Value Collection 822412MSC Flange Bolt 3/4-16 Unf 1-3/4 in Grade 8

Product Description

The VALUE COLLECTION 822412MSC is a smooth flange bolt designed for high-strength fastening applications in mechanical, industrial, and trade assembly work. This bolt features a 3/4-16 UNF thread, a fully threaded shank measuring 1-3/4 inches under the head, and a smooth flange with a 1-19/32 inch diameter. Constructed from Grade 8 alloy steel with a phosphate and oil finish, it delivers the tensile strength and corrosion resistance demanded in demanding fastener applications. The hex drive allows standard wrench or socket installation. It meets IFI 111 and SAE J429 standards, making it suitable for structural and mechanical assemblies where rated fasteners are required.

This bolt is used in mechanical assemblies, heavy equipment maintenance, automotive applications, and general industrial fabrication where a flanged bearing surface is needed to distribute clamping load without a separate washer. The smooth flange profile seats flush against mating surfaces, reducing stress concentration. Trades including millwrights, diesel mechanics, and industrial maintenance technicians commonly use Grade 8 UNF flange bolts in high-vibration environments where fine-thread engagement and rated strength are critical.

Key Features

• 3/4-16 UNF fully threaded shank — fine-thread engagement for high-vibration resistance
• 1-3/4 inch length under head — thread length matches full shank length
• Grade 8 alloy steel construction — high tensile strength rated fastener
• Smooth flange diameter of 1-19/32 inches — distributes load without a separate washer
• Phosphate and oil finish — provides corrosion inhibition and lubricity during installation
• Meets IFI 111 and SAE J429 standards — verified for structural and mechanical use

Compatibility

Designed as a standard-dimension UNF smooth flange bolt suitable for mechanical assemblies, heavy equipment, and industrial applications requiring a Grade 8 rated fastener with a 3/4-16 fine thread pattern.

Installation Notes

Installation should be performed by a qualified mechanic or trades professional familiar with rated fastener torque specifications for Grade 8 hardware. Ensure mating threads are clean and free of debris before installation. Apply appropriate thread lubricant if torque values are based on lubricated conditions. Follow applicable industry standards and equipment manufacturer specifications for final torque values — do not use torque values from any source not specific to the application.
