Value Collection 825208MSC Serrated Flange Bolt 1/4-20 Unc

Product Description

The VALUE COLLECTION 825208MSC is a serrated flange bolt designed for secure, vibration-resistant fastening in structural and mechanical assemblies. The serrated flange face bites into the mating surface, locking the fastener in place without a separate washer. At 1/4-20 UNC thread with a 1/2 inch length under head and fully threaded shank, this bolt suits tight-clearance joints where thread engagement along the full length is required. Manufactured from Grade 8 steel with a zinc-plated finish, it meets ASME B18.6.3 and SAE J429 standards. The hex drive allows installation with standard hand or power tools. Machinists, maintenance technicians, and fabricators reach for this fastener in high-load, vibration-prone applications.

This bolt is used in light fabrication, equipment assembly, HVAC bracket mounting, electrical enclosure assembly, and general industrial maintenance where a 1/4-20 UNC serrated flange fastener is called for. The fully threaded design maximizes grip in thin-material applications. The zinc-plated finish provides baseline corrosion resistance for indoor and mildly protected outdoor environments. Sold individually with a minimum order quantity of 100 pieces, making it suitable for production runs and bulk maintenance stock.

Key Features

• Serrated flange face eliminates the need for a separate lock washer and resists loosening under vibration
• Grade 8 steel construction delivers high tensile and proof load strength for demanding fastening applications
• Fully threaded shank provides maximum thread engagement across the 1/2 inch length under head
• Zinc-plated finish offers corrosion resistance in general indoor and light-duty service environments
• Hex drive head is compatible with standard wrenches and sockets
• Meets ASME B18.6.3 and SAE J429 dimensional and mechanical standards

Compatibility

Designed as a standard 1/4-20 UNC serrated flange bolt for use in any application requiring ASME B18.6.3 and SAE J429 compliant Grade 8 fasteners with a 1/2 inch length under head.

Installation Notes

Installation is performed with a standard hex wrench or socket driver sized for the hex flange head. Ensure mating threads are clean and free of debris before driving. Power down or de-energize any equipment before accessing fastener locations on live assemblies. Do not exceed the torque rating appropriate for 1/4-20 Grade 8 fasteners as specified by your application engineering documentation.
