Value Collection 825168MSC Serrated Flange Bolt 5/8-11 Unc

Product Description

The VALUE COLLECTION 825168MSC is a fully threaded serrated flange bolt designed for secure, vibration-resistant fastening in industrial and mechanical assemblies. It features a 5/8-11 UNC thread with a 2-inch length under head and a 1.33-inch serrated flange that bites into the mating surface to prevent loosening under load. The hex drive allows installation with standard hex wrenches or sockets. Manufactured from Grade 5 steel with a zinc-plated finish, this bolt meets ASME B18.6.3 and SAE J429 standards. It is suited for maintenance, fabrication, and OEM assembly work where a reliable, corrosion-resistant fastener is required.

This serrated flange bolt is used across a wide range of industrial, HVAC, plumbing, and mechanical applications where a built-in flange eliminates the need for a separate flat washer and the serrations provide added resistance to loosening caused by vibration. Typical applications include equipment frames, brackets, and structural assemblies in both commercial and light industrial settings. The fully threaded shank provides maximum thread engagement across the full 2-inch bolt length, making it well suited for thin-material clamping situations.

Key Features

• 5/8-11 UNC thread with 2-inch length under head for versatile fastening depth
• Fully threaded shank maximizes thread engagement across the entire length
• Serrated flange bites into the work surface to resist vibration-induced loosening
• 1.33-inch flange diameter distributes clamping load without a separate washer
• Grade 5 steel construction meets SAE J429 mechanical requirements
• Zinc-plated finish provides corrosion resistance in general service environments

Compatibility

Designed as a standard 5/8-11 UNC serrated flange bolt suitable for use in any application requiring ASME B18.6.3 and SAE J429 compliant Grade 5 hex flange fasteners.

Installation Notes

Installation is typically performed by mechanical technicians, millwrights, or field service personnel using a standard hex wrench or socket driver. Always ensure mating threads are clean and free of debris before installation. Do not exceed torque values appropriate for Grade 5 fasteners of this thread size as specified by the relevant fastener standard or equipment manufacturer. The serrated flange is designed for use against metal or similarly hard surfaces and should not be used against soft materials that may be damaged by the serrations.
