Manufactured from alloy steel to Grade B7 per ASTM A193, this bolt carries a 1\/2-13 UNC thread and measures 1-3\/4 inches in length under head. The uncoated finish makes it suitable for applications where a secondary coating, plating, or lubricant will be applied in the field. Grade B7 alloy steel is a common specification for pressure vessel flanges, high-temperature piping, and structural bolting work encountered in mechanical, industrial, and process piping installations.\u003c\/p\u003e\u003cp\u003eThis bolt is typically used in commercial and industrial settings where ASTM A193 compliance is required by code or engineering specification. Common applications include pipe flange assemblies, pressure equipment, heat exchangers, and structural connections in mechanical rooms and process facilities. Sold in a package quantity of 25, it suits both maintenance stock and small-batch installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade B7 alloy steel construction meets ASTM A193 fastener standard for high-strength applications\u003c\/li\u003e\n\u003cli\u003e1\/2-13 UNC thread for broad compatibility with standard inch-series nuts and threaded components\u003c\/li\u003e\n\u003cli\u003e1-3\/4 inch length under head for precise fitment in flange and structural connections\u003c\/li\u003e\n\u003cli\u003eUncoated finish allows field application of coatings, lubricants, or anti-seize compounds\u003c\/li\u003e\n\u003cli\u003ePackage quantity of 25 supports maintenance kits and small-volume bolting jobs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or maintenance stock fastener for applications requiring 1\/2-13 UNC hex head bolts conforming to ASTM A193 Grade B7 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic, pipefitter, or millwright familiar with ASTM fastener specifications and applicable torque procedures for the joint being assembled. Always de-energize, depressurize, and isolate the system before replacing fasteners on live piping or pressure equipment. Refer to the applicable engineering specification or flange standard for proper torque values and lubrication requirements, as these are joint-specific and not defined by the fastener alone. Follow ASME, IFGC, or facility-specific bolting procedures as required by the installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\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: 1-3\/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\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 49052\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51973889065266,"sku":"49052","price":64.14,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1e1a7a9f4e17565263f4b5d46ca1c77.jpg?v=1789974913","url":"https:\/\/voomisupply.com\/products\/value-collection-49052-hex-head-bolt-1-2-13-alloy-steel-b7","provider":"Voomi Supply","version":"1.0","type":"link"}
