The Proto B942555 3/8-inch drive deep impact socket features the patented TorquePlus™ design, a high-performance drive configuration that engages fastener flats rather than corners. This radius-corner design shifts contact area and stress away from fastener corners, distributing load over a larger surface area to minimize slippage — making it ideal for stubborn, damaged, or soft-material fasteners.
At 2-3/4 inches in length, this 6mm deep socket provides the reach needed for recessed fasteners in automotive, industrial, and MRO applications. The 6-point configuration delivers maximum torque transfer and reduces the risk of rounding off fastener heads, even under heavy impact tool use.
