The bolt features a 3\/8-16 UNC thread, a fully threaded shank with 1 inch of thread length under the head, and a hex drive for standard wrench or socket installation. The integrated serrated flange distributes clamping load across a wider bearing surface and bites into the mating material to resist rotation. Manufactured from AISI C1022 Grade 2 steel with a zinc-plated finish, this bolt suits general-purpose mechanical and structural assembly work across trades.\u003c\/p\u003e\n\u003cp\u003eThis bolt is used in general industrial, mechanical, and construction assembly where a standard hex bolt with a locking flange face is required. The serrated underside eliminates the need for a separate lock washer in many applications. Common installation scenarios include equipment frames, brackets, HVAC unit mounting, electrical enclosures, and light structural connections. The 3\/8-16 UNC thread is one of the most widely used coarse-thread sizes in inch-standard fastener applications, making this bolt a routine stock item for maintenance and service operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSerrated flange face resists loosening under vibration without a separate lock washer\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank with 1 inch of length under head for maximum thread engagement in thinner materials\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC coarse thread for fast engagement and broad compatibility with standard nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003eHex drive accepts standard wrenches, sockets, and impact drivers\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion resistance for indoor and sheltered outdoor use\u003c\/li\u003e\n  \u003cli\u003eGrade 2 AISI C1022 steel construction meets general-purpose mechanical fastening requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or stock fastener for any application requiring a 3\/8-16 UNC serrated flange bolt with 1 inch of length under head and a hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard hex wrench or socket sized for the bolt head. Power down or de-energize any equipment before accessing fastener points on electrical or mechanical assemblies. The serrated flange requires a clean, flat mating surface to function correctly — do not install over painted or coated surfaces where the serrations cannot seat into the base material. Follow applicable torque guidelines from the equipment manufacturer or relevant standards for 3\/8-16 Grade 2 hardware.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Type\u003c\/strong\u003e: Serrated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Diameter\u003c\/strong\u003e: 0.771 to 0.793 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: AISI C1022\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1.18 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: R52001165\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696357671218,"sku":"R52001165","price":1435.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/af7685315e3a5eb3de604836f7166703.jpg?v=1788341867","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001165-serrated-flange-bolt-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
