It features a 1-8 UNC thread size with a 4.5-inch length under the head and is driven by a 3\/4-inch hex key. Constructed from alloy steel with a black oxide coating, this fastener delivers reliable tensile strength and moderate corrosion resistance in demanding environments. The partial threading allows for controlled clamping force and is suited for through-bolt and tapped-hole configurations. Licensed mechanics, millwrights, and maintenance technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis socket cap screw is appropriate for heavy equipment assembly, machine tool fixturing, and general industrial maintenance where a recessed-drive, high-strength fastener is required. The 1-8 UNC coarse thread pitch is widely used in ferrous metal applications and provides strong pull-out resistance in tapped steel components. The black oxide finish reduces galling during installation and provides light surface protection in low-moisture environments. It ships as a single unit and is suited for both repair and new-build work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-8 UNC coarse thread for strong engagement in tapped steel and iron\u003c\/li\u003e\n  \u003cli\u003e4.5-inch length under head accommodates thicker stack-ups and through-bolt applications\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a smooth bearing surface and accurate clamping\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 and IFI 124 standards for high tensile strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating reduces friction and provides light corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch hex drive accepts standard hex keys and T-handle drivers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw suitable for industrial machinery, structural assemblies, and mechanical equipment requiring a 1-8 UNC high-strength fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by millwrights, maintenance mechanics, or industrial technicians using a 3\/4-inch hex key or socket driver. Ensure the mating tapped hole is clean, properly sized, and free of debris before installation. Apply thread lubricant or anti-seize compound as appropriate for the service environment to achieve accurate clamp load. Follow applicable torque specifications from a recognized fastener standard or equipment OEM documentation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4.5 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 Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/4 inch\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, IFI 124\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: 1.27 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: 015541BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698594906418,"sku":"015541BR","price":21.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a00d342cfa4e2c727f97869cd9a7bb13.jpg?v=1788365226","url":"https:\/\/voomisupply.com\/products\/value-collection-015541br-hex-socket-cap-screw-1-8-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
