Value Collection 822424MSC Flange Bolt 3/4-16 Unf 2-1/4 in Grade 8

Product Description

The Value Collection 822424MSC is a smooth flange bolt engineered for high-strength fastening applications requiring a stable clamping surface without a separate washer. It features a 3/4-16 UNF thread size, a partially threaded shank with 1.75 inches of thread length, and an overall length under head of 2.25 inches. Constructed from Grade 8 alloy steel with a phosphate and oil finish for corrosion resistance, this bolt meets IFI 111 and SAE J429 standards. The hex drive head makes installation straightforward with standard tools. Maintenance technicians, millwrights, and mechanical contractors install this type of fastener in structural and equipment assemblies across industrial and commercial settings.

This smooth flange bolt is suited for applications where the integrated flange distributes clamping load across a wider surface area, reducing the risk of fastener pull-through or surface damage. The 1.5938-inch flange diameter provides consistent load distribution on sheet metal, brackets, and structural components. It is appropriate for use in heavy equipment assembly, machinery mounting, automotive fabrication, and general mechanical construction where Grade 8 tensile strength is specified. The partially threaded shank allows for accurate shank-to-hole fits in clearance applications.

Key Features

• 3/4-16 UNF thread for fine-pitch engagement and vibration resistance
• Grade 8 alloy steel construction for high tensile strength fastening
• Smooth flange eliminates need for a separate flat washer
• 1.5938-inch flange diameter distributes clamping load evenly
• Phosphate and oil finish provides baseline corrosion protection
• Meets IFI 111 and SAE J429 fastener standards

Compatibility

Designed as an OEM-style replacement or direct-use fastener for assemblies specifying a 3/4-16 UNF partially threaded smooth flange bolt with a 2.25-inch length under head and Grade 8 alloy steel construction.

Installation Notes

Installation should be performed by a qualified mechanic or millwright familiar with high-strength fastener torque requirements per SAE J429 Grade 8 specifications. Always verify hole clearance and thread engagement depth before final tightening. Use a calibrated torque wrench and follow the assembly engineer's torque specification for the joint design. Do not reuse fasteners that show signs of thread damage, galling, or corrosion.
