It features a 1-8 UNC thread size, an 8-inch length under head, and accepts a 3\/4-inch hex drive. The alloy steel construction with black oxide coating provides corrosion resistance and reduces galling during installation. This fastener meets ASME B18.3 and ASTM A574 standards, making it suitable for demanding structural and machinery applications. Maintenance technicians, millwrights, and industrial mechanics typically install this screw where high tensile strength and a clean, low-profile socket head are required.\u003c\/p\u003e\n\u003cp\u003eThe 72396 is appropriate for use in heavy equipment, industrial machinery, structural fixtures, and mechanical assemblies where a partially threaded cap screw is called for. The coarse 1-8 UNC thread pitch is well suited for applications requiring quick engagement and strong clamping force in steel or iron tapped holes. The black oxide finish helps resist light moisture exposure in shop and field environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-8 UNC coarse thread for strong engagement in steel and iron components\u003c\/li\u003e\n  \u003cli\u003e8-inch length under head with partial threading for precise clamping control\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch internal hex drive for high-torque installation with standard hex keys or drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 high-strength fastener specification\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating provides mild corrosion resistance and reduces light surface oxidation\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.3 socket cap screw dimensional standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME B18.3 socket cap screw for use in tapped holes requiring a 1-8 UNC thread engagement in industrial, mechanical, and structural assemblies.\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. Verify tapped hole thread condition and depth before installation to ensure full thread engagement. Apply appropriate thread lubricant or anti-seize compound per shop practice to prevent galling on alloy steel fasteners. Follow applicable torque specifications from your engineering reference for ASTM A574 alloy steel cap screws at this thread size.\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: 8 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 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.3 and 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: 72396\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51740186018098,"sku":"72396","price":73.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8809f1e03293b2386191737b2d93f97f.jpg?v=1788823301","url":"https:\/\/voomisupply.com\/products\/holo-krome-72396-hex-socket-cap-screw-1-8-unc-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
