The precision-fit teeth engage narrow slots in the ratchet mechanism for a positive click when fully seated on a fastener, ensuring reliable torque application every time.
Designed as part of the Proto System Pro TorquePlus™ line, this deep socket delivers exceptional performance and durability for heavy-duty industrial, MRO, and professional mechanical applications where standard-depth sockets cannot reach.
