3/8IN (1-3/4IN) MAG NUTSETTER

Fasten 3/8" hex-head screws and self-tapping hardware with precision and durability using the Makita A-97667 ImpactX 3/8" x 1-3/4" Magnetic Nutsetter. Built to withstand the continuous rotational shock of high-torque cordless impact drivers, the ImpactX series eliminates the brittle fractures and early wear typical of standard fastening accessories. Manufactured from performance-optimized S2 tool steel and refined with a calibrated heat-treatment cycle, this compact nut driver delivers balanced torsional flex under heavy loads. The precision-machined lobular socket drives against fastener flats rather than sharp corners to prevent stripping and head round-off, while flat edges at the hex mouth provide flush contact with flanged screws. A powerful internal magnet ensures reliable one-handed screw starting, shielded by an industrial manganese phosphate surface that guards against corrosion and jobsite moisture.

Key Features:

• Heavy-Duty Magnetic Retention: High-strength internal magnet holds fasteners firmly for effortless one-handed starting and overhead driving.

• Lobular Drive Profile: Engages the flat sides of hex hardware to reduce stripping, slipping, and corner rounding under high torque.

• Flanged Fastener Fit: Precision-machined flat edges at the socket opening ensure complete contact with flanged hex-head screws.

• Impact-Rated S2 Tool Steel: Formulated with high ductility to absorb severe rotational shock waves without snapping.

• Calibrated Heat Treatment: Precision tempering process delivers balanced core elasticity and long-lasting edge durability.

• Manganese Phosphate Finish: Advanced anti-corrosion barrier protects against rust and harsh environmental wear.

• Compact 1-3/4" Reach: Compact profile allows easy maneuverability in tight corners, cabinetry, and structural framing joints.

• Universal 1/4" Hex Fitment: Standard 1/4" hex shank locks securely into quick-release impact driver chucks and bit holders.
