It features a 1-8 UNC thread size with a 6.5-inch length under head and accepts a 3\/4-inch hex drive. Manufactured from alloy steel with a black oxide coating, this fastener meets ASME\/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding environments where tensile strength and corrosion resistance are required. Machinists, maintenance technicians, and assemblers rely on this type of fastener for securing heavy components in machinery, fixtures, and fabricated structures.\u003c\/p\u003e\u003cp\u003eThis socket cap screw is suited for general industrial and mechanical assembly work where a recessed drive style is preferred for torque application in confined spaces. The partial threading allows for controlled clamping force against unthreaded shank sections, which is important in bolted joints requiring precise alignment or shear load transfer. It is commonly installed in manufacturing equipment, tooling fixtures, hydraulic systems, and structural steel assemblies requiring a flush or near-flush fastener profile.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-8 UNC thread size for compatibility with standard unified coarse-thread fastener systems\u003c\/li\u003e\n\u003cli\u003e6.5-inch length under head provides reach for thick stock or stacked material applications\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank supports shear loading and precise joint alignment\u003c\/li\u003e\n\u003cli\u003e3\/4-inch hex socket drive for high-torque installation with standard hex keys or drive tools\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 for high tensile and proof load requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection in service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard-specification fastener for 1-8 UNC threaded holes requiring a hex socket cap screw per ASME\/ANSI B18.3 and ASTM A574 standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or assembler using a calibrated torque wrench and the appropriate 3\/4-inch hex key or socket drive. Always verify thread engagement depth and hole condition before installation, and ensure mating threads are clean and free of debris. Follow applicable torque specifications per ASME or equipment manufacturer guidelines for the fastener grade and joint material. Do not exceed rated torque or use impact tools without verifying fastener and joint suitability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 6.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.68 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 011549BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699856245042,"sku":"011549BR","price":18.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c2110dc71b6394f1ae2315784415a60.jpg?v=1788382044","url":"https:\/\/voomisupply.com\/products\/value-collection-011549br-hex-socket-cap-screw-1-8-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
