With a 0.25-inch (4 mm) hex drive and a 4-inch overall length, this bit reaches fasteners in recessed or hard-to-access locations that shorter bits cannot. It is sold as a single piece and suits electricians, HVAC technicians, plumbers, and general contractors who rely on power tools for high-volume fastening tasks. The bit is built to transfer torque efficiently from the driver to the fastener without slipping or stripping under repetitive use.\u003c\/p\u003e\n\u003cp\u003eThis bit is a practical fit for residential and commercial service work where a longer-reach hex-drive bit is needed. Typical applications include driving hex-head screws and bolts on equipment panels, enclosures, ductwork, and mechanical assemblies. It is compatible with standard power drivers and impact drivers that accept a 0.25-inch hex shank. Trades that frequently swap bits on the job will find the 4-inch length useful for panel and cabinet work where standard-length bits fall short.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.25-inch (4 mm) hex drive fits standard power drivers and impact drivers with a 0.25-inch hex chuck\u003c\/li\u003e\n  \u003cli\u003e4-inch overall length provides extended reach for recessed fasteners and deep-set applications\u003c\/li\u003e\n  \u003cli\u003eSingle-piece packaging makes it easy to stock as a replacement or add to an existing bit set\u003c\/li\u003e\n  \u003cli\u003eUNSPSC Code 27112814 for straightforward procurement and inventory classification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or add-on bit for power drivers and impact drivers accepting a standard 0.25-inch hex shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSeat the bit fully into the driver chuck before use to prevent cam-out or bit ejection under load. Verify the drive size matches the fastener head before applying power. Inspect the bit tip for wear or rounding after extended use, as a worn tip increases the risk of stripping fastener heads. No special tools or trade licensing is required, but follow applicable safety guidelines for power tool operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBit Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 0.25 inches (4 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches (102 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 1\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: 27112814\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: APEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: AM-4MM-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"APEX","offers":[{"title":"Default Title","offer_id":51542975676722,"sku":"AM-4MM-4","price":74.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eda7596c2241e767acbe593d7d297b0e.jpg?v=1785912851","url":"https:\/\/voomisupply.com\/products\/apex-am-4mm-4-power-screwdriver-bit-hex-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
