The 3-inch shaft is hollow, allowing it to seat fully over long bolts without bottoming out. A magnetic tip holds fasteners in place during placement and removal, reducing dropped hardware in tight spaces. The driver ships as a two-piece set covering the two most common HVAC fastener sizes: 1\/4 inch and 5\/16 inch. Chrome-vanadium steel construction provides durability under repeated daily use in the field.\u003c\/p\u003e\n\u003cp\u003eThis nut driver set is suited for residential and light commercial HVAC service work, including panel removal, blower compartment access, and equipment installation. The color-coded inserts — red and yellow — allow quick size identification when both drivers are on a belt or in a bag. Wrench flats on the body let technicians apply additional torque with an open-end wrench when hand torque is insufficient. The slip-resistant grip supports controlled driving in awkward positions or overhead installs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMagnetic tip securely holds fasteners during placement and removal\u003c\/li\u003e\n  \u003cli\u003eHollow 3-inch shaft accommodates long bolts without obstruction\u003c\/li\u003e\n  \u003cli\u003eColor-coded inserts for fast size identification: red and yellow\u003c\/li\u003e\n  \u003cli\u003eWrench flats on body allow extra torque with an open-end wrench\u003c\/li\u003e\n  \u003cli\u003eSlip-resistant grip for controlled driving in awkward positions\u003c\/li\u003e\n  \u003cli\u003eChrome-vanadium steel construction for field durability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/4-inch and 5\/16-inch hex-head fasteners commonly found in HVAC equipment panels, ductwork, and electrical enclosures.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eHVAC technicians install and service this tool without electrical lockout requirements, but standard service precautions apply when working near energized equipment. Use the wrench flats with an appropriately sized open-end wrench only when additional torque is needed to avoid fastener damage. Inspect the magnetic tip periodically to ensure it retains adequate holding strength, particularly after prolonged exposure to metal shavings or debris.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Sizes Included\u003c\/strong\u003e: 1\/4 inch, 5\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Type\u003c\/strong\u003e: Hollow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Type\u003c\/strong\u003e: Magnetic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Chrome-vanadium steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColors\u003c\/strong\u003e: Red and Yellow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each (set of 2)\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: HILMOR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1839066\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILMOR","offers":[{"title":"Default Title","offer_id":51383714971954,"sku":"1839066","price":45.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312674293.webp?v=1782605286","url":"https:\/\/voomisupply.com\/products\/hilmor-1839066-magnetic-nut-driver-3-inch-shaft","provider":"Voomi Supply","version":"1.0","type":"link"}
