The Proto B942942 is a tether-ready deep socket featuring a 12-point design for maximum contact with fastener heads, reducing the risk of rounding. Built for professional and industrial use, the 1/2-inch drive connection and 1-3/8-inch size make it suitable for a wide range of heavy-duty applications.
The tether-ready design includes a dedicated attachment point, allowing the socket to be secured with a tether or lanyard for safe use at heights or in environments where dropped tools are a hazard — ideal for MRO, construction, and industrial maintenance work.
