The Proto B941577 is a 3/4" drive thin wall deep impact socket featuring the TorquePlus™ design — a high-performance drive configuration that engages fastener flats rather than corners, distributing contact stress over a larger area to minimize slippage and reduce fastener rounding. At 1-15/16" long, it is ideal for stubborn, damaged, or soft-material fasteners where standard sockets may fail.
The radius-corner TorquePlus™ internal geometry shifts stress away from fastener corners, delivering superior torque transfer and socket longevity under heavy impact use. This thin wall design allows access in tight clearance applications where standard deep impact sockets won't fit, making it a reliable choice for professional MRO, automotive, and industrial applications.
