It features a UNC (Unified National Coarse) thread form and an overall length of 1-1\/2 inches with a bright, uncoated finish. Grade 316 stainless steel provides strong resistance to corrosion and chloride exposure, making this fastener well suited for wet, marine, chemical, or outdoor environments. The flat head profile sits flush with the mating surface when fully driven. This screw is installed by machinists, maintenance mechanics, and general tradespeople in applications where corrosion resistance and a flush finish are required.\u003c\/p\u003e\n\u003cp\u003eThis machine screw is used in light to medium-duty mechanical assemblies, equipment enclosures, brackets, and fixtures where a countersunk flat head is specified. The slotted drive accepts a standard flat-blade screwdriver. Grade 316 stainless steel is a common specification in food service, marine, and chemical processing environments where standard 18-8 stainless may not provide adequate corrosion resistance. The UNC thread form is the most widely used inch-standard thread in North American mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 316 stainless steel construction for superior corrosion and chloride resistance\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread for compatibility with standard inch-series tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003eFlat head profile sits flush with the work surface when properly countersunk\u003c\/li\u003e\n  \u003cli\u003eSlotted drive accepts standard flat-blade screwdrivers\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no plating to chip, flake, or introduce contamination\u003c\/li\u003e\n  \u003cli\u003eOverall length of 1-1\/2 inches with full-length thread under the head\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/2-13 UNC tapped holes or with matching 1\/2-13 hex nuts and flat washers.

The mating hole should be properly countersunk to the appropriate flat head angle before driving the screw flush. Do not overtighten stainless steel fasteners, as galling can occur — apply anti-seize compound when torque requirements are critical. Ensure threads are clean and free of debris before assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 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: 0.04 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: R56001756\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717995364658,"sku":"R56001756","price":8640.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/551848cb40aada78fbd277e766980b56.jpg?v=1788548221","url":"https:\/\/voomisupply.com\/products\/value-collection-r56001756-machine-screw-1-2-13-flat-head","provider":"Voomi Supply","version":"1.0","type":"link"}
