It features a 1-1\/2-12 UNF thread size, a 5-inch length under head, and a 1-inch hex drive socket. Constructed from alloy steel with a black oxide coating, it delivers both mechanical strength and corrosion resistance in demanding service environments. Partial threading along the shank allows for controlled clamping load and is well suited to applications where thread engagement must be limited to a specific grip zone. This fastener meets ASME\/ANSI B18.3 and ASTM A574 standards.\u003c\/p\u003e\u003cp\u003eThis screw is intended for use in industrial, mechanical, and structural assemblies where a fine-thread, large-diameter socket cap screw is specified. Typical applications include heavy machinery, tooling fixtures, die sets, and precision mechanical assemblies. The fine 12 TPI pitch of the UNF thread provides superior resistance to vibration loosening compared to coarse-thread equivalents, making it a common choice in load-bearing joints subject to dynamic forces. Installation is performed with a 1-inch hex key or socket drive tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/2-12 UNF fine thread for superior vibration resistance and precise torque control\u003c\/li\u003e\n\u003cli\u003e5-inch length under head accommodates deep grip zones in thick assemblies\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank for controlled clamp load and accurate joint design\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction provides high tensile and shear strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish adds corrosion resistance and reduces light reflection in service environments\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 standards for dimensional and mechanical compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or build fastener for any assembly specifying a 1-1\/2-12 UNF partially threaded hex socket cap screw conforming to ASME\/ANSI B18.3 and ASTM A574.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified mechanical or industrial tradespeople using a calibrated 1-inch hex key or socket drive. Always verify mating thread condition and hole depth before installation. Torque to the value specified by the joint design engineer or applicable machine manufacturer documentation — do not use generic torque tables without confirming material and coating factors. Apply thread lubricant or anti-seize only if specified by the assembly procedure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/2-12 UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 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: 1 inch\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\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3 and ASTM A574\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: 581967BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709782098226,"sku":"581967BR","price":77.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_3a67a4a9-394f-4ac1-8e6f-2105dbd4b063.jpg?v=1788460373","url":"https:\/\/voomisupply.com\/products\/value-collection-581967br-hex-socket-cap-screw-1-1-2-12-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
