It features a 7\/8-9 UNC thread size and measures 4 inches in length under the head. The 3\/4-inch hex drive accepts a standard hex key or Allen-head socket for installation and removal. Constructed from alloy steel with a black oxide coating, this cap screw provides solid mechanical performance and moderate corrosion resistance in shop and industrial environments. It meets ASME\/ANSI B18.3 and ASTM A574 standards, confirming it is manufactured to recognized dimensional and mechanical property specifications.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in machine frames, jigs, fixtures, and general industrial assemblies where a flush or recessed drive fastener is required. The partial threading allows for precise clamping when the shank bears against a close-tolerance hole. Machinists, millwrights, and maintenance technicians commonly install this type of fastener in manufacturing facilities, fabrication shops, and field maintenance applications. It is sold in a minimum order quantity of 5 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8-9 UNC thread size for high load-bearing capacity in standard unified coarse thread applications\u003c\/li\u003e\n  \u003cli\u003e4-inch length under head with partial threading for controlled clamping force\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch hex drive for use with standard hex keys or socket drive tools\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical property requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection in precision setups\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and general-use replacement or stocking fastener for applications requiring 7\/8-9 UNC partially threaded hex socket cap screws per ASME\/ANSI B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a calibrated torque wrench with a 3\/4-inch hex bit to achieve the appropriate torque for the joint material and application. Ensure mating threads are clean and free of debris before installation. De-energize and lock out any machinery before accessing fastener locations on powered equipment. Do not use impact drivers on precision-fit socket cap screws without confirming torque limits for 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: 7\/8-9 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/4 inches\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 Coating\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3 and ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: -33709-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707038138674,"sku":"-33709-1","price":46.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2ac3ca74f4e95cd6316256f9cfa6942c.jpg?v=1788437994","url":"https:\/\/voomisupply.com\/products\/value-collection-33709-1-hex-socket-cap-screw-7-8-9-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
