#2 SQUARE INSERT BIT 25PK

Drive square-drive screws with maximum torque transfer and zero cam-out using the Makita A-99770 ImpactX #2 Square Recess 1" Insert Bit 25-Pack. Purpose-built for professional contractors utilizing high-torque cordless impact drivers, the ImpactX series eliminates the brittle snapping typical of standard screwdriving bits. Each bit features a precision CNC-machined SQ2 tip that seats deeply and securely into square-drive fasteners, minimizing wobble and stripping under heavy driving loads. Manufactured from performance-optimized S2 tool steel and refined via a calibrated heat-treatment process, these insert bits absorb severe rotational shock waves without fracturing. An industrial manganese phosphate finish provides advanced resistance to moisture and corrosion, making this contractor 25-pack an essential choice for deck building, subflooring, framing, and timber fabrication.

Key Features:

• Precision-Machined SQ2 Tip: CNC-machined square recess tip provides a full-contact fit to prevent cam-out and stripped fastener heads.

• Impact-Rated S2 Tool Steel: Formulated with optimal elasticity to flex under extreme torque loads rather than snap.

• Calibrated Heat Treatment: Multi-stage tempering delivers balanced core toughness and high surface hardness for extended bit life.

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

• Contractor 25-Pack: Bulk pack ensures continuous jobsite productivity and lower cost per bit for high-volume fastening.

• Universal 1/4" Hex Shank: Designed for use with standard magnetic bit holders in cordless impact drivers and driver-drills.

• Versatile Heavy-Duty Applications: Ideal for timber framing, structural decking, subfloor installation, and general carpentry.
