Sized at 3\/8-16 UNC with a 3-inch length under head, this bolt features an integrated serrated flange that bites into the mating surface to resist loosening under vibration. Manufactured from AISI C1022 steel to Grade 2 specification, it carries a zinc-plated finish for basic corrosion resistance. The hex drive allows installation with standard hex tooling. This fastener is used by mechanical assemblers, maintenance technicians, HVAC and equipment installers, and general tradespeople who need a reliable anti-loosening bolt without a separate washer.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for residential and light commercial assembly work where vibration is a concern and a separate flange washer is not preferred. Common applications include equipment mounting, bracket attachment, HVAC unit assembly, and general structural fastening on steel and similar substrates. The serrated flange bearing surface distributes clamp load across a wider area than a standard hex bolt, reducing the risk of surface damage and improving joint integrity. It is sold individually with a minimum order quantity of 10 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSerrated flange resists loosening under vibration without a separate lock washer\u003c\/li\u003e\n  \u003cli\u003eFully threaded 3\/8-16 UNC thread along the full 3-inch length under head\u003c\/li\u003e\n  \u003cli\u003eFlange diameter of 0.771 to 0.793 inches provides wider load distribution\u003c\/li\u003e\n  \u003cli\u003eAISI C1022 Grade 2 steel construction for standard-duty fastening applications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers basic corrosion protection in dry to mildly humid environments\u003c\/li\u003e\n  \u003cli\u003eHex drive compatible with standard sockets and wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension 3\/8-16 UNC fully threaded serrated flange bolt suitable for use in any application requiring that thread size, length, and flange style per inch-system fastener standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a standard hex socket or open-end wrench sized for 3\/8-inch hex flange bolts.
