Value Collection C39056 Flange Bolt 3/4-10 Unc 3in Grade 8

Product Description

The VALUE COLLECTION C39056 is a smooth flange bolt designed for heavy-duty fastening applications requiring a built-in load-distributing flange. Sized at 3/4-10 UNC with a 3-inch length under the head, this bolt is partially threaded with 1-3/4 inches of thread engagement. The smooth flange measures 1-19/32 inches (1.5938 inches) in diameter, spreading clamp load across a wider bearing surface without the need for a separate washer. Manufactured from Grade 8 alloy steel and left uncoated, it meets IFI 111 and SAE J429 standards. A hex drive makes installation straightforward with standard tooling. Ideal for structural and mechanical assemblies where high tensile strength is required.

This flange bolt is suited for industrial, automotive, and mechanical maintenance applications where a Grade 8 fastener is specified. The partially threaded shank allows it to seat accurately in clearance holes while the smooth flange prevents surface damage to mating components. Typical applications include equipment frames, brackets, and structural assemblies that demand a high-strength, washer-faced bolted joint. Tradespeople in HVAC, mechanical, and general industrial service will find this bolt appropriate for field repairs and equipment assembly where IFI 111 and SAE J429 compliance is required.

Compatibility

Designed as a standard-dimension 3/4-10 UNC smooth flange bolt compatible with any application specifying a Grade 8 partially threaded hex flange bolt per IFI 111 and SAE J429.

Installation Notes

Installation should be performed by a qualified technician familiar with torque specifications for Grade 8 fasteners at 3/4-10 UNC. Always consult the equipment manufacturer's torque table before final tightening. Ensure mating threads are clean and free of debris before installation. Do not mix with lower-grade fasteners in the same joint assembly.
