Value Collection 825056MSC Serrated Flange Bolt 1/4-20 Unc

Product Description

The VALUE COLLECTION 825056MSC is a serrated flange bolt designed for secure fastening in applications where a built-in locking feature is required. The serrated flange distributes clamping load across a wider surface area while the teeth grip the mating material to resist loosening under vibration. Manufactured from Grade 5 steel with a zinc-plated finish for corrosion resistance, this bolt measures 3/4 inch in length under the head and is fully threaded with a 1/4-20 UNC thread form. It meets ASME B18.6.3 and SAE J429 standards. Installed using a standard hex drive, it is a common choice for mechanical assemblies, equipment panels, and light structural connections across industrial and commercial trades.

This bolt is suited for general mechanical and structural fastening tasks where a hex-drive serrated flange fastener in the 1/4-20 UNC thread size is specified. Typical installations include equipment enclosures, mounting brackets, sheet metal assemblies, and panel fabrication work in manufacturing, HVAC equipment assembly, electrical enclosures, and general industrial maintenance. The fully threaded shank maximizes thread engagement across the full grip length, making it appropriate for thin-material or short-engagement applications. Sold individually with a minimum order quantity of 100 pieces.

Key Features

• Serrated flange bearing surface resists loosening under vibration without a separate lock washer
• Fully threaded 1/4-20 UNC shank for maximum thread engagement in short-grip applications
• Grade 5 steel construction meets SAE J429 mechanical property requirements
• Zinc-plated finish provides basic corrosion protection for indoor and sheltered environments
• 0.56 inch flange diameter distributes clamping load over a larger bearing area
• Hex drive compatible with standard sockets, wrenches, and nut drivers
• Conforms to ASME B18.6.3 dimensional standards for consistent fit and interchangeability

Compatibility

Designed as a standard 1/4-20 UNC serrated flange bolt conforming to ASME B18.6.3 and SAE J429, suitable for use in any application specifying a Grade 5 fully threaded hex flange bolt in this thread size and length.

Installation Notes

Installation is performed with a standard hex socket or open-end wrench sized for a 1/4-20 hex flange bolt head. Ensure mating threads are clean and free of debris before installation. Do not exceed the torque range appropriate for 1/4-20 Grade 5 fasteners as specified by the equipment manufacturer or applicable industry standards. Zinc-plated fasteners are intended for dry or sheltered environments and are not recommended as a direct replacement for stainless or hot-dip galvanized hardware in corrosive or outdoor-exposed conditions.
