Sized at 5\/16-18 UNC with a 3\/4 inch length under head, it is driven with a 1\/4 inch hex key. The fastener is manufactured from 18-8 stainless steel, providing solid corrosion resistance suitable for wet, outdoor, or chemically exposed environments. This screw is a standard choice for equipment assembly, bracket mounting, and maintenance tasks across HVAC, plumbing, electrical, and general mechanical trades.\u003c\/p\u003e\n\u003cp\u003eThis screw suits residential and light commercial applications where a compact, corrosion-resistant fastener is required. It is commonly installed in control panel assemblies, equipment housings, pipe supports, and structural brackets. The 5\/16-18 UNC thread pattern is a widely used coarse thread, compatible with standard UNC tapped holes and hex-drive tooling found in most trade toolkits. Maintenance technicians and installers across multiple trades rely on this fastener for routine equipment service and new installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch length under head suits medium-depth fastening applications\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank maximizes thread engagement across the full grip length\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction resists corrosion in wet and outdoor environments\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch hex socket drive for use with standard hex keys and socket drivers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 UNC hex socket cap screw for use in any application requiring a fully threaded stainless steel fastener driven by a 1\/4 inch hex key.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 1\/4 inch hex key or hex bit driver. Ensure the mating tapped hole is clean and free of debris before installation. Do not overtighten stainless steel fasteners, as galling can occur — apply an appropriate anti-seize compound when fastening into stainless or aluminum threads. 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: 5\/16-18 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 1\/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\u003eWeight\u003c\/strong\u003e: 0.025 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 198784\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699920372018,"sku":"198784","price":9696.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a700b8c62c2d170416df814f9184002.jpg?v=1788383431","url":"https:\/\/voomisupply.com\/products\/value-collection-198784-hex-socket-cap-screw-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
