It is threaded 1-14 UNF, indicating a 1-inch nominal diameter with a fine thread pitch of 14 threads per inch. The fastener measures 8 inches in length under the head and uses a 3\/4-inch hex (Allen) socket drive. Constructed from alloy steel with a black oxide finish, it delivers solid mechanical strength and moderate corrosion resistance in controlled environments. This fastener is partially threaded, which is standard for longer cap screws used in load-bearing joints. It is typically installed by machinists, millwrights, and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for heavy industrial, mechanical, and structural applications where a flush or recessed fastener head is required. The 1-14 UNF thread form provides finer thread engagement than coarse-thread equivalents, making it appropriate for applications that demand precise torque control or where vibration resistance is a priority. It is commonly used in machine frames, fixtures, die sets, and heavy equipment assemblies. The partial thread pattern allows for full bearing load to be carried through the unthreaded shank in clearance-hole applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-14 UNF fine thread form for precise thread engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e8 inches of length under head accommodates deep or stacked assemblies\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch hex socket drive for use with standard Allen keys or hex socket drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank suitable for shear-loaded clearance-hole joints\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and aftermarket replacement hex socket cap screw for industrial machinery, structural fixtures, and mechanical assemblies requiring a 1-14 UNF thread specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified machinists, millwrights, or maintenance technicians familiar with torque requirements for alloy steel fasteners of this thread class. De-energize and lock out all equipment before fastener installation or removal in accordance with applicable OSHA lockout\/tagout procedures. Use a properly sized 3\/4-inch hex socket or Allen key to avoid rounding the drive socket. Apply a thread lubricant or anti-seize compound as appropriate for the joint design and service environment to achieve accurate clamp load during torque application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-14 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 8 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\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3 and ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 581856BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701559787826,"sku":"581856BR","price":40.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_e66750ff-4757-47c8-993c-ed1abb4d6e10.jpg?v=1788401489","url":"https:\/\/voomisupply.com\/products\/value-collection-581856br-hex-socket-cap-screw-1-14-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
