This is a partially threaded fastener conforming to ASME B18.2.1, the standard governing inch-series hex cap screws for general industrial and mechanical assembly applications. Grade 5 steel provides a reliable strength rating for moderate-load fastening tasks, and the zinc plating adds a basic level of corrosion resistance suitable for interior and light exterior use. Licensed tradespeople and maintenance technicians working on HVAC equipment frames, electrical panel enclosures, plumbing fixture brackets, and similar structural assemblies commonly use this fastener type.\u003c\/p\u003e\n\u003cp\u003eThis screw fits standard 5\/16-18 UNC tapped holes or through-hole assemblies where a hex head drive is required. The partial threading allows the shank to act as a shoulder or grip zone, making it appropriate for clamping applications where the unthreaded shank spans a clearance hole before engaging a tapped member. It is well suited for light structural connections in equipment housings, mounting plates, access panels, and general mechanical assemblies encountered in trade service work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread size with 5-inch length under head for deep-reach fastening\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction for moderate tensile strength in general mechanical applications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for basic corrosion resistance in interior and sheltered environments\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank per ASME B18.2.1 for clamping through clearance holes\u003c\/li\u003e\n  \u003cli\u003eInch measurement system with UNC thread standard for wide tool and hardware compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use in any 5\/16-18 UNC tapped hole or nut application requiring a partially threaded fastener per ASME B18.2.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation does not require a licensed trade but is commonly performed by HVAC technicians, electricians, and plumbers during equipment mounting and bracket assembly work. Use a 1\/2-inch wrench or socket to drive this hex head fastener to the appropriate torque for the assembly material and load requirements. Ensure the mating tapped hole or nut is clean and free of debris before installation. Do not substitute Grade 5 hardware in applications specifying Grade 8 or metric property class fasteners.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: D30042\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694118109490,"sku":"D30042","price":50.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/de30a95fedd69be4f48add463872bb4a.jpg?v=1788320492","url":"https:\/\/voomisupply.com\/products\/value-collection-d30042-hex-head-cap-screw-5-16-18-x-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
