• 6-Point Box End: Unlike standard 12-point variations, the 6-point configuration offers maximum surface contact on hex fasteners. This configuration drastically reduces the risk of slipping or damaging rusted and soft-metal nuts and bolts.
• Anti-Slip Design (ASD): The open end features Proto's proprietary anti-slip geometric indexing, which delivers superior grip and forces torque away from fastener corners.
• Full Polish Chrome Finish: This provides heavy corrosion resistance and an easy-to-clean surface after greasy jobs.
