Proto 1/2" Drive 4 Piece Impact Extension SET J7515A-SBD

Proto's professional-grade 1-13/16 inch SAE tether-ready impact socket engineered for high-precision industrial maintenance and heavy-duty assembly. Featuring a 3/4 inch drive and a 6-point configuration, this tool is designed to provide maximum surface contact on large fasteners to withstand high-torque impact applications while ensuring a critical safety layer for elevated work. The integrated Positive Control System requires a separate tool for attachment or removal, ensuring the socket cannot be accidentally detached—a vital safety feature for preventing dropped objects in "at-height" environments. Built with a heat-treated alloy and a durable black oxide finish, this impact socket is designed to resist wear and corrosion throughout a demanding service life.
