Value Collection R63081449 Heavy Hex Nut 1-8 Unc

Product Description

The VALUE COLLECTION R63081449 is a heavy hex nut threaded to a 1-8 UNC specification with a right-hand thread direction. Manufactured from stainless steel, this nut is built for applications that demand corrosion resistance and structural integrity. The heavy hex profile provides a larger bearing surface and greater wall thickness compared to standard hex nuts, making it well-suited for high-load fastening work. It measures 1-5/8 inches across flats and 63/64 inches in height. The finish is uncoated, leaving the stainless steel in its natural state. Licensed tradespeople working in mechanical, structural, or piping assemblies will find this nut a reliable fastener for demanding service conditions.

This heavy hex nut is appropriate for use in commercial and industrial fastening applications where a 1-8 UNC thread engagement is required. The right-hand thread direction is the standard configuration for the majority of bolting assemblies. Stainless steel construction makes it a practical choice for environments with exposure to moisture, chemicals, or temperature cycling. It is sold individually and is suited for both new construction and maintenance or repair work on existing assemblies.

Key Features

• 1-8 UNC right-hand thread for compatibility with standard coarse-thread bolting systems
• Heavy hex profile with 1-5/8 inch across-flats dimension for increased bearing surface and wrench engagement
• Stainless steel construction provides corrosion resistance without additional coating
• 63/64 inch height suits high-load, thick-flange fastening applications
• Uncoated finish maintains dimensional tolerances and supports use with stainless hardware

Compatibility

Designed as a replacement or maintenance fastener for assemblies requiring a 1-8 UNC heavy hex nut with right-hand thread in stainless steel.

Installation Notes

Heavy hex nuts in this size range are typically installed by mechanical, structural, or pipefitting tradespeople using appropriately rated hand or torque wrenches. Always de-energize, depressurize, or isolate the assembly before servicing any fastener on an active system. Use a calibrated torque wrench and refer to the applicable engineering specification or code for the required fastening torque. Avoid mixing stainless steel fasteners with carbon steel components to prevent galvanic corrosion in wet environments.
