This screw follows Unified National Coarse (UNC) thread standards and is sized for applications where a flush or countersunk fastening profile is required. The flat head geometry allows the fastener to sit flush with or below the mating surface when installed in a properly countersunk hole. The 18-8 stainless steel construction provides corrosion resistance suitable for general-purpose industrial, mechanical, and maintenance applications. Electricians, HVAC technicians, plumbers, and general maintenance trades commonly use fasteners of this type for panel assembly, equipment mounting, and fixture attachment.\u003c\/p\u003e\n\u003cp\u003eThis machine screw is suited for light-duty fastening tasks across residential and commercial service work. Typical applications include securing electrical enclosure covers, attaching brackets, and fastening hardware components where a low-profile head is needed. The 1\/4-20 UNC thread is one of the most widely used coarse thread standards in North American trade work, making this screw compatible with a broad range of tapped holes, hex nuts, and threaded inserts of the same specification. The slotted drive accepts a standard flat-blade screwdriver, keeping installation straightforward without requiring specialty tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC coarse thread for broad compatibility with standard tapped hardware\u003c\/li\u003e\n  \u003cli\u003eFlat head profile seats flush or countersunk into mating surfaces\u003c\/li\u003e\n  \u003cli\u003eSlotted drive accommodates standard flat-blade screwdrivers\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction resists corrosion in general service environments\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish with no plating that could interfere with electrical grounding contact\u003c\/li\u003e\n  \u003cli\u003eOverall length and length under head both measure 1\/2 inch\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any application requiring a 1\/4-20 UNC flat head slotted machine screw with a 1\/2 inch overall length.

When used in countersunk applications, verify the mating material is properly countersunk to the correct angle to achieve full flush seating. For electrical panel or enclosure use, follow applicable NEC requirements for fastener material and grounding continuity. De-energize any electrical equipment before accessing internal hardware.\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\u003eOverall Length\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1\/2 inch\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\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: 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: 0.01 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: 92586\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692119654706,"sku":"92586","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e90466da886ab262e46bac8eacca3ebe.jpg?v=1788293364","url":"https:\/\/voomisupply.com\/products\/value-collection-92586-1-4-20-x-1-2-in-flat-head-machine-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
