Value Collection KP26447 Hex Nut 1-3/8-12 Grade 8 2-pack

Product Description

The VALUE COLLECTION KP26447 is a Grade 8 steel hex nut threaded to a 1-3/8-12 UN right-hand thread specification. It carries a zinc yellow dichromate finish that provides corrosion resistance in demanding service environments. At 2-1/16 inches across the flats and a height of 1-11/64 inches, this nut is sized for heavy-duty fastening applications where high clamping force and hardness are required. Hardness is rated at 26-36 HRC, consistent with SAE J995 Grade 8 requirements. This package contains 2 nuts. Licensed tradespeople and maintenance technicians working on structural assemblies, heavy equipment, and industrial machinery rely on Grade 8 fasteners for critical joint integrity.

This hex nut is suited for high-load bolted connections in industrial, agricultural, construction, and heavy equipment applications. Its 1-3/8-12 thread pitch indicates a fine-thread configuration on a large-diameter fastener, making it appropriate for joints where precise clamping load control and resistance to vibration loosening are priorities. The zinc yellow dichromate finish provides a baseline level of corrosion protection suitable for indoor and controlled-environment installations. Machinists, millwrights, equipment technicians, and maintenance professionals typically use this class of fastener in structural and drivetrain assemblies.

Key Features

• SAE J995 Grade 8 steel construction with 26-36 HRC hardness rating for high-strength fastening
• 1-3/8-12 UN right-hand thread — fine-pitch configuration for vibration-resistant clamping
• Zinc yellow dichromate finish for baseline corrosion protection
• 2-1/16 inch width across flats conforms to ANSI ASME B18.2.2 dimensional standard
• Package quantity of 2 nuts per order unit

Compatibility

Designed as a standard hex nut for use with 1-3/8-12 UN threaded fasteners and bolts conforming to ANSI ASME B18.2.2 dimensional requirements in heavy-duty structural and mechanical assemblies.

Installation Notes

Installation should be performed by qualified mechanical tradespeople familiar with high-strength fastener torque requirements for the application. Always verify thread engagement and inspect mating bolt threads for damage or contamination before assembly. Do not mix Grade 8 nuts with lower-grade bolts or studs. Follow the applicable equipment manufacturer or structural specification for torque values — do not substitute general-purpose torque guidelines for engineered joint requirements.
