Black Decker IWAF346516 Impact Nut Driver 5/16in 6in

Product Description

The BLACK DECKER IWAF346516 is a 6-inch magnetic impact nut driver engineered for use with impact tools in demanding trade applications. The 5/16-inch lobular drive geometry engages the flat sides of the fastener rather than the corners, which preserves fastener shape, reduces stripping, and cuts breakage under high-torque impact loads. A black oxide finish adds corrosion resistance to extend service life in the field. Licensed electricians, HVAC technicians, plumbers, and general contractors who rely on impact drivers daily will find this driver holds up to continuous professional use.

This nut driver is suited for residential and light commercial work wherever a 5/16-inch fastener is driven with an impact tool. Common applications include electrical panel work, equipment mounting, ductwork fasteners, and structural hardware. The extended 6-inch length provides reach in confined spaces where a standard-length driver cannot clear surrounding components. The lobular geometry also leaves more clearance at fastener corners, which is useful when working with painted or coated hardware where buildup at the corners can otherwise cause bit slippage.

Key Features

• Lobular drive design engages fastener sides rather than corners, reducing stripping and fastener damage
• Built-in magnet retains 5/16-inch nuts and hardware during placement
• 6-inch overall length extends reach into recessed or obstructed mounting areas
• Black oxide finish resists corrosion for extended tool life in field conditions
• Engineered for compatibility with standard impact drivers and impact wrenches
• Increased corner clearance helps engage fasteners with paint or debris buildup

Compatibility

Designed for use with standard 1/4-inch hex shank impact drivers and impact-rated power tools that drive 5/16-inch fasteners.

Installation Notes

Installation of this nut driver requires no special tools beyond a compatible 1/4-inch hex shank impact driver or impact wrench. Ensure the tool is powered off or the battery is removed before inserting or swapping driver bits. Verify the fastener size matches the 5/16-inch drive before applying torque to avoid fastener or bit damage. Follow applicable NEC or other trade code requirements for the specific fastening application being performed.
