Value Collection C39061 Flange Bolt 1/2-20 Unf 2in Grade 8

Product Description

The VALUE COLLECTION C39061 is a smooth flange bolt designed for high-strength fastening applications where a wide bearing surface is needed without a separate washer. Sized at 1/2-20 UNF with a 2-inch length under head and 1-1/4 inch thread length, this partially threaded bolt is manufactured from Grade 8 alloy steel, making it suitable for high-load, high-torque joints. The integrated smooth flange measures 1-5/64 inches (1.0781 inches) in diameter, distributing clamping load evenly across the mating surface. It ships uncoated and meets IFI 111 and SAE J429 standards. Installers in mechanical, industrial, and trade applications will find this bolt appropriate wherever a flanged hex fastener is called for.

This flange bolt is used in a wide range of mechanical and structural assemblies including HVAC equipment frames, pump and compressor mounting, and general industrial fabrication. The smooth flange face is suited for applications where a serrated flange would damage the mating surface or where a clean bearing surface is required. Sold in a package quantity of 10, it is appropriate for shop stock or job-specific fastener kits.

Key Features

• Grade 8 alloy steel construction for high tensile and shear strength
• 1/2-20 UNF thread for fine-pitch engagement and vibration resistance
• Smooth flange eliminates need for a separate flat washer
• Partially threaded shank allows precise clamping without thread engagement through the full grip length
• Meets IFI 111 and SAE J429 fastener standards
• Uncoated finish suitable for use with thread-locking compounds or surface treatments applied in the field

Compatibility

Designed as a standard 1/2-20 UNF smooth flange hex bolt for use in any application requiring an IFI 111 and SAE J429 compliant Grade 8 partially threaded flange fastener in the inch measurement system.

Installation Notes

Installation is performed with a standard hex wrench or socket driver sized for a 1/2-inch hex bolt. Confirm the mating thread is 1/2-20 UNF before installation. Torque to the value specified by the equipment manufacturer or applicable engineering standard for Grade 8 fasteners at this diameter and pitch. Ensure the flange face seats flush and clean against the mating surface to achieve proper clamping load.
