Value Collection KP86174 Hex Nut 9/16-18 Grade 8 Pack 50

Product Description

The VALUE COLLECTION KP86174 is a 9/16-18 UNF hex nut manufactured from Grade 8 steel with a zinc yellow dichromate finish. Grade 8 is among the highest strength classifications for inch-series fasteners, making this nut suitable for high-load bolted assemblies where fastener integrity is critical. The zinc yellow dichromate coating provides corrosion resistance beyond standard zinc plating. The right-hand thread conforms to UNF standards. Each package contains 50 nuts. Licensed tradespeople and industrial maintenance techs working on structural, mechanical, or equipment assemblies will find this nut appropriate for demanding torque and load requirements.

This hex nut is used in applications requiring a fine-thread 9/16-18 UNF fastener with high tensile strength. Typical installation scenarios include heavy equipment, agricultural machinery, automotive frames, and structural mechanical assemblies where Grade 8 hardware is specified. The zinc yellow dichromate finish makes it identifiable at a glance on the job site and suitable for environments with moderate corrosion exposure. The 7/8-inch across-flats dimension accepts a standard 7/8-inch wrench or socket.

Key Features

Compatibility

Designed for use with 9/16-18 UNF Grade 8 bolts and threaded fasteners in any application calling for a fine-thread hex nut at this diameter and pitch.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with fastener grade requirements for the application. Always verify that the mating bolt is also rated Grade 8 or higher to maintain the integrity of the joint. Use a calibrated torque wrench and follow the torque specifications defined by the equipment manufacturer or applicable engineering standards for 9/16-18 UNF Grade 8 hardware. Inspect threads for damage or contamination before assembly.
