Built from alloy steel rated at 170M psi tensile strength and conforming to ASTM A574, this bolt delivers reliable clamping force in demanding mechanical and structural assemblies. The 3\/8-16 UNC thread and 12-point drive head allow for high torque application with standard or crowfoot socket tooling. Partial threading with 1 inch of thread engagement preserves shank strength across the grip length. Licensed tradespeople and industrial maintenance technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for use in mechanical assemblies, structural steel connections, HVAC equipment mounting, pump and compressor frames, and general industrial maintenance where a flanged fastener is specified. The smooth flange face bears evenly against the mating surface, spreading the clamping load and reducing the risk of surface damage or fastener pull-through. The uncoated finish is appropriate for dry indoor installations or applications where a field-applied coating or lubricant will be specified by the job engineer.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlloy steel construction rated to 170M psi tensile strength for high-load applications\u003c\/li\u003e\n  \u003cli\u003eConforms to ASTM A574 standard for socket head cap screws and flange bolts\u003c\/li\u003e\n  \u003cli\u003eSmooth flange face distributes clamping load without a separate washer\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC partially threaded shank with 1 inch of thread length\u003c\/li\u003e\n  \u003cli\u003e12-point drive accepts standard socket or crowfoot tooling for high-torque installation\u003c\/li\u003e\n  \u003cli\u003eUncoated finish for use where coating selection is field- or engineer-specified\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or OEM-style flange bolt for mechanical, structural, and equipment-mounting applications requiring a 3\/8-16 UNC smooth flange fastener conforming to ASTM A574.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or maintenance technician following the torque specifications provided by the equipment manufacturer or project engineer. De-energize and lock out all equipment before fastener service. Use a 12-point socket sized to the 3\/8 inch drive to avoid rounding the head. Verify thread engagement, flange seating, and torque requirements against applicable codes and the assembly drawing before final tightening.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Style\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Type\u003c\/strong\u003e: Smooth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Diameter\u003c\/strong\u003e: 0.550 to 0.562 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: 12 Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 170M psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 706158MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702914187570,"sku":"706158MSC","price":14226.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d51f03292e00229ad9adace96ae64ade.jpg?v=1788413900","url":"https:\/\/voomisupply.com\/products\/value-collection-706158msc-flange-bolt-3-8-16-unc-2-1-2in","provider":"Voomi Supply","version":"1.0","type":"link"}
