Value Collection 47173 Flange Bolt 3/4-10 X 2.5 in Grade 8

Product Description

The VALUE COLLECTION 47173 is a Grade 8 hex-drive flange bolt designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 3/4-10 UNC thread and a 2.5-inch length under the head, with an integrated flange that distributes clamping load across a wider bearing surface, reducing the need for a separate washer. The yellow zinc plating provides corrosion resistance in moderate-exposure environments. Compliance with SAE J429 confirms the bolt meets established mechanical and chemical property standards for Grade 8 fasteners. Sold in a package quantity of 10.

This bolt is suited for use in heavy-duty mechanical assemblies, agricultural equipment, commercial vehicle components, and general industrial fabrication where high tensile strength is required. The flange head design is particularly useful in applications where load spreading is important or where a washer face cannot be used due to space constraints or installation access. The inch-system thread sizing fits standard 3/4-10 tapped holes and nuts commonly found across North American equipment.

Key Features

• 3/4-10 UNC thread for compatibility with standard inch-system hardware
• 2.5-inch length under head provides substantial grip range for thick material stacks
• Grade 8 material rating meets SAE J429 mechanical property requirements for high-strength applications
• Integrated flange distributes clamp load without a separate flat washer
• Yellow zinc finish offers corrosion resistance in moderate service environments
• Sold in a 10-piece package, minimum order quantity of 1

Compatibility

Designed as a direct-fit replacement or stock fastener for any application requiring a 3/4-10 UNC hex flange bolt with a 2.5-inch length under head and Grade 8 strength rating.

Installation Notes

Installation is performed using a standard hex wrench or socket drive sized for a 3/4-inch bolt head. Verify thread engagement depth meets the fastener manufacturer and application requirements before torquing. Follow applicable torque specifications for Grade 8 fasteners from the equipment service manual or relevant fastener standards. Inspect the flange seating surface for debris or damage before assembly to ensure full bearing contact.
