Value Collection 825060MSC Serrated Flange Bolt 1/4-20 Unc

Product Description

The VALUE COLLECTION 825060MSC is a serrated flange bolt designed for general mechanical and structural fastening applications. It features a 1/4-20 UNC thread with a 1-1/4 inch length under head, fully threaded from the bearing surface to the tip. The integrated serrated flange distributes clamping load across a wider surface area and bites into the mating material to resist loosening under vibration. Manufactured from Grade 5 steel with a zinc-plated finish, this bolt meets ASME B18.6.3 and SAE J429 standards. It is driven with a standard hex tool and suits a wide range of light industrial, automotive, and equipment assembly tasks.

This bolt is commonly used in assemblies where a separate washer is impractical and where vibration resistance is required without a locking insert or adhesive. Typical applications include automotive underhood components, HVAC equipment panels, electrical enclosures, and general sheet metal assemblies. The fully threaded shank allows maximum thread engagement in thinner materials. At 0.022 pounds per unit, it is suited for high-volume fastening work where weight and bulk are factors.

Key Features

• Serrated flange integrates a locking and load-distributing surface in one fastener
• Fully threaded shank provides maximum engagement in thin or short-depth holes
• Grade 5 steel construction meets SAE J429 mechanical property requirements
• Zinc-plated finish provides basic corrosion resistance for indoor and protected outdoor use
• Hex drive head works with standard sockets and wrenches
• Conforms to ASME B18.6.3 dimensional standard for inch-series flange bolts

Compatibility

Designed as a standard inch-series serrated flange bolt for use in any application requiring a 1/4-20 UNC threaded fastener with an integrated flange bearing surface.

Installation Notes

Installation is performed with a hex socket or open-end wrench sized for the hex head. Ensure the mating thread is clean and free of debris before driving. The serrated flange requires firm seating against the workpiece surface to engage the locking serrations — do not install against painted or coated surfaces where serration grip is critical without accounting for finish thickness. Follow applicable torque specifications from the equipment manufacturer or refer to SAE J429 Grade 5 torque tables for the thread size.
