Value Collection C713023 Hex Nut 1-1/4-12 Grade 8 Steel

Product Description

The VALUE COLLECTION C713023 is a Grade 8 steel hex nut with a 1-1/4-12 UNF thread size, designed for high-strength fastening applications in industrial, mechanical, and trade service environments. The uncoated bright finish indicates this nut has not been plated or treated, making it suitable for applications where corrosion resistance is not a primary requirement but tensile strength and hardness are critical. Grade 8 classification means this fastener meets the mechanical property requirements for high-load bolted assemblies. It features a right-hand thread direction and is compatible with corresponding UNF bolts and studs of the same thread specification.

This hex nut is used in heavy-duty mechanical assemblies where fine-thread engagement and high clamping force are required. Typical applications include industrial equipment mounting, structural bolting, and machinery maintenance. The fine UNF thread pitch provides greater thread engagement per inch compared to coarse thread fasteners, which is advantageous in applications requiring precise torque control or resistance to vibration loosening. Machinists, millwrights, equipment technicians, and trade professionals working on mechanical systems routinely use Grade 8 fasteners of this size in demanding service conditions.

Key Features

• Grade 8 steel construction for high tensile strength and hardness in demanding assemblies
• 1-1/4-12 UNF fine thread for precise engagement and vibration resistance
• Right-hand thread direction, standard for most mechanical applications
• 1-7/8 inches across flats for use with standard hex wrench or socket tooling
• 1-1/16 inches height providing full thread engagement depth
• Bright uncoated finish with no additional plating or surface treatment

Compatibility

Designed for use with 1-1/4-12 UNF Grade 8 bolts and threaded studs requiring a standard hex nut. Verify thread class and grade requirements before installation to ensure proper fitment and load rating for the assembly.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with high-strength fastener assemblies. Ensure the mating bolt or stud is also Grade 8 or higher and shares the same 1-1/4-12 UNF thread specification before assembly. Always clean threads and inspect for damage prior to installation. Do not mix thread standards or grades, as mismatched fasteners can result in joint failure under load.
