Manufactured from 18-8 stainless steel, this fastener features a 1\/2-20 UNF (Unified National Fine) thread and a length under head of 1-1\/4 inches. The 3\/4-inch hex drive accepts standard hex wrenches and sockets for reliable installation torque. Its fine-thread pitch provides stronger thread engagement and better resistance to loosening under vibration compared to coarse-thread equivalents. This screw is suited for maintenance, fabrication, and equipment assembly work across HVAC, plumbing, electrical, and general mechanical trades.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used in applications where stainless steel is specified for its corrosion resistance — including outdoor equipment mounting, wet environments, pool and spa mechanical assemblies, and coastal installations. The 1\/2-20 UNF thread is a standard inch-series fine thread, compatible with matching UNF nuts and tapped holes. This item is sold individually, with a minimum order quantity of 50 pieces, making it appropriate for shop stock, service van inventory, or project-specific procurement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-8 stainless steel construction resists rust and corrosion in wet or outdoor environments\u003c\/li\u003e\n  \u003cli\u003e1\/2-20 UNF fine-thread pitch for strong thread engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch length under head for standard fastening depth requirements\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch hex drive compatible with common wrenches and sockets\u003c\/li\u003e\n  \u003cli\u003eInch measurement system, UNF thread standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series UNF hex head cap screw for use in any application requiring a 1\/2-20 threaded fastener in 18-8 stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 3\/4-inch open-end wrench, box wrench, or socket. Ensure the mating nut or tapped hole is also a 1\/2-20 UNF thread before installation. In stainless steel fastener applications, apply an anti-seize compound to the threads to prevent galling during tightening. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF (Unified National Fine)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Drive Size\u003c\/strong\u003e: 3\/4 inches\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 209843\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698600673586,"sku":"209843","price":9831.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9d8d3386f7a20a07cd7578e0818e8495.jpg?v=1788365289","url":"https:\/\/voomisupply.com\/products\/value-collection-209843-hex-head-cap-screw-1-2-20-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
