Value Collection B52001648 Hex Nut 2-12 Grade 8 Steel

Product Description

The VALUE COLLECTION B52001648 is a heavy-duty hex nut threaded to a 2-12 UN specification in right-hand orientation. Manufactured from Grade 8 steel with a bright, uncoated finish, this nut is built for high-strength bolted assemblies where tensile and proof load requirements are demanding. It measures 3.125 inches across the flats and 1.719 inches in height, making it suitable for large-diameter fastener applications in industrial, construction, and mechanical installations. Licensed tradespeople and maintenance mechanics working on heavy equipment, structural connections, and machinery rely on this grade for its elevated yield strength compared to lower-grade fasteners.

This hex nut is used in applications where a 2-12 UN thread engagement is required, typically in heavy industrial fabrication, structural steel assembly, agricultural equipment, and heavy-duty machinery maintenance. Its Grade 8 rating makes it appropriate for high-load bolted joints where standard-grade hardware would not meet tensile requirements. The uncoated finish is suited for environments where a secondary coating or thread lubricant will be applied by the installer, or where raw steel is acceptable for the service condition.

Key Features

• Grade 8 steel construction for high-strength, high-load bolted connections
• 2-12 UN right-hand thread standard for compatibility with matching fasteners
• 3.125 inches across flats for use with standard heavy-duty wrenching tools
• 1.719 inches height provides full thread engagement on large-diameter bolts
• Bright, uncoated finish allows for field-applied coatings or lubricants as needed
• Does not meet military specifications — intended for commercial and industrial use

Compatibility

Designed for use with 2-12 UN threaded fasteners requiring a Grade 8 steel hex nut. Verify thread pitch, diameter, and torque specification against the bolted assembly requirements before installation.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with high-strength fastener torque requirements for the specific application. Always verify that the mating bolt is also rated Grade 8 or higher before assembling a high-load joint. Use calibrated torque tooling and follow applicable structural or equipment manufacturer torque specifications. Inspect threads for damage or contamination before assembly to ensure full load-bearing engagement.
