Each screw measures 5\/16-18 x 1 inch, featuring a coarse thread pitch that seats quickly and holds securely in steel, cast iron, and similar hard substrates. Manufactured from heat treated steel, these fasteners meet the strength requirements of Grade 5 classification, making them suitable for moderate-load bolted connections. This item is sold as a 100-pack, stocked for service trucks, maintenance shops, and job-site use where consistent fastener supply is essential.\u003c\/p\u003e\n\u003cp\u003eThese hex cap screws are used across a broad range of trade applications including HVAC equipment assembly, pipe support and strut mounting, electrical enclosure hardware, and general mechanical maintenance. The 5\/16-18 coarse thread is one of the most common sizes in light-to-medium duty bolted joints and is compatible with standard 5\/16-18 hex nuts and flat washers. Installers working in HVAC, plumbing, and electrical disciplines will find this size relevant for equipment mounting brackets, access panels, and structural supports.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 5 heat treated steel construction for moderate-load fastening duty\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 coarse thread for fast engagement and broad nut compatibility\u003c\/li\u003e\n  \u003cli\u003e1 inch grip length suits standard bracket and panel thicknesses\u003c\/li\u003e\n  \u003cli\u003eHex cap drive compatible with standard 1\/2-inch wrenches and sockets\u003c\/li\u003e\n  \u003cli\u003e100-pack quantity reduces restocking frequency on active job sites\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 coarse thread Grade 5 hex cap screw compatible with any 5\/16-18 hex nut, coupling nut, or tapped hole conforming to unified coarse thread (UNC) standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is appropriate for any qualified trade technician performing mechanical assembly or equipment mounting. Always verify the mating thread specification before installation to confirm UNC 5\/16-18 compatibility. Use a calibrated torque wrench when the joint design specifies a torque value; do not rely on feel alone for structural connections. De-energize equipment and relieve system pressure before removing or replacing fasteners on live mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Cap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Grade 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Heat Treated Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 29 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: HILLMAN FASTENERS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 200069\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILLMAN","offers":[{"title":"Default Title","offer_id":51562923196722,"sku":"200069","price":209.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd3ee46a607851a26b4c6ab3dbfcb801_65389513-d719-4707-9c45-c1406ac60e3b.jpg?v=1786486741","url":"https:\/\/voomisupply.com\/products\/hillman-fasteners-200069-hex-cap-screw-5-16-18x1-grade-5-100pk","provider":"Voomi Supply","version":"1.0","type":"link"}
