It features a 5\/16-18 UNC thread with a 2-3\/4 inch length under head and is fully threaded from tip to flange. The integrated serrated flange measures 0.68 inches in diameter and bites into the mating surface to resist loosening under vibration without a separate washer. Manufactured from Grade 5 steel with a zinc-plated finish, it meets ASME B18.6.3 and SAE J429 standards. This bolt is driven with a standard hex wrench or socket. Installers in HVAC, plumbing, electrical, and general mechanical trades use this fastener wherever a washer-face and anti-vibration grip are needed in a single component.\u003c\/p\u003e\u003cp\u003eThis serrated flange bolt is suited for residential and light commercial applications where vibration resistance is a priority. Common installation scenarios include equipment mounting, bracket attachment, sheet metal assemblies, and mechanical enclosures. The fully threaded shank provides consistent clamping across the full length, making it practical for through-bolting thin materials. It is sold individually with a minimum order quantity of 50 units per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSerrated flange face locks against mating surface to resist vibration loosening\u003c\/li\u003e\n\u003cli\u003eFully threaded 5\/16-18 UNC shank over the full 2-3\/4 inch length under head\u003c\/li\u003e\n\u003cli\u003e0.68 inch flange diameter distributes clamping load without a separate washer\u003c\/li\u003e\n\u003cli\u003eGrade 5 steel construction meets SAE J429 mechanical requirements\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish provides basic corrosion resistance for indoor and sheltered applications\u003c\/li\u003e\n\u003cli\u003eHex drive compatible with standard sockets and wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNC serrated flange bolt for use in any application requiring a 5\/16-18 thread.

Ensure the mating surface is clean and flat so the serrated flange seats fully and engages evenly. De-energize or shut down any equipment before fastener replacement or maintenance. Do not reuse fasteners that show thread damage, deformation of the flange serrations, or corrosion that compromises the zinc coating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2-3\/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 Diameter\u003c\/strong\u003e: 0.68 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Type\u003c\/strong\u003e: Serrated\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0628 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 825102MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701790703922,"sku":"825102MSC","price":5521.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3876c34398ea25a34ea888763bcad3f0.jpg?v=1788405050","url":"https:\/\/voomisupply.com\/products\/value-collection-825102msc-serrated-flange-bolt-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
