The Diablo 1/4 in. x 6 in. Magnetic Nut Driver (model DNTSXL14B) is built for pros and serious DIYers. This is a magnetic nut driver for drills and impact drivers, designed for hex-head nuts, bolts and self-tapping fasteners.

Self-drilling hex-head screws are the standard fastener on metal roofing, siding, steel studs, ductwork and HVAC equipment. A 1/4 in. nut driver that holds the screw and stands up to an impact driver is a daily-use tool for those trades.

The 6 in. length gives you reach into recessed fasteners, past flanges and into tight equipment cabinets without an extension.

A high-strength permanent magnet holds the fastener in the socket to cut down on wobble and dropped hardware. The Increased Torsion Zone and Impact Strong construction absorb impact torque, and laser-engraved, color-coded markings make it easy to grab the right size.

This is the bulk version, sold as a single nut driver without retail packaging.

Ideal for roofers, siding and metal building crews, HVAC techs, electricians and anyone driving hex-head screws all day.

The Diablo 1/4 in. x 6 in. Magnetic Nut Driver: The Nut Driver That Holds On

A strong magnet and an impact-rated shaft are what matter in a nut driver, and this one has both.

• Who it's for: Roofing, siding, HVAC and metal building crews driving hex-head screws.
• Why it stands out: Permanent magnet retention plus Impact Strong construction and a torsion zone.
• Worth knowing: Keep the socket clean of metal shavings. Chips stuck to the magnet are what make hex screws sit crooked.
