It features a 1-1\/2-6 UNC thread size, an 18-inch length under head, and a 1-inch hex drive. The screw is manufactured from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and reduces light reflection. This fastener meets ASME\/ANSI B18.3 and ASTM A574 standards, making it appropriate for structural and mechanical assemblies handled by machinists, millwrights, and maintenance professionals.\u003c\/p\u003e\u003cp\u003eThis socket cap screw is suited for industrial, manufacturing, and mechanical maintenance environments where large-diameter, long-length fasteners are needed. The partial threading allows the unthreaded shank to act as a precision locating or shear feature in bolted joints. Typical applications include heavy machinery assembly, jig and fixture fabrication, and structural mechanical connections requiring a recessed-drive, high-strength fastener.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/2-6 UNC thread for high clamping load in coarse-thread applications\u003c\/li\u003e\n\u003cli\u003e18-inch length under head accommodates deep grip or long clamping stack\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank provides shear strength and precision alignment\u003c\/li\u003e\n\u003cli\u003e1-inch hex drive accepts standard socket or hex key tooling for high-torque installation\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 strength requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish offers mild corrosion resistance and low-glare appearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw compatible with 1-1\/2-6 UNC tapped holes in heavy mechanical and industrial assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or maintenance professional using a calibrated torque wrench and the correct 1-inch hex drive tool. Ensure the mating tapped hole meets 1-1\/2-6 UNC specifications and has sufficient thread engagement before seating the fastener. Inspect threads for damage and apply thread lubricant or anti-seize as required by the assembly specification. Follow applicable industry standards and equipment manufacturer guidelines for torque and clamping load requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/2-6 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\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 Coating\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 581222BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699715965234,"sku":"581222BR","price":127.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_1dc73a64-becf-4abd-bf75-d83e59ff061a.jpg?v=1788379689","url":"https:\/\/voomisupply.com\/products\/value-collection-581222br-hex-socket-cap-screw-1-1-2-6-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
