Each stud measures 1-1\/8 inches in diameter with 8 threads per inch (1-1\/8-8 UNC thread form) and runs 7 inches in overall length. The uncoated finish leaves the base steel exposed, which is common in high-temperature and high-pressure bolting applications where coatings can interfere with torque values or chemical compatibility. The 7B thread fit class indicates a close-tolerance internal thread designed for precision engagement. Each package includes 4 studs and 8 nuts. Mechanical contractors, pipefitters, and industrial maintenance techs use this stud-and-nut assembly for flanged connections, pressure vessel bolting, and structural fastening in demanding service environments.\u003c\/p\u003e\n\u003cp\u003eThis stud assembly is suited for flanged pipe joints, pressure vessel covers, heat exchanger heads, and similar bolted connections in industrial and commercial mechanical systems. The ASTM A193 Grade B7 designation is widely specified in petrochemical, refinery, power generation, and HVAC industrial piping systems where elevated temperature and high-stress bolting is required. The included nuts are sized to match the 1-1\/8-8 thread and 7B fit class. Each pack of 4 studs and 8 nuts provides enough hardware for a single four-bolt flange connection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade B7 alloy steel construction meets ASTM A193 specification for high-strength bolting\u003c\/li\u003e\n  \u003cli\u003e1-1\/8-8 thread size with 7B class of fit for precise, close-tolerance engagement\u003c\/li\u003e\n  \u003cli\u003e7 inches overall length accommodates standard industrial flange stack-ups\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for use where surface treatments are not specified\u003c\/li\u003e\n  \u003cli\u003eEach package includes 4 studs and 8 nuts, ready for immediate installation\u003c\/li\u003e\n  \u003cli\u003eUNSPSC Code 31163300 for procurement system compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fastener for industrial flanged assemblies requiring ASTM A193 Grade B7 fully threaded studs with a 1-1\/8-8 thread form and 7B class of fit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified pipefitter or mechanical contractor following applicable ASME, ASTM, and site-specific torque procedures. De-energize, depressurize, and isolate the system before removing or installing flange fasteners. Inspect threads for damage before assembly and confirm nut seating is flush before applying final torque. Do not mix Grade B7 studs with non-matching nut grades, as mismatched hardware can compromise joint integrity under pressure and temperature cycling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/8-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches\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: B7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: 7B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM A193\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Contents\u003c\/strong\u003e: 4 Studs, 8 Nuts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0153 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: B7SN1130700UP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714116845874,"sku":"B7SN1130700UP","price":148.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/40fc6fcaf4aade454ffb1a8f374f7092_80f92543-acb7-4017-97e8-29e13c2101fc.jpg?v=1788496456","url":"https:\/\/voomisupply.com\/products\/value-collection-b7sn1130700up-threaded-stud-nut-1-1-8-8-steel-b7","provider":"Voomi Supply","version":"1.0","type":"link"}
