It features a pan head profile, slotted drive, and a Type F point that cuts its own mating thread as it is driven, eliminating the need for a pre-tapped hole in many applications. Constructed from Grade 2 steel with a zinc-plated finish, it provides basic corrosion resistance suitable for indoor and controlled-environment use. The 3\/4-inch length under head accommodates moderate material stack-ups. This fastener is sold in a box of 100 pieces and is commonly handled by HVAC technicians, electricians, and sheet metal workers.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for light sheet metal fabrication, electrical enclosure assembly, control panel construction, and HVAC equipment housing work. The 4-40 UNC thread size is a standard fine-pitch designation common in small instrument panels, electrical junction boxes, and equipment chassis. The Type F point style makes it particularly useful where tapping a pilot hole separately is impractical. It is appropriate for residential and light commercial trade applications where a small-diameter, self-threading fastener is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType F thread cutting point drives into metal without a pre-tapped hole\u003c\/li\u003e\n  \u003cli\u003ePan head profile provides a low-profile bearing surface and wide clamping area\u003c\/li\u003e\n  \u003cli\u003eSlotted drive compatible with standard flat-blade screwdrivers and power drivers\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction for reliable tensile strength in light-duty fastening\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for basic corrosion protection in indoor environments\u003c\/li\u003e\n  \u003cli\u003eSold in a box of 100 pieces to support production and service work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 4-40 UNC thread cutting fastener suitable for light-gauge sheet metal, electrical enclosures, and equipment chassis assemblies where a Type F point self-threading screw is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by electricians, HVAC technicians, or sheet metal workers using a flat-blade screwdriver or appropriately sized power driver bit. Ensure the pilot hole diameter is sized correctly for the material thickness and hardness to achieve proper thread engagement without splitting or stripping. Do not overtorque small-diameter screws such as 4-40, as the reduced thread section is susceptible to shear under excessive torque. Follow applicable NEC or equipment manufacturer guidelines when fastening within electrical enclosures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Pan Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Slotted\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\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0007 pounds (per piece)\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: SPTCIF0-400750-100BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690244702514,"sku":"SPTCIF0-400750-100BX","price":1710.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f2f07920673cbbe8c4ea2703ff80dd31.jpg?v=1788267572","url":"https:\/\/voomisupply.com\/products\/value-collection-sptcif0-400750-100bx-4-40-unc-screw-100pk","provider":"Voomi Supply","version":"1.0","type":"link"}
