Value Collection 47172 Flange Bolt 3/4-10 Unc Grade 8 10 Pack

Product Description

The VALUE COLLECTION 47172 is a smooth flange bolt designed for heavy-duty fastening applications requiring a wide bearing surface without a separate washer. Sized at 3/4-10 UNC with a 2-1/4 inch length under head and 1-3/4 inch thread length, this partially threaded bolt distributes clamping load across a 1-19/32 inch (1.5938 inch) integral smooth flange. Manufactured from Grade 8 alloy steel and finished with yellow zinc plating, it meets SAE J429 standards for mechanical and material properties. The hex drive allows standard wrench or socket installation. Sold in a package of 10.

This bolt is suited for structural and mechanical assemblies in industrial, commercial, and trade environments where high tensile strength and corrosion resistance are required. The smooth flange face is appropriate for applications where a serrated flange might damage a mating surface or where a clean bearing interface is specified. Typical uses include mounting brackets, equipment frames, and mechanical subassemblies across HVAC, electrical, plumbing, and general trade work. The yellow zinc coating provides moderate corrosion protection suitable for interior and sheltered exterior installations.

Key Features

• 3/4-10 UNC thread with 1-3/4 inch threaded length for strong, reliable engagement
• Integral smooth flange at 1-19/32 inch diameter eliminates need for a separate flat washer
• Grade 8 alloy steel construction for high tensile and proof load performance
• Yellow zinc plating meets SAE J429 finish requirements and provides corrosion resistance
• Hex drive compatible with standard sockets and wrenches
• Partially threaded shank allows shear load transfer in the unthreaded grip zone

Compatibility

Designed as a standard 3/4-10 UNC smooth flange bolt suitable for use in any application specifying a Grade 8 SAE J429 partially threaded hex flange fastener in inch measurements.

Installation Notes

Installation should be performed by a qualified mechanic or trade professional familiar with fastener torque specifications for Grade 8 hardware at the 3/4-10 thread size. Always consult the equipment manufacturer's torque table or a standard fastener reference before final tightening. Inspect mating threads and bearing surfaces for damage or contamination before assembly. Do not reuse fasteners that show signs of thread deformation, corrosion, or yield stretching.
