Manufactured from Grade 316 stainless steel, this fastener delivers strong corrosion resistance in wet, chemical, and marine environments where standard 18-8 hardware would degrade. The uncoated finish maintains precise thread tolerances right out of the box. Tradespeople working in HVAC equipment panels, plumbing fixture assemblies, electrical enclosures, and pool equipment installations will find this fastener well suited to applications that see moisture, chlorine, or aggressive cleaning agents.\u003c\/p\u003e\n\u003cp\u003eThis screw is commonly used in residential and light commercial applications wherever a fine-thread, corrosion-resistant fastener is required. Typical install scenarios include mounting components inside HVAC air handlers, securing pool pump and filter hardware, and fastening electrical panel sub-assemblies in humid or outdoor locations. The fine 1\/4-28 UNF thread provides better vibration resistance and finer clamping adjustment compared to coarse-thread equivalents, making it a practical choice in metal-to-metal assemblies where thread stripping risk must be minimized.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 316 stainless steel construction for superior resistance to chlorides, salt spray, and corrosive chemicals\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank along the full 1\/2-inch length under head for maximum thread engagement in thin stock\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 UNF fine thread standard for improved vibration resistance and precise clamping control\u003c\/li\u003e\n  \u003cli\u003eUncoated finish preserves dimensional accuracy and avoids coating buildup in close-tolerance holes\u003c\/li\u003e\n  \u003cli\u003eStandard hex head drive accepts common 7\/16-inch wrenches and hex sockets found in every trade toolbox\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-28 UNF fully threaded hex head cap screw for use in any application requiring an inch-series fine-thread fastener in Grade 316 stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 7\/16-inch open-end, box, or socket wrench. Always power down or de-energize any equipment before accessing fastened panels or enclosures. Avoid mixing stainless steel fasteners with dissimilar metals in submerged or continuously wet assemblies to reduce galvanic corrosion risk. Hand-start threads carefully to prevent cross-threading, as fine UNF threads are more susceptible to galling on stainless steel — applying an appropriate anti-seize compound is standard practice.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF (Unified Fine)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\u003c\/strong\u003e: Fully 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: 316\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: 0.006 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: R88383484\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692729205042,"sku":"R88383484","price":1994.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a214b7d919e821738328f0636c690f80.jpg?v=1788301833","url":"https:\/\/voomisupply.com\/products\/value-collection-r88383484-hex-head-cap-screw-1-4-28","provider":"Voomi Supply","version":"1.0","type":"link"}
