At 2.75 inches in length measured under the head, this fastener is sized for structural and mechanical assembly tasks where corrosion resistance is a priority. Grade 316 stainless steel provides superior resistance to chlorides, salt spray, and chemical exposure compared to standard 304 alloy, making it a dependable choice where environmental exposure is a factor. Installers working in corrosive or marine-adjacent environments will recognize this alloy as the appropriate spec for those conditions.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in mechanical assemblies, equipment mounting, and structural fastening applications across industrial, commercial, and marine environments. The flat head profile allows the fastener to sit flush with or below the mating surface when installed into a countersunk hole, making it appropriate for applications where a low-profile finish is required. The slotted drive is compatible with standard flat-blade screwdrivers and slotted power bits commonly found in any trade toolkit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 316 stainless steel construction for high corrosion resistance in chloride and marine environments\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread size for use with standard 3\/8-16 nuts, inserts, and tapped holes\u003c\/li\u003e\n  \u003cli\u003eFlat head profile designed for countersunk installations requiring a flush or recessed surface finish\u003c\/li\u003e\n  \u003cli\u003eSlotted drive compatible with flat-blade screwdrivers and standard slotted bits\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish preserves the natural corrosion resistance of the 316 alloy without added coatings\u003c\/li\u003e\n  \u003cli\u003eLength measured under head at 2.75 inches for accurate fitment planning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8-16 UNC machine screw for use in any application requiring that thread pitch, a flat countersunk head, and Grade 316 stainless steel material compliance.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by maintenance technicians, millwrights, or trade professionals using a flat-blade screwdriver or compatible power driver bit. Ensure the mating hole is properly tapped to 3\/8-16 UNC or a matching nut is used to avoid cross-threading. For countersunk installations, verify the receiving surface is machined or drilled to match the flat head angle before driving the fastener to final torque. Do not use impact drivers without a torque-limiting clutch, as over-torquing stainless steel fasteners can cause galling or thread seizure.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Slotted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2.75 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: 316\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\/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: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161504\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: R52001401\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721242149170,"sku":"R52001401","price":25.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69fe3a46891c9b845f056a02b252b316_bb2bef73-f706-46b2-9bc2-09a3bcf44aa1.jpg?v=1788575233","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001401-machine-screw-3-8-16-flat-head","provider":"Voomi Supply","version":"1.0","type":"link"}
