• 6-Point Box End: Equipped with Proto's TorquePlus™ system, the box end makes contact on the flat surfaces of hex fasteners rather than the corners. This design minimizes slipping and allows you to apply up to 15% more torque safely.
• Anti-Slip Design (ASD): The open-end jaw features advanced locking geometry to prevent slipping while working on fasteners.
• Full Polish Chrome: Offers premium resistance against rust, corrosion, and chemicals. The mirror-like finish makes grease and grime quick to wipe away.
• Ergonomic Clearance: The box head is angled at a 15-degree offset, keeping your knuckles clear of surrounding obstructions or flush surfaces.
