Threaded to the 5\/8-11 UNC standard, it measures 8 inches under the head and accepts a 1\/2-inch hex drive. Constructed from alloy steel with a black oxide coating, this screw meets ASTM A574 specifications, which govern mechanical and dimensional requirements for socket head cap screws. Partial threading along the shank allows for precise clamping force and is suited to through-hole and tapped applications requiring a clean grip area beneath the head.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used in machinery assembly, tooling fixtures, heavy equipment maintenance, and structural bolted connections where high tensile strength and a recessed drive profile are required. The 5\/8-11 UNC coarse thread pitch is widely used in general industrial applications and is compatible with standard UNC tapped holes of the same nominal diameter. Machinists, millwrights, maintenance technicians, and mechanical contractors commonly specify this type of fastener in production and field repair work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC coarse thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e8-inch length under head accommodates deep through-bolting and stacked assembly applications\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex socket drive for torque application with standard hex keys or socket drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements for socket cap screws\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection in precision assemblies\u003c\/li\u003e\n  \u003cli\u003ePartial threading preserves an unthreaded shank section for shear-load and alignment applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use fastener for standard 5\/8-11 UNC tapped holes in industrial machinery, fixtures, and structural assemblies requiring ASTM A574-compliant socket head cap screws.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, millwrights, or maintenance technicians using a 1\/2-inch hex key or socket drive tool. Ensure the mating tapped hole is clean, free of debris, and properly sized to 5\/8-11 UNC before installation. De-energize, lock out, and tag out any equipment before accessing fastener locations on live machinery. Do not exceed the torque capacity of the alloy steel fastener or substitute thread lubricants without confirming compatibility with the joint design.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11 UNC\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: 1\/2 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: ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.72 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 307156BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723018076466,"sku":"307156BR","price":24.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c3d4393290d1151337a0e6cc1706718c_0d9c2455-592d-4bf3-94f5-687a9ceb1628.jpg?v=1788599330","url":"https:\/\/voomisupply.com\/products\/value-collection-307156br-hex-socket-cap-screw-5-8-11-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
