Sized at 3\/8-16 thread with a 9.5-inch length under head, this fastener is manufactured from 18-8 stainless steel and left uncoated, making it well-suited for environments where rust resistance and material compatibility matter. The UNC (Unified National Coarse) thread form seats reliably in standard tapped holes and mating nuts. Partial threading along the shank allows for shoulder-like clamping behavior in bolted joint applications.\u003c\/p\u003e\n\u003cp\u003eThis cap screw fits into general mechanical assembly, structural fastening, and equipment fabrication scenarios where stainless steel hardware is specified. The 3\/8-16 UNC thread is a common size across HVAC, plumbing, pool equipment, and light structural work, making this screw a practical stock item for service technicians and maintenance crews working across multiple trade disciplines. The 9.5-inch length under head accommodates thicker assemblies or applications requiring extended bolt engagement.\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 or outdoor environments\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows controlled clamping and shear-load distribution\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread is a standard size compatible with common tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains dimensional accuracy without plating buildup\u003c\/li\u003e\n  \u003cli\u003e9.5-inch length under head suits deep-reach or thick-stack fastening applications\u003c\/li\u003e\n  \u003cli\u003eInch measurement system for compatibility with standard imperial tooling and hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-system hex head cap screw suitable for use with 3\/8-16 UNC tapped holes and mating hex nuts across general mechanical, structural, and trade equipment assembly applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified technician or mechanic using a standard 9\/16-inch hex wrench or socket sized for a 3\/8-inch hex head cap screw. Ensure the mating thread or nut is also 3\/8-16 UNC before installation to avoid cross-threading. De-energize or depressurize any system before fastener replacement or removal. Stainless steel fasteners can be prone to galling during installation — applying an appropriate anti-seize compound to the threads is a common field practice.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 9.5 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\u003eThreading\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\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: 0.5 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: 2\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: R57001228\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714605580594,"sku":"R57001228","price":1770.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/94218d21533edc8d86d97c4d4fdf935f.jpg?v=1788503797","url":"https:\/\/voomisupply.com\/products\/value-collection-r57001228-hex-head-cap-screw-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
