Value Collection KP24746 3/8-16 Unc Serrated Flange Bolt 50pk

Product Description

The VALUE COLLECTION KP24746 is a serrated flange bolt designed for secure, vibration-resistant fastening in mechanical and structural assemblies. The integrated serrated flange distributes clamping load across a wider bearing surface while the serrations bite into the mating material to resist loosening under vibration. The bolt features a 3/8-16 UNC thread, a 2-inch length under head, and is fully threaded from head to tip. Manufactured from Grade 5 steel with a zinc-plated finish, it meets ASME B18.6.3 and SAE J429 standards. This SKU ships in a package quantity of 50.

Serrated flange bolts in this size range are widely used in HVAC equipment assembly, electrical enclosure mounting, light structural fabrication, and general mechanical applications where a separate washer is impractical or undesirable. The 3/8-16 UNC thread is a common size across commercial and residential equipment panels, brackets, and frames. Grade 5 steel provides sufficient tensile strength for most medium-duty fastening applications encountered by HVAC technicians, electricians, and mechanical contractors.

Key Features

• Serrated flange distributes load and resists loosening under vibration without a separate washer
• 3/8-16 UNC thread, fully threaded for maximum engagement flexibility
• 2-inch length under head suits medium-depth through-bolting applications
• Grade 5 steel construction meets SAE J429 tensile strength requirements
• Zinc-plated finish provides basic corrosion resistance in indoor and sheltered environments
• Conforms to ASME B18.6.3 dimensional standards for consistent fitment

Compatibility

Designed as a standard-dimension 3/8-16 UNC serrated flange bolt per ASME B18.6.3, suitable for use in any application requiring a hex-drive fully threaded flange bolt in this thread size and length.

Installation Notes

Installation requires a standard hex socket or open-end wrench sized for 3/8-16 fasteners. Ensure mating threads are clean and free of debris before driving. Do not exceed the torque rating appropriate for Grade 5 steel at this thread diameter as specified by the equipment manufacturer or relevant fastener standards. Zinc-plated fasteners are intended for indoor or sheltered use and should not be substituted for stainless or hot-dip galvanized hardware in corrosive or outdoor-exposure environments.
