SK Tools Fractional Socket SuperSet 40-Piece 3/8-Inch Drive 6 Point Metric (4090)
SK Hand Tools 4090 Fractional Socket SuperSet 40-Piece 3/8-Inch Drive 6 Point Metric is a comprehensive socket set designed for professional mechanics and DIY users. This set includes high visibility standard and deep impact sockets in both fractional and metric sizes, offering superior access and precise performance. Featuring SK's SureGrip® hex design, the sockets drive the side of the fastener rather than the corner, reducing rounding on rusted or damaged bolts. The nose-down design extends the taper for improved access over straight wall sockets, while black phosphate coating provides corrosion resistance for long-lasting durability. Laser-engraved markings every 120 degrees make each socket easy to read, and the entire set comes packaged in a durable molded plastic case for convenient storage and portability.
