Value Collection 99797 Hex Nut 3/8-24 Grade 8 Steel Black Oxide

Product Description

The VALUE COLLECTION 99797 is a 3/8-24 UNF hex nut manufactured from Grade 8 steel with a black oxide finish. It features a right-hand thread and measures 9/16 inches across the flats with a height of 21/64 inches. Grade 8 steel provides high tensile strength suited for demanding fastening applications where standard-grade hardware is not adequate. The black oxide finish offers mild corrosion resistance and reduces light reflection. This nut is installed by mechanics, millwrights, maintenance technicians, and general tradespeople working with fine-threaded fastener assemblies requiring a high-strength nut.

This hex nut is suited for use in mechanical assemblies, equipment mounting, structural connections, and general industrial or trade applications where a 3/8-24 UNF fine-thread specification is required. The fine thread pitch of the 3/8-24 UNF standard provides greater thread engagement and improved resistance to loosening under vibration compared to coarse-thread equivalents, making it a practical choice for high-load or vibration-prone installations.

Key Features

• Grade 8 steel construction for high tensile strength
• Black oxide finish for mild corrosion resistance and reduced reflectivity
• 3/8-24 UNF fine right-hand thread
• 9/16 inches across flats for standard wrench compatibility
• 21/64 inches height for standard hex nut profile

Compatibility

Designed for use with 3/8-24 UNF fine-thread bolts and studs in applications requiring a Grade 8 steel hex nut with a right-hand thread direction.

Installation Notes

Install with a standard 9/16-inch wrench or socket. Ensure mating bolt or stud threads are clean and undamaged before assembly. Verify the mating fastener is also rated Grade 8 or higher to maintain the integrity of a high-strength joint. Follow applicable fastener standards and torque specifications provided by the equipment manufacturer for the specific application.
