It carries a 7\/8-9 UNC thread and measures 3 inches in length under the head with full threading along the entire shank. The drive is a 3\/4-inch hex socket, which accepts a standard Allen or hex key drive tool. Constructed from alloy steel with a black oxide finish, the fastener delivers high tensile strength and moderate corrosion resistance in protected or lightly exposed environments. It meets ASME B18.3 and ASTM A574 standards. Licensed tradespeople and industrial maintenance technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis cap screw is suited for use in heavy equipment, machine tool frames, jigs, fixtures, and general mechanical assemblies where a recessed drive head and high clamp load are required. The fully threaded shank allows engagement along the full 3-inch length, making it appropriate for through-bolting or threading into blind holes with adequate depth. It is sold as a single unit with a minimum order quantity of one.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/8-9 UNC thread form for standard unified coarse-pitch applications\u003c\/li\u003e\n\u003cli\u003e3 inches length under head, fully threaded shank\u003c\/li\u003e\n\u003cli\u003e3\/4-inch hex socket drive accepts standard hex key and torque wrench tooling\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 high-strength requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light glare on the fastener head\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ASME B18.3 hex socket cap screw for use in any application requiring a 7\/8-9 UNC fully threaded fastener with a 3-inch length under head.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or maintenance technician familiar with torque specifications for alloy steel fasteners at this thread size. Use a properly sized 3\/4-inch hex key or socket driver; an undersized driver will damage the socket recess. De-energize and lock out any equipment before fastener installation or removal. Verify thread engagement depth and hole condition before applying final torque.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-9 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully 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\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\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 72346\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51744033669426,"sku":"72346","price":24.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec060f628d94396299b06aedb1f666db.jpg?v=1788853272","url":"https:\/\/voomisupply.com\/products\/holo-krome-72346-hex-socket-cap-screw-7-8-9-unc-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
