Value Collection 306108BR Hex Nut 2-12 Grade 8

Product Description

The VALUE COLLECTION 306108BR is a heavy-duty hex nut designed for high-load fastening applications requiring superior tensile strength. Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this nut provides corrosion resistance while meeting the mechanical demands of structural and industrial assemblies. It carries a 2-12 thread size with a right-hand thread direction conforming to UN thread standards. The 3-1/8-inch width across flats and 1-23/32-inch height make it suitable for large-diameter bolted connections. Machinists, millwrights, and industrial maintenance technicians are the primary installers of this fastener.

This hex nut is suited for heavy industrial, construction, and mechanical assembly applications where Grade 8 strength is specified. It is commonly used in structural steel connections, heavy equipment fabrication, and high-tension bolted joints where standard-grade fasteners are not adequate. The zinc yellow dichromate finish provides a layer of corrosion protection appropriate for shop and controlled outdoor environments. This nut does not meet military specifications and is intended for commercial and industrial use.

Key Features

• Grade 8 steel construction delivers high tensile and proof load strength for demanding fastening applications
• Zinc yellow dichromate finish provides corrosion resistance and is visually distinctive for grade identification
• Right-hand thread direction conforms to UN thread standards for broad compatibility
• 3-1/8-inch width across flats accommodates standard heavy-duty wrenching tools
• 1-23/32-inch height provides substantial thread engagement for secure clamping force

Compatibility

Designed as an OEM-style replacement or direct-use hex nut for Grade 8 bolted assemblies with a 2-12 UN thread specification in industrial and structural applications.

Installation Notes

Installation should be performed by qualified machinists, millwrights, or maintenance technicians familiar with large-diameter fastener assemblies. Always degrease mating threads and inspect for damage before installation. Use a calibrated torque wrench appropriate for the fastener size and joint specification. Follow applicable structural or mechanical codes for torque and preload requirements for the specific assembly.
