Value Collection R52001107 Hex Nut 1-1/2-12 Grade 8

Product Description

The VALUE COLLECTION R52001107 is a heavy-duty hex nut designed for high-strength fastening applications in structural, mechanical, and industrial assemblies. Manufactured from SAE J995 Grade 8 steel with a zinc yellow dichromate finish, this nut meets ANSI/ASME B18.2.2 dimensional standards. It carries a thread size of 1-1/2-12 UNF right-hand thread, a width across flats of 2.25 inches, and a height of 1.2813 inches. Hardness is rated at 26-36 HRC, confirming suitability for high-load, high-torque bolted joints. Machinists, maintenance mechanics, and industrial assemblers commonly specify this nut in equipment overhaul, machine building, and structural fabrication work.

This hex nut is suited for heavy industrial and commercial applications where a fine-thread, large-diameter fastener is required. The 1-1/2-12 thread pitch provides finer thread engagement than coarse-thread equivalents, making it appropriate for applications requiring precise torque control or resistance to loosening under vibration. Typical use scenarios include press frames, hydraulic cylinder end caps, large shaft retention hardware, and heavy equipment chassis fastening. Right-hand thread orientation is standard for these assemblies.

Key Features

• SAE J995 Grade 8 steel construction rated at 26-36 HRC for high-strength bolted joints
• 1-1/2-12 right-hand UNF thread for fine-pitch engagement in heavy-load applications
• Zinc yellow dichromate finish provides corrosion resistance and identification as a Grade 8 fastener
• Width across flats of 2.25 inches and width across points of 2.598 inches for standard wrench and socket fit
• Meets ANSI/ASME B18.2.2 dimensional standards for consistent fit and interchangeability

Compatibility

Designed as an OEM-style replacement or stock hex nut for any assembly requiring a 1-1/2-12 UNF right-hand thread, Grade 8 steel nut conforming to ANSI/ASME B18.2.2.

Installation Notes

Installation is performed by qualified mechanics or industrial assemblers using an appropriately sized wrench or impact socket rated for the torque demands of the joint. Always confirm mating bolt grade and thread specification before assembly to ensure a matched fastener pair. Clean threads of debris and inspect for damage before torquing. Follow the equipment manufacturer or applicable industry standard for torque specifications, as this data is not included with the fastener.
