It features an 8-32 UNC thread with a 4-inch length under the head, driven by a 9\/64-inch hex socket key. Constructed from alloy steel with a black oxide coating, this screw offers solid tensile strength and mild corrosion resistance. It meets ASME\/ANSI B18.3 and ASTM A574 standards, making it a reliable choice for load-bearing and close-tolerance fastening tasks encountered by millwrights, machinists, and maintenance mechanics.\u003c\/p\u003e\u003cp\u003eThis cap screw is suited for general industrial and mechanical applications where a socket drive provides torque access in confined spaces. The black oxide finish is commonly used in tooling fixtures, machine frames, enclosures, and low-moisture interior environments. Partial threading allows for clamping force without thread engagement through the full grip length, which is appropriate for applications requiring a precise clamping zone.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-32 UNC thread size for fine machine-thread fastening\u003c\/li\u003e\n\u003cli\u003e4-inch length under head with partial threading for controlled clamp zone\u003c\/li\u003e\n\u003cli\u003e9\/64-inch hex socket drive for use with standard Allen keys or hex drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating provides mild corrosion resistance and reduced surface reflectivity\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\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 suitable for machine assemblies, fixtures, and equipment requiring an 8-32 UNC partially threaded fastener.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 9\/64-inch hex key or socket driver. Ensure mating threaded holes are clean, properly tapped to 8-32 UNC, and free of debris before installation. Power down and de-energize any equipment before fastener service. Apply consistent torque within the limits appropriate for alloy steel at this thread size; consult ASME torque tables or a fastener reference guide for your specific joint design.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4 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: 9\/64 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, ASTM A574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 581267PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723888427314,"sku":"581267PR","price":1187.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b2cd19c2b6bf9bb19c28a0967c82ff2e.jpg?v=1788609402","url":"https:\/\/voomisupply.com\/products\/value-collection-581267pr-hex-socket-cap-screw-8-32-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
