Key Features

• Optimized Torque Delivery: Features a heavy-duty TORQUE-SAVER™ design with an overbuilt joint and extension shaft, unique to Astro Pneumatic, to minimize torque loss. This design can deliver up to 30% more torque to fasteners at maximum angle and 20% more when used straight, compared to other universal extension sockets of similar length.
• Professional-Grade Construction: Each socket is forged from impact-resistant Chrome-Molybdenum (Cro-Mo) steel, ensuring long-lasting durability and strength for high-torque applications.
• Pinless Universal Design: The 100% pinless universal joint provides 360° of freedom, allowing for superior access and flexibility in tight or obstructed work areas.
• Enhanced Stability: An "anti-floppy" design ensures the extension maintains its intended angle and remains true to the fastener even after extensive use, enhancing precision and control.
• Complete Metric Coverage: Includes all common metric sizes from 10mm to 19mm, ensuring a no-skip set for a wide array of fastening needs.
• Secure Fastening: The 6-point configuration provides a secure grip on fasteners, reducing the risk of rounding and ensuring efficient power transfer.
