This fastener features a unified national coarse (UNC) thread form and a bright, uncoated finish. The flat head profile sits flush with the mating surface when fully driven, making it well suited for applications where a low-profile or countersunk finish is required. Grade 316 stainless steel provides strong resistance to corrosion and oxidation, including in chloride-rich and marine environments. Installed by maintenance technicians, pipefitters, electricians, and general contractors across a wide range of industries.\u003c\/p\u003e\n\u003cp\u003eThis machine screw is used in applications demanding corrosion resistance and a clean countersunk appearance. Typical install scenarios include panel mounting, equipment enclosures, marine fixtures, food-service equipment, and coastal or chemical-exposure environments where standard carbon steel fasteners would corrode prematurely. The slotted drive accepts a standard flat-blade screwdriver, making it accessible with basic hand tools. Overall length is 1-1\/2 inches with length under head also measuring 1-1\/2 inches, indicating measurement is taken from the top of the flat head.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 316 stainless steel construction for superior corrosion resistance in harsh and marine environments\u003c\/li\u003e\n  \u003cli\u003eFlat head profile for flush or countersunk installations\u003c\/li\u003e\n  \u003cli\u003eSlotted drive compatible with standard flat-blade screwdrivers\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread for broad compatibility with standard tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no surface treatment that could degrade in chemical or saltwater exposure\u003c\/li\u003e\n  \u003cli\u003eNo washer — clean, low-profile seating against the workpiece surface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/4-20 UNC tapped holes and compatible with 1\/4-20 hex nuts, locknuts, and threaded inserts.

Use a properly sized flat-blade screwdriver to avoid camming out the slotted drive. Drill and countersink the mating material to the appropriate angle — flat head machine screws typically require an 82-degree countersink, though always verify against the applicable engineering specification for the assembly. Follow applicable codes and torque guidance from the equipment manufacturer or structural engineer of record.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 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\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/2 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\u003eWasher Style\u003c\/strong\u003e: Without Washer\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: 0.008 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: R56001704\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691857543474,"sku":"R56001704","price":3581.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30c40908d18b45674cd31527edf64aac.jpg?v=1788290522","url":"https:\/\/voomisupply.com\/products\/value-collection-r56001704-machine-screw-1-4-20-x-1-1-2-in-ss-316","provider":"Voomi Supply","version":"1.0","type":"link"}
