This screw measures 6 inches in length under the head with a 1-3\/8-6 UNC thread size and a 1-inch hex drive. It is partially threaded, which allows for better clamping between mating surfaces. Constructed from alloy steel and finished with a black oxide coating, this fastener resists corrosion in moderate environments while maintaining the high tensile strength typical of ASTM A574-grade socket cap screws. It conforms to ASME\/ANSI B18.3 dimensional standards.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used in mechanical, structural, and industrial assembly applications where a socket-drive cap screw is required. The 1-3\/8-6 UNC coarse thread is suited for general-purpose steel fabrication, machinery mounting, and heavy equipment assembly. The large 1-3\/8-inch diameter makes it appropriate for high-load joints in commercial and industrial settings. Typical installers include millwrights, industrial mechanics, and maintenance technicians working on equipment frames, structural brackets, and fabricated steel assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-3\/8-6 UNC coarse thread for high-load fastening in steel applications\u003c\/li\u003e\n  \u003cli\u003e6-inch length under head accommodates thick material stacking\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank improves clamping performance at joint interfaces\u003c\/li\u003e\n  \u003cli\u003e1-inch hex drive socket interface for use with standard hex keys or drive tools\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 high-strength requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw for use in tapped holes or with nuts accepting 1-3\/8-6 UNC threads in industrial and mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified mechanics or millwrights using a properly sized 1-inch hex key or socket drive tool. Confirm that the mating tapped hole or nut matches the 1-3\/8-6 UNC thread specification before installation. Apply thread lubricant or anti-seize compound as required by the application to achieve accurate torque values. De-energize and lockout any associated equipment before fastener service to comply with applicable safety procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-3\/8-6 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partial\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: 1 inch\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\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0032 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: 581948BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692736938290,"sku":"581948BR","price":153.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6ee76cdcd1e9c00e23fa8660adea989e.jpg?v=1788301976","url":"https:\/\/voomisupply.com\/products\/value-collection-581948br-hex-socket-cap-screw-1-3-8-6-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
