Threaded 1-8 UNC with a 2.5-inch length under head and a 0.75-inch hex drive, this screw is fully threaded along its shaft. It is manufactured from alloy steel and finished with a black oxide coating, which provides mild corrosion resistance and reduces light reflection in service environments. Licensed tradespeople, millwrights, and maintenance technicians working on equipment assemblies, machine frames, and structural fixtures are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for use in mechanical assemblies, industrial equipment, and structural connections where a recessed hex drive is preferred over an external fastener head. The 1-8 UNC coarse thread pitch is widely used in general-purpose steel-to-steel fastening and is standard in many machine and equipment builds. The black oxide alloy steel construction makes it appropriate for indoor or low-moisture environments where higher tensile strength is required compared to standard hardware-grade fasteners.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-8 UNC coarse thread for reliable engagement in steel components\u003c\/li\u003e\n  \u003cli\u003eFully threaded shaft along the 2.5-inch length under head\u003c\/li\u003e\n  \u003cli\u003e0.75-inch hex socket drive for use with standard Allen or hex keys\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASME B18.3 and ASTM A574 standards\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and low-glare appearance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-fit hex socket cap screw for industrial and mechanical assemblies requiring a 1-8 UNC, fully threaded alloy steel fastener per ASME B18.3 and ASTM A574 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified tradespeople or maintenance technicians using a calibrated hex key or Allen driver sized to 0.75 inches. Ensure mating threads are clean and free of debris before installation. Follow applicable torque specifications from the equipment manufacturer or relevant ASME guidelines for the fastener grade. Do not use impact tools without confirming thread engagement to avoid cross-threading or fastener damage.\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: 2.5 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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully 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 B18.3, ASTM A574\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: HOLO-KROME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 72372\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51741859971378,"sku":"72372","price":24.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/435987c8c9c59696e7c7493752e2aba4.jpg?v=1788833883","url":"https:\/\/voomisupply.com\/products\/holo-krome-72372-hex-socket-cap-screw-1-8-unc-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
