The Proto 3/8-inch drive universal socket features a 6-point design with the patented SureGrip® finish for better grip and longer life on fasteners. The universal joint design enables accurate fitting at greater depths, making it ideal for hard-to-reach fasteners in industrial, MRO, and professional applications.
Proto's TorquePlus™ system combines a drive configuration that reduces the force required to turn the tool, a reinforced socket design that increases overall strength, and lead-in chamfers that guide fasteners smoothly into position for faster, more efficient work.
