Diablo Nut Setter DNTSL12 1/2 x 2 9/16 Inch Magnetic (1/4 Hex Shank Impact Strong MaxTorque Steel Extended Driver Bit Fastener HVAC Roofing)

Diablo DNTSL12 1/2-Inch x 2-9/16-Inch Impact Strong Extended Magnetic Nut Setter

The Diablo DNTSL12 is an extended 1/2-inch magnetic nut driver featuring an overall length of 2-9/16 inches and a 1/4-inch hex shank engineered for driving hex head sheet metal screws and lag fasteners in recessed spaces. Manufactured from heat-treated tool steel with a rust-resistant protective coating and an integrated MaxTorque shock-absorbing torsion zone, this impact-rated bit withstands peak torque pulses in high-output cordless drivers to deliver extended service life. Designed for HVAC technicians, metal roofers, and steel erectors fastening ductwork, metal panels, and deep framing brackets, its high-strength permanent magnet retains fasteners firmly to enable single-handed alignment and precise driving without wobble.

Best Used For:

• HVAC Recessed Ductwork & Sheet Metal Assembly: Driving 1/2-inch self-tapping screws into deep flanges, air handlers, and constrained furnace housings.
• Metal Roofing & Deep Panel Cladding: Securing corrugated metal panels, ridge caps, and tall trim profiles using magnetic fastener retention to eliminate dropped screws.
• Structural Steel & Framing Fastening: Sinking heavy-duty hex head bolts and self-drilling screws into steel studs, brackets, and joist hangers across hard-to-reach angles.

Key Performance & Safety Features

• MaxTorque Stress-Absorption Zone: Torsion core transfers rotational stress away from the socket recess to prevent driver cracking under peak impact loads.
• High-Strength Permanent Magnet: Integrated magnetic core firmly holds hex head screws to facilitate single-handed alignment and overhead driving.
• Impact Strong Heat-Treated Metallurgy: Custom heat-treated alloy steel construction resists mechanical fatigue and tip rounding under continuous use.
• Extended 2-9/16 Inch Shank Reach: Deep profile reaches past obstruction overhangs and into narrow channels inaccessible to short nut setters.
• Protective Corrosion Coating: Protective rust-resistant surface finish shields tool steel against moisture, chemical exposure, and jobsite wear.
• Laser-Etched Size Marking: High-visibility laser identification etching ensures fast tip recognition in high-density tool storage.

What's Included

• (1) Diablo 1/2" x 2-9/16" Impact Strong™ Extended Magnetic Nut Setter (DNTSL12)

Technical Specifications

Pro-Tip: Clean metal shavings from the magnetic socket periodically using a soft cloth or tape to ensure hex head fasteners sit completely flush against the drive shoulders for full torque transfer.
