Proto 1/2" Drive 6 Piece Extra Long Hex Bit Set J5441-6XL-SBD
Details
Proto's professional-grade 1/2-inch drive 6-piece extra-long hex bit socket set engineered for heavy-duty industrial applications requiring maximum reach and high torque. Forged from high-strength alloy steel, these sockets feature a full polish chrome finish for superior corrosion resistance and effortless maintenance in harsh environments. The extra-long bit profile is specifically designed to access deep-seated fasteners in recessed mechanical assemblies where standard-length tools cannot reach. The set includes a curated fractional range from 1/4 inch to 5/8 inch, all precision-machined for an exact, non-slip fit that prevents fastener rounding and head damage. For convenience and organization, the bits are provided on a socket bar with secure clips, ensuring rapid tool identification and secure storage. This set is a critical solution for technicians working on heavy machinery, structural assemblies, and large-scale mechanical repairs. The shipping weight for this 6-piece set is approximately 3.40 lbs.
