Value Collection C39048 Flange Bolt 5/8-11 Unc Grade 8

Product Description

The VALUE COLLECTION C39048 is a smooth flange bolt designed for high-strength fastening applications where a built-in bearing surface is required. It features a 5/8-11 UNC thread size with a 2-1/4 inch length under head and partial threading measuring 2-1/4 inches. The integrated smooth flange distributes clamping load across a wider surface area, reducing the need for a separate washer. Manufactured from Grade 8 alloy steel in an uncoated finish, this bolt meets IFI 111 and SAE J429 standards. It is installed using a hex drive and is suited for heavy-duty mechanical and structural assemblies.

This flange bolt is appropriate for use in industrial, mechanical, and trade-service applications requiring a high-strength UNC fastener. The smooth flange face is compatible with standard flange joint assemblies and is commonly used in equipment mounting, structural connections, and machinery maintenance. Its Grade 8 alloy steel construction makes it suitable for high-load environments encountered in HVAC equipment installation, fabrication, and general mechanical trade work. This part is sold individually with a minimum order quantity of 10 units.

Installation Notes

Installation should be performed by a qualified mechanic or trade professional using a calibrated torque wrench and the appropriate hex socket. De-energize and lock out all equipment before replacing structural fasteners. Consult the equipment manufacturer torque specifications for the assembly being serviced, as no torque value is specified for this fastener individually. Inspect mating surfaces and threads for damage before installation.
