industrial machinery where a larger bearing surface is required compared to a standard hex nut. The stainless steel construction makes this nut appropriate for outdoor, wet, or corrosive environments. Right-hand thread engagement is standard for the vast majority of mechanical assemblies, making this a direct-fit replacement or new-installation fastener in a wide range of applications.

Key Features

• 3/4-10 UNC thread size for compatibility with standard coarse-thread fastener assemblies
• Heavy hex geometry with 1-1/4 inch across-flats width provides increased bearing surface and wrench engagement
• Stainless steel construction offers inherent corrosion resistance without surface coatings
• Right-hand thread direction conforms to standard mechanical assembly practice
• Uncoated finish — no risk of coating delamination in high-load or high-vibration environments
• Does not meet military specifications — intended for commercial and industrial use

Compatibility

Designed for use with 3/4-10 UNC threaded bolts, studs, and rods in commercial and industrial fastener applications requiring a heavy hex nut profile.

Installation Notes

Installation is performed by hand-threading the nut onto a compatible 3/4-10 UNC fastener, then torquing to the value specified by the joint design or applicable structural standard. Ensure mating threads are clean and free of debris before assembly. Use a properly sized wrench or impact socket rated for 1-1/4 inch across-flats engagement. Stainless steel fasteners are susceptible to galling — apply an appropriate anti-seize compound when conditions warrant.
