The Proto B942957 is a tether-ready 12-point socket designed for 1/2-inch drive applications, offering a 1-1/4-inch opening for reliable fastener engagement in industrial and professional environments. The tether-ready (-TT) design allows the socket to be secured to a lanyard or tether system, making it ideal for use in elevated workspaces where dropped tools pose a safety hazard.
Built to Proto's professional-grade standards, the 12-point configuration provides more contact points for turning fasteners with reduced ratchet swing requirements, improving access in tight spaces. A dependable choice for MRO, construction, and manufacturing applications.
