Value Collection MP39611 Hex Nut 1/4-28 Grade 8 Steel

Product Description

The VALUE COLLECTION MP39611 is a 1/4-28 UNF hex nut manufactured from Grade 8 steel with a zinc yellow dichromate finish. Grade 8 steel provides high tensile strength suited for demanding fastening applications where standard hardware-grade nuts are insufficient. The zinc yellow dichromate coating adds corrosion resistance and is a widely recognized indicator of the Grade 8 specification. This nut features a right-hand thread and measures 7/16 inches across the flats with a height of 7/32 inches. It is a standard mechanical fastener installed by electricians, HVAC technicians, plumbers, and general trade professionals across a broad range of equipment and structural applications.

This hex nut is used in residential and commercial trade applications wherever a 1/4-28 UNF fine-thread fastener is required. Fine-thread fasteners offer greater resistance to loosening under vibration, making this nut well suited for equipment panels, motor mounts, brackets, and mechanical assemblies common in HVAC, plumbing, and electrical trade work. It is sold individually with a minimum order quantity of 50 pieces.

Key Features

• Grade 8 steel construction for high tensile strength and load capacity
• Zinc yellow dichromate finish provides corrosion resistance and meets Grade 8 identification standard
• 1/4-28 UNF fine-thread specification resists loosening under vibration
• Right-hand thread for standard installation with common tools
• 7/16 inches across flats for use with standard 7/16-inch wrenches and sockets

Compatibility

Designed as a standard 1/4-28 UNF Grade 8 hex nut compatible with any 1/4-28 fine-thread fastener application requiring Grade 8 steel strength and a zinc yellow dichromate finish.

Installation Notes

Install with a 7/16-inch wrench or socket driver. Power down or de-energize any equipment before replacing fasteners on electrical enclosures or mechanical assemblies. Do not mix thread standards — confirm the mating bolt is also 1/4-28 UNF before installation. Follow applicable torque guidelines for Grade 8 fasteners as specified by the equipment manufacturer or governing mechanical codes.
