Value Collection 821704MSC Flange Bolt 3/8-16 Unc Grade 8

Product Description

The VALUE COLLECTION 821704MSC is a smooth flange bolt engineered for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 3/8-16 UNC thread with 1 inch of thread engagement, a hex drive head, and a smooth 13/16-inch flange diameter that distributes clamping load over a wider surface area without the need for a separate washer. Constructed from Grade 8 alloy steel with a phosphate and oil finish, this bolt meets SAE J429 standards for tensile strength and dimensional accuracy. Total length under head is 1-3/4 inches.

This flange bolt is suited for use in automotive, heavy equipment, and industrial machinery applications where vibration resistance and high clamp load are required. The smooth flange style is appropriate for mating surfaces that require clean load distribution without serration marks. The partially threaded shank provides a consistent grip length and is installed with a standard hex wrench or socket. This item is sold individually but carries a minimum order quantity of 100 units, making it appropriate for shop stock or fleet maintenance programs.

Key Features

• 3/8-16 UNC thread form with 1 inch of partial thread length for controlled grip
• Smooth flange diameter of 13/16 inches eliminates need for a separate flat washer
• Grade 8 alloy steel construction meets SAE J429 tensile and proof load requirements
• Phosphate and oil finish provides baseline corrosion resistance and lubricity during installation
• Hex drive head compatible with standard 9/16-inch sockets and wrenches
• 1-3/4 inch length under head suits medium-depth fastening applications

Compatibility

Designed as a standard 3/8-16 UNC smooth flange bolt for use in any application requiring a Grade 8 alloy steel fastener conforming to SAE J429 dimensional and strength standards.

Installation Notes

Installation is performed by mechanical technicians, millwrights, or maintenance personnel using a standard hex socket or open-end wrench. Always verify that the mating thread is clean and undamaged before installation. Apply thread lubricant or thread-locking compound as required by the assembly specification. Follow the assembly torque specification provided by the equipment manufacturer for 3/8-16 Grade 8 hardware.
