Diablo Nut Setter DNTSS38 3/8 x 1 7/8 Inch Magnetic (1/4 Hex Shank Impact Strong MaxTorque S2 Steel Driver Bit Fastener HVAC Roofing)

Diablo DNTSS38 3/8-Inch x 1-7/8-Inch Impact Strong Magnetic Nut Setter

The Diablo DNTSS38 is a 3/8-inch magnetic nut driver with an overall length of 1-7/8 inches and a 1/4-inch hex shank engineered for driving hex head sheet metal screws and lag fasteners. Manufactured from modified S2 tool steel with a rust-resistant coating and an integrated MaxTorque shock-absorbing zone, this impact-rated driver withstands peak torque pulses in high-output cordless drivers to deliver up to 50X longer service life. Designed for HVAC technicians, metal roofers, and steel erectors fastening ductwork, metal panels, and framing brackets, its high-strength permanent magnet retains fasteners firmly to enable one-handed start and precise driving without wobble.

Best Used For:

• HVAC Ductwork & Sheet Metal Assembly: Driving 3/8-inch self-tapping screws through galvanized sheet metal and heating duct flanges.
• Metal Roofing & Cladding Installation: Securing metal roof panels, ridge caps, and perimeter trim 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.

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 Modified S2 Steel Metallurgy: Custom heat-treated alloy steel construction resists mechanical fatigue and tip rounding.
• 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.
• Universal 1/4-Inch Quick-Change Hex Shank: Fits securely into standard 1/4-inch quick-release chucks and standard drill driver jaws.

• (1) Diablo 3/8" x 1-7/8" Impact Strong™ Magnetic Nut Setter (DNTSS38)

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.
