The Proto B943816 3/8-inch drive impact socket features an 8-point configuration with the innovative TorquePlus design, making it ideal for use on stubborn, damaged, or soft-material fasteners. The radius-corner drive geometry engages fastener flats rather than corners, shifting contact stress away from vulnerable edges for a more secure grip.
By distributing contact stresses over a larger surface area, the TorquePlus internal design minimizes slippage and reduces the risk of rounding off fasteners, delivering high performance and reliability in demanding impact applications.
