This Type F point style features a tapered end with cutting edges that displace material as the fastener is driven, eliminating the need for a pre-tapped hole. Built from Grade 2 steel with a zinc-plated finish, it delivers solid corrosion resistance for general-purpose indoor and light industrial applications. The 3\/4-inch length under head suits a range of sheet metal, structural, and fabrication tasks. Sold in a pack of 50, this fastener is a standard choice for production assembly, maintenance, and repair work.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in light to medium fabrication scenarios where threading into unthreaded base material is required. The hex head drive allows for high torque application using a nut driver, socket wrench, or hex bit, making it practical on production lines and service calls alike. Typical applications include metal-to-metal fastening in HVAC equipment panels, electrical enclosures, light structural assemblies, and general sheet metal work. The zinc plating provides a baseline level of corrosion protection appropriate for dry or lightly humid indoor environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType F point cuts threads directly into pre-drilled holes, no tapping required\u003c\/li\u003e\n  \u003cli\u003eHex head drive accepts standard nut drivers, sockets, and hex bits for high-torque installation\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction provides adequate strength for general-purpose fastening applications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers corrosion resistance suitable for dry indoor environments\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread standard for broad compatibility with standard tooling and hardware\u003c\/li\u003e\n  \u003cli\u003ePack of 50 supports production, service, and maintenance workflow efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose thread cutting fastener for use in metal panels, enclosures, and light structural assemblies where a 1\/4-20 UNC thread is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed with a properly sized nut driver, socket, or hex bit to avoid fastener damage. Ensure the base material is pre-drilled to the correct pilot hole diameter for a 1\/4-20 Type F thread cutting screw before driving. Do not overtorque, as Grade 2 steel has lower tensile strength than higher-grade fasteners. Follow applicable mechanical and structural codes for the assembly type being fastened.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Type F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 31839\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695851471154,"sku":"31839","price":17.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47f80a159784ce0981e55bdf7fe7ae93.jpg?v=1788338786","url":"https:\/\/voomisupply.com\/products\/value-collection-31839-1-4-20-unc-hex-thread-cutting-screw-50pk","provider":"Voomi Supply","version":"1.0","type":"link"}
