The partially threaded shank provides a clamping zone that keeps mating components aligned without thread engagement along the full shaft length. At 0.25 pounds per unit, this fastener is suited for light structural, mechanical, and equipment assembly applications where corrosion resistance is required. Installation is performed with a standard hex wrench or socket driver. The UNC thread standard ensures broad compatibility with inch-system tapped holes and nuts.\u003c\/p\u003e\n\u003cp\u003eThis screw is commonly used in HVAC equipment assemblies, pump and motor mounting, plumbing fixture brackets, pool equipment enclosures, and general industrial maintenance where stainless steel is specified to resist moisture, chemicals, or outdoor exposure. The 5\/16-18 UNC thread is one of the most widely encountered sizes in trade equipment, making this a practical replacement or service fastener across a broad range of applications. The uncoated finish is appropriate where a bare stainless surface is acceptable or required by the application.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion resistance in wet, chemical, and outdoor environments\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows for precise clamping without full-length thread engagement\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread standard for compatibility with standard inch-system tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003e4-1\/4 inch length under head accommodates thicker stacks of material or deep-reach fastening scenarios\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains bare stainless surface properties without added plating or treatment\u003c\/li\u003e\n  \u003cli\u003eHex head drive accepts standard sockets, wrenches, and hex bit drivers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any application requiring a 5\/16-18 UNC hex head cap screw in 18-8 stainless steel with partial threading and a 4-1\/4 inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a mechanic, HVAC technician, plumber, or maintenance professional using a socket wrench or hex driver sized for a 5\/16-18 fastener. Always de-energize and lock out equipment before accessing fastened assemblies. Apply anti-seize compound if the fastener will be installed into a dissimilar metal to prevent galling, which is a known risk with stainless steel threads. Do not overtighten stainless steel fasteners, as the material is prone to thread galling when excessive torque is applied without lubrication.\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: 4-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Uncoated\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: 0.25 pounds\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: 50\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: R57001214\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694802796850,"sku":"R57001214","price":9150.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/233b7b24c460ab0a348ebe3ccc3a6af8.jpg?v=1788328547","url":"https:\/\/voomisupply.com\/products\/value-collection-r57001214-hex-head-cap-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
