Built from alloy steel to Grade B7 specifications and certified to ASTM A193, this bolt delivers reliable clamping force in demanding industrial and mechanical environments. The fastener features a 3\/8-16 UNC thread profile and measures 4 inches in length under the head. It ships in a package quantity of 25, making it suitable for job-lot purchasing on projects requiring multiple fasteners of the same spec.\u003c\/p\u003e\n\u003cp\u003eGrade B7 alloy steel bolts conforming to ASTM A193 are commonly used in flanged piping assemblies, pressure vessels, heat exchangers, and structural mechanical connections. This bolt is appropriate for applications in HVAC mechanical rooms, industrial plumbing systems, and process piping where code-specified fastener grades are required. The uncoated finish makes it well suited for environments where a specific coating or plating will be applied in the field or where bare alloy steel is acceptable per the design specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade B7 alloy steel construction meets ASTM A193 fastener standard for high-strength bolting\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread provides standard coarse-thread engagement for broad hardware compatibility\u003c\/li\u003e\n  \u003cli\u003e4-inch length under head accommodates thicker flanges, gasketed joints, and stacked components\u003c\/li\u003e\n  \u003cli\u003eUncoated finish allows field application of thread lubricants, anti-seize, or plating as needed\u003c\/li\u003e\n  \u003cli\u003eSold in a 25-piece package quantity to support batch fastening work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8-16 UNC hex head bolt for use in flanged piping, pressure vessel, and mechanical assembly applications requiring ASTM A193 Grade B7 alloy steel fasteners.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanical or piping professional familiar with applicable codes including ASME and ANSI piping standards. Depressurize and isolate any system before replacing or installing fasteners on flanged connections or pressure-rated assemblies. Apply thread lubricant or anti-seize compound per the joint specification before torquing. Follow the torque sequence and values specified in the relevant engineering drawing or flange standard — do not estimate torque without consulting the applicable specification.\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: 4 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: Grade B7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM A193\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25\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: 49042\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723090100530,"sku":"49042","price":185.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/59baf6f95e8ac770615c70f05942ca87.jpg?v=1788600466","url":"https:\/\/voomisupply.com\/products\/value-collection-49042-hex-head-bolt-3-8-16-4-in-grade-b7","provider":"Voomi Supply","version":"1.0","type":"link"}
