It features a 7\/8-9 UNC thread and measures 3-1\/2 inches under the head, with partial threading along the shank. The 3\/4-inch hex drive accepts a standard hex key or socket driver. Manufactured from alloy steel with a black oxide finish, it provides good corrosion resistance and a consistent surface for high-load fastening. Licensed tradespeople and maintenance mechanics use this fastener in machine frames, equipment housings, and structural assemblies requiring a flush or recessed head profile.\u003c\/p\u003e\u003cp\u003eThis cap screw suits heavy-duty bolted connections in manufacturing, maintenance, and industrial construction settings. The 7\/8-9 UNC coarse thread is a standard choice where vibration resistance and ease of assembly in field conditions are priorities. Its partial threading allows for shank engagement in clearance holes, making it well suited for tight-tolerance joints. The black oxide alloy steel construction meets ASME\/ANSI B18.3 and ASTM A574 standards, making it appropriate for demanding structural and mechanical fastening tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/8-9 UNC coarse thread for reliable field assembly and vibration resistance\u003c\/li\u003e\n\u003cli\u003e3-1\/2 inches length under head with partial threading for shank-bearing clearance fits\u003c\/li\u003e\n\u003cli\u003e3\/4-inch hex socket drive compatible with standard hex keys and socket drive tools\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meeting ASTM A574 for high tensile strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for moderate corrosion and wear resistance\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw for use in any application requiring a 7\/8-9 UNC partially threaded socket head fastener in alloy steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or maintenance professional using a correctly sized 3\/4-inch hex key or socket drive tool. Ensure mating threads are clean and free of debris before assembly. De-energize or lock out any equipment before fastener service per applicable OSHA lockout\/tagout procedures. Do not substitute a smaller drive size, as rounding the socket can compromise torque application and fastener integrity.\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: 3-1\/2 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: 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\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: -33708-31\/2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712782663986,"sku":"-33708-31\/2","price":57.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/050b743314cda01f370a313ee442555f.jpg?v=1788488571","url":"https:\/\/voomisupply.com\/products\/value-collection-33708-31-2-hex-socket-cap-screw-7-8-9","provider":"Voomi Supply","version":"1.0","type":"link"}
