The partially threaded shank follows UNC (Unified National Coarse) thread standards, making it suitable for general-purpose fastening in corrosive or wet environments where carbon steel fasteners would be unsuitable. This screw is driven with a standard hex wrench or socket and is commonly specified by millwrights, maintenance mechanics, plumbers, and field service technicians for equipment assembly, structural connections, and process piping hardware.\u003c\/p\u003e\n\u003cp\u003eThis fastener is well-suited for commercial and industrial applications where corrosion resistance is a primary concern, including food processing equipment, marine hardware, pool and water treatment installations, and chemical handling systems. The 18-8 stainless steel grade offers a reliable balance of strength and corrosion resistance for most non-marine-grade fastening applications. The partial threading allows the unthreaded shank to pass cleanly through clearance holes before engaging the threaded bore or nut.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9\/16-12 UNC thread — coarse pitch for fast engagement and strong pull-out resistance\u003c\/li\u003e\n  \u003cli\u003e3-1\/2 inches length under head — partially threaded shank for accurate shear-load positioning\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction — resists oxidation, rust, and mild chemical exposure\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — no plating or coating to flake, contaminate, or introduce galvanic incompatibility concerns\u003c\/li\u003e\n  \u003cli\u003eInch measurement system — direct fit for standard UNC tapped holes and hex nuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard UNC 9\/16-12 tapped holes and with 9\/16-12 hex nuts or coupling nuts.

Avoid mixing stainless steel fasteners with dissimilar metals in wet environments to minimize galvanic corrosion risk. Apply an anti-seize compound rated for stainless steel threads before installation to prevent galling, which is a common failure mode with stainless fasteners under torque. De-energize or depressurize the assembly being serviced before removing or replacing structural fasteners.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-12\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\u003eThread Standard\u003c\/strong\u003e: UNC (Unified National Coarse)\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: 0.2 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: R57001259\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693872152882,"sku":"R57001259","price":2319.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac42683db06a78c32c0e91c7742db730.jpg?v=1788318348","url":"https:\/\/voomisupply.com\/products\/value-collection-r57001259-hex-cap-screw-9-16-12-x-3-1-2-in-18-8-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
