Value Collection 822323MSC Flange Bolt 3/4-10 Unc Grade 8

Product Description

The VALUE COLLECTION 822323MSC is a smooth flange bolt designed for high-strength fastening applications in mechanical, industrial, and trade assembly work. It features a 3/4-10 UNC thread form with a 1-3/4 inch thread length on a 2-1/4 inch length under head, partially threaded shank. Manufactured from Grade 8 alloy steel with a phosphate and oil finish, this bolt delivers elevated tensile strength and corrosion resistance suitable for demanding service conditions. The integrated smooth flange distributes clamping load across a wider bearing surface, eliminating the need for a separate washer in many installations. It meets SAE J429 standards. Installed by millwrights, pipefitters, and general mechanical contractors where high-clamp-load hex bolts are specified.

This flange bolt is suited for structural and mechanical assembly applications where a smooth, non-serrated flange face is required. The partially threaded shank provides a clean grip zone that resists shear loading in precision-fit holes. Typical applications include heavy equipment assembly, structural steel connections, and general industrial machinery where SAE J429 Grade 8 fasteners are called out by engineering specifications. Sold individually, it fits standard 3/4-10 UNC tapped holes.

Key Features

• 3/4-10 UNC thread form meets SAE J429 Grade 8 tensile requirements
• Partially threaded shank with 1-3/4 inch thread length provides a clean shear zone
• Smooth flange diameter of 1-19/32 inches spreads clamping load without a separate washer
• Phosphate and oil finish provides baseline corrosion and wear resistance
• Grade 8 alloy steel construction for high-strength fastening duty
• Hex drive head compatible with standard 3/4-inch drive tooling

Compatibility

Designed as a standard SAE J429 Grade 8 smooth flange bolt for use in any application specifying a 3/4-10 UNC partially threaded hex flange bolt with a 2-1/4 inch length under head.

Installation Notes

Install using a calibrated torque wrench sized for 3/4-inch hex fasteners and follow the torque values specified in the applicable engineering drawing or fastener standard for Grade 8 bolts at this diameter. Ensure mating threads are clean and free of debris before installation. Verify that the flange seating surface is flat and free of burrs to achieve proper clamping load. Consult applicable codes and equipment manufacturer specifications before final torque.
