8-Piece 3/8" Drive SAE Universal Impact Extension Socket Set | 1/3 Drawer EVA Foam

    DETAILS

    This set provides eight 3/8" drive SAE universal impact extension sockets in 6-point geometry, spanning 5/16" through 3/4". Each socket combines a 12" extension shank with an integrated universal joint, allowing fasteners to be reached at an angle through suspension components, engine bays, and framework where a straight socket and separate extension cannot be aligned. Chrome molybdenum steel construction handles impact-driver torque, and a black phosphate finish resists corrosion from moisture and shop fluids.

    The set is housed in a CNC-cut 2-tone EVA foam insert sized for a 1/3 drawer position in the 26" BoxoUSA system. Each socket sits in a dedicated pocket, so the full range is visible at a glance and any missing tool is identified before the drawer closes.

        KEY FEATURES

        • Integrated Universal Joint: Each socket articulates at the head, allowing engagement of fasteners offset from the tool path without stacking separate u-joints and extensions that introduce play and drop points.
        • 12" Extension Length: Extended shank reaches recessed and obstructed fasteners through wheel wells, subframes, and engine bays while keeping the drive end clear of hot or sharp components.
        • Chrome Molybdenum Steel Construction: Impact-rated alloy absorbs the shock loading of pneumatic and cordless impact wrenches without cracking or deforming under repeated cycles.
        • Black Phosphate Finish: Non-reflective corrosion-resistant coating protects the tool surface in humid shop environments and under exposure to cleaners, oils, and coolants.
        • 6-Point Standard Geometry: Full flank contact across 5/16" to 3/4" reduces fastener rounding on high-torque and corroded hardware where 12-point contact would slip.
        • CNC-Cut 2-Tone EVA Foam Insert: Precision-cut pockets hold each socket in a fixed position, provide immediate visual tool accountability against the contrasting base layer, and resist shop chemicals and fluids.
        • 1/3 Drawer Format: Sized to the 26" BoxoUSA drawer system so the set integrates with rolling cabinets and workstations alongside other foam inserts without wasted drawer space.
