The integrated serrated flange distributes clamping load across a wider surface area and bites into the mating material to resist loosening under vibration. The bolt is fully threaded at 3\/8-16 UNC with a 2.25-inch length under head, making it well suited for through-bolting applications where maximum thread engagement is required. Manufactured from Grade 5 steel with a zinc-plated finish, it meets ASME B18.6.3 and SAE J429 standards. The hex drive allows installation with standard hand tools or power drivers. Electricians, HVAC technicians, and general mechanical tradespeople commonly use this fastener type in panel mounting, equipment support, and structural bracketing work.\u003c\/p\u003e\n\u003cp\u003eThis bolt is used in residential and light commercial mechanical installations where a flanged, vibration-resistant fastener is needed without a separate washer. The serrated flange face grips the workpiece surface on tightening, maintaining clamp load in applications subject to thermal cycling or equipment vibration. Fully threaded construction makes it suitable for use with nuts or threaded plate assemblies where adjustable engagement depth is required. The 3\/8-16 UNC thread is a widely used coarse-thread standard across HVAC equipment frames, electrical enclosures, and mechanical support structures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFully threaded 3\/8-16 UNC for maximum thread engagement and flexible nut positioning\u003c\/li\u003e\n  \u003cli\u003eSerrated flange face resists loosening under vibration without a separate lock washer\u003c\/li\u003e\n  \u003cli\u003eFlange diameter of 0.81 inches provides expanded bearing surface for load distribution\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction meets SAE J429 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance in indoor and sheltered applications\u003c\/li\u003e\n  \u003cli\u003eHex drive compatible with standard wrenches and socket sets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8-16 UNC serrated flange bolt for use in any application requiring an ASME B18.6.3-compliant inch-series hex flange fastener with Grade 5 strength and zinc-plated finish.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a hex wrench or socket driver sized for the hex head. Power down or de-energize any equipment before fastening or removing hardware on electrical or HVAC assemblies.
