Value Collection 822864MSC Flange Bolt 3/4-10 Unc 4 in Grade 8

Product Description

The VALUE COLLECTION 822864MSC is a partially threaded smooth flange bolt designed for heavy-duty fastening applications requiring a wide bearing surface and secure clamping force. This bolt features a 3/4-10 UNC thread size with a 1.75 inch thread length and a 4 inch length under head. The integrated smooth flange measures 1-19/32 inches (1.5938 inches) in diameter, distributing load across the joint face without a separate washer. Manufactured from Grade 8 alloy steel with a phosphate and oil finish, it delivers high tensile strength and corrosion resistance suitable for demanding mechanical assemblies.

This flange bolt is appropriate for structural, mechanical, and industrial fastening applications where Grade 8 alloy steel strength is specified. Typical install scenarios include heavy equipment, machinery frames, automotive components, and industrial mounting structures. The smooth flange face seats flush against mating surfaces, making it a practical choice for assemblies where a separate hardened washer would otherwise be required. The hex drive allows installation with standard hex wrenches or impact drivers common to mechanical and industrial trade work.

Key Features

• 3/4-10 UNC thread form for compatibility with standard inch-series tapped holes and nuts
• 4 inch length under head with 1.75 inch partial thread engagement length
• Integrated smooth flange at 1-19/32 inches diameter distributes clamping load without a separate washer
• Grade 8 alloy steel construction provides high tensile and proof load capacity
• Phosphate and oil finish offers moderate corrosion protection and lubricity during installation
• Meets IFI 111 and SAE J429 fastener standards

Compatibility

Designed as an OEM-style replacement or direct-use fastener for applications calling for a 3/4-10 UNC partially threaded smooth flange bolt in Grade 8 alloy steel per IFI 111 and SAE J429 standards.

Installation Notes

Installation is typically performed by mechanical or industrial tradespeople using a hex wrench, box wrench, or impact driver sized for the 3/4 inch hex drive. Verify tapped hole or nut thread class and condition before installation. Apply thread lubricant or anti-seize as required by the assembly specification; the phosphate and oil finish provides baseline lubricity but may not substitute for application-specific torque requirements. Always refer to the equipment manufacturer or applicable fastener standards for proper torque values before tightening.
