Value Collection 47174 Flange Bolt 3/4-10 Unc 3in Grade 8

Product Description

The VALUE COLLECTION 47174 is a smooth flange bolt designed for high-strength fastening applications in structural, mechanical, and heavy equipment assemblies. It features a 3/4-10 UNC thread specification with a 3-inch length under head and partial threading at 1-3/4 inches of thread engagement. The integrated smooth flange measures 1-19/32 inches (1.5938 inches) in diameter, distributing clamp load over a wider bearing surface without requiring a separate washer. Manufactured from Grade 8 alloy steel to SAE J429 standards and finished with yellow zinc plating for corrosion resistance, this bolt is suited for demanding service environments where high tensile strength and reliable seating are required.

This flange bolt is appropriate for use in automotive, heavy equipment, agricultural machinery, and general industrial assembly where a hex-drive, partially threaded fastener with a built-in flange is specified. The partial thread design allows the unthreaded shank to bear shear loads cleanly while the threaded section provides secure clamping. Sold in a package of 10 units, this bolt suits MRO restocking and production line use. Installation is performed using standard hex tooling sized for 3/4-inch drive fasteners.

Key Features

• 3/4-10 UNC thread size with 1-3/4 inches of partial threading for shear-load-capable shank
• 3-inch length under head measured to SAE J429 standards
• Smooth integral flange at 1-19/32 inches diameter eliminates need for a separate flat washer
• Grade 8 alloy steel construction for high tensile and proof load requirements
• Yellow zinc plating provides baseline corrosion protection in moderate service environments
• Hex drive for use with standard wrenches and impact tooling

Compatibility

Designed as an OEM-style replacement or production-use fastener for applications specifying a 3/4-10 UNC smooth flange bolt with Grade 8 alloy steel and SAE J429 certification.

Installation Notes

Installation is performed by licensed mechanics, millwrights, or qualified maintenance technicians using hex wrenches or impact drivers rated for 3/4-inch fasteners. Always verify thread engagement depth and mating material compatibility before final torque. Do not mix Grade 8 fasteners with lower-grade nuts or tapped holes that are not rated for the corresponding clamp load. Inspect the flange seating surface for burrs or debris before installation to ensure full and even bearing contact.
