Value Collection KP86168 Hex Nut 1-8 Unc Grade 8 25 Pack

Product Description

The VALUE COLLECTION KP86168 is a heavy-duty hex nut designed for high-load fastening applications where mechanical strength and corrosion resistance are required. Manufactured from Grade 8 steel, this nut meets the demands of structural and industrial assemblies subject to significant tensile and shear forces. The zinc yellow dichromate finish provides a corrosion-resistant barrier while serving as a visual identifier of the Grade 8 classification. The nut features a 1-8 UNC right-hand thread and measures 1.5 inches across the flats, with a height of 55/64 inch. It is sold in packages of 25 units.

This hex nut is suited for use in mechanical, structural, and industrial assembly work where Grade 8 fasteners are specified. Common applications include equipment mounting, structural steel connections, machinery assembly, and any bolted joint requiring high preload and reliable clamp force. The 1-8 UNC thread size is a coarse-thread designation widely used in heavy-duty industrial and commercial construction settings. Licensed trades professionals including millwrights, ironworkers, plumbers, and HVAC mechanics regularly work with Grade 8 fasteners in equipment installation and structural support work.

Key Features

• Grade 8 steel construction for high tensile strength in demanding fastening applications
• Zinc yellow dichromate finish provides corrosion resistance and identifies Grade 8 classification
• 1-8 UNC right-hand thread for compatibility with standard coarse-thread bolt systems
• 1.5 inches across flats for use with standard 1-1/2 inch wrenches and sockets
• Height of 55/64 inch provides full thread engagement depth
• Sold in a 25-piece package for job-site and shop stock convenience

Compatibility

Designed for use with 1-8 UNC Grade 8 hex bolts and threaded rod following standard UNC coarse-thread specifications. Right-hand thread direction is the standard for general fastening applications.

Installation Notes

Installation should follow applicable torque specifications for Grade 8 fasteners as outlined in the relevant design or engineering standard for the assembly. Always ensure the mating bolt is also Grade 8 or higher to maintain the integrity of the joint. Use a properly sized 1-1/2 inch wrench or socket to avoid rounding the flats. Do not mix Grade 8 fasteners with lower-grade components in structural or high-load connections.
