Value Collection C39026 Flange Bolt 3/8-16 Unc 1 in Grade 8

Product Description

The VALUE COLLECTION C39026 is a smooth flange bolt designed for high-strength fastening applications in mechanical, industrial, and trade assembly work. Sized at 3/8-16 UNC with a 1-inch length under head and fully threaded shank, this bolt distributes clamping load across a 13/16-inch (0.8125 inches) integral smooth flange, eliminating the need for a separate washer. Manufactured from Grade 8 alloy steel in an uncoated finish, it meets IFI 111 and SAE J429 standards. The hex drive allows installation with standard hand or power tools. This fastener is suited for applications where vibration resistance and high tensile strength are required.

This bolt is commonly used in HVAC equipment assembly, mechanical mounting, structural bracketing, and general industrial fabrication. The smooth flange style is appropriate where a clean bearing surface is needed against softer substrates or where marring must be minimized. Grade 8 alloy steel construction makes it appropriate for high-load joints in both stationary and light-vibration environments. Installers in HVAC, plumbing, electrical enclosure work, and general mechanical trades will find this a standard fastener for equipment mounting and frame assembly.

Key Features

• 3/8-16 UNC fully threaded shank provides maximum thread engagement over the full 1-inch length under head
• Integral smooth flange at 13/16 inches (0.8125 inches) diameter replaces a separate flat washer and distributes clamp load
• Grade 8 alloy steel construction meets SAE J429 and IFI 111 standards for high tensile and proof load requirements
• Hex drive compatible with standard 9/16-inch wrenches and sockets
• Uncoated finish suitable for dry indoor environments or applications where a coating is applied after assembly
• Minimum order quantity of 25 pieces supports jobsite and shop stocking needs

Compatibility

Designed as a standard 3/8-16 UNC smooth flange bolt for use in any application requiring an IFI 111 or SAE J429 compliant Grade 8 fastener with an integral flange bearing surface.

Installation Notes

Install with a 9/16-inch hex wrench or socket driver; ensure mating threads are clean and free of debris before assembly. Torque to the value specified in the equipment manufacturer's documentation for 3/8-16 Grade 8 fasteners — do not rely on generic values without verifying the joint design. De-energize or shut down any equipment before performing fastener service on live assemblies. Follow applicable mechanical and structural codes for the jurisdiction and application type.
