The bolt measures 1-3\/4 inches in length under the head and ships in a pack of 100 pieces. Grade B7 alloy steel offers elevated tensile and yield strength compared to standard carbon steel fasteners, making this bolt suitable for demanding bolting applications where higher proof loads are required. The uncoated finish is standard for environments where additional plating or coating will be applied or is not required. Mechanical and plumbing contractors, pipefitters, and structural tradespeople will find this bolt appropriate for high-strength assembly work.\u003c\/p\u003e\n\u003cp\u003eThis hex head bolt is commonly used in flanged pipe connections, pressure vessel assemblies, structural steel fabrication, and general industrial bolting where ASTM A193 Grade B7 material certification is specified. The 1\/4-20 UNC thread is a widely used coarse-thread series in inch-measurement fastener applications. The pack quantity of 100 pieces suits job-site use or shop stock replenishment for contractors and maintenance operations that require certified fasteners in quantity.\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\u003e1\/4-20 UNC coarse thread series in inch measurement system\u003c\/li\u003e\n  \u003cli\u003e1-3\/4 inch length measured under the head\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for further processing or standard assembly use\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 100 pieces for production and job-site efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC hex head bolt for use in applications requiring ASTM A193 Grade B7 certified fasteners, including flanged pipe joints, pressure equipment, and structural assemblies governed by applicable fastener specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified pipefitter, millwright, plumber, or mechanical contractor familiar with fastener torque specifications for the application and joint design. Verify that mating nut material and thread class are compatible with 1\/4-20 UNC before assembly. Follow applicable codes and engineering specifications for preload and torque values, as these are determined by joint design and are not provided with the fastener. Inspect threads for damage before installation and discard any bolt that shows cross-threading or deformation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\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: 100 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 49005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711935414578,"sku":"49005","price":1120.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/afa41e609d99d473c9ffcabf32854133.jpg?v=1788481627","url":"https:\/\/voomisupply.com\/products\/value-collection-49005-1-4-20-hex-bolt-alloy-steel-grade-b7-100pk","provider":"Voomi Supply","version":"1.0","type":"link"}
