The integrated serrated flange distributes clamp load across a wider bearing surface and bites into the mating material to resist loosening under dynamic loads. This bolt features a 3\/8-16 UNC thread, is fully threaded along its 1-1\/4 inch length under head, and carries a Grade 5 steel rating for reliable tensile strength in moderate-duty applications. A zinc-plated finish provides basic corrosion resistance. Licensed tradespeople and maintenance technicians working on equipment assemblies, brackets, and panel mounts are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for residential and light commercial mechanical applications where a standard hex bolt with a separate washer would otherwise be required. The serrated flange eliminates the need for a lock washer in many installations, streamlining assembly on HVAC equipment frames, electrical enclosures, plumbing support brackets, and general sheet-metal assemblies. The 3\/8-16 UNC thread is among the most common inch-series coarse thread sizes in North American trade work, making this bolt a frequent go-to for replacement and production fastening tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSerrated flange integrates bearing surface and locking function, eliminating a separate lock washer\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC coarse thread for broad compatibility with standard inch-series tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003eFully threaded along the 1-1\/4 inch length under head for maximum thread engagement in thin or short-clearance materials\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction meets SAE J429 mechanical property requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides baseline corrosion protection for indoor and sheltered applications\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.6.3 dimensional standards for hex head bolts and screws\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series serrated flange bolt compatible with any application calling for a 3\/8-16 UNC fully threaded hex flange fastener per ASME B18.6.3 and SAE J429 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard hex wrench or socket driver sized for the hex head. De-energize or shut down any equipment before accessing fastener locations on live assemblies. The serrated flange requires a clean, flat mating surface to function correctly — do not install over existing washers or heavily painted surfaces where the serrations cannot engage. Consult applicable mechanical codes and equipment manufacturer torque specifications for final tightening requirements.\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: 1-1\/4 inches\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: 0.81 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 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B18.6.3, SAE J429\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0605 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: 825118MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690633003314,"sku":"825118MSC","price":8379.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/11eed2e252ad519ec0b35547ac97a81c.jpg?v=1788273007","url":"https:\/\/voomisupply.com\/products\/value-collection-825118msc-serrated-flange-bolt-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
