Value Collection R52001300 Hex Nut 7/8-14 Grade 8

Product Description

The VALUE COLLECTION R52001300 is a 7/8-14 hex nut manufactured from SAE J995 Grade 8 steel with a zinc yellow dichromate finish. It is designed for high-strength fastening applications where corrosion resistance and load-bearing capacity are required. The right-hand thread pattern conforms to UN thread standards, and the fastener meets ANSI/ASME B18.2.2 dimensional requirements. At 1.3125 inches across flats and 0.75 inches in height, this nut is sized for use with 7/8-14 threaded fasteners in structural, mechanical, and industrial assemblies. Hardness is rated at 26-34 HRC, confirming its suitability for high-load connections.

This hex nut is suited for general industrial, mechanical, and structural fastening applications where a fine-thread, high-strength nut is specified. It is commonly used in machinery, equipment frames, and assemblies that require reliable clamping force and resistance to loosening under vibration. The zinc yellow dichromate finish provides a baseline level of corrosion protection for moderate-exposure environments. Maintenance technicians, machinists, and assembly workers in manufacturing and field service settings will find this nut appropriate for standard 7/8-14 bolt pairings.

Installation Notes

Installation should be performed by qualified mechanical or maintenance technicians using an appropriately sized wrench or socket matched to the 1-5/16 inch across-flats dimension. Disengage power, depressurize, or de-energize the assembly before servicing any fastened joint. Do not mix Grade 8 nuts with lower-grade fastener hardware in the same joint. Follow applicable industry or equipment manufacturer torque specifications based on thread size and application requirements.
