1/2 in Drive, 9/16" Triple Square SAE, Socket, 12 Points, Steel, Chrome, 9/16 in

Ideal for use on stubborn or damaged fasteners, as well as those made from soft materials, this 9/16 in triple square socket features a TorquePlus design for quick and easy engagement. The radius-corner design minimizes slippage and reduces fastener rounding, extending its life. This makes it perfect for use on worn, rounded, or rusted fasteners. Suitable for a wide range of applications, including construction, automotive repair, and heavy industry, this socket is a reliable choice for professionals and DIYers alike. Its durable steel construction and chrome finish ensure long-lasting performance and easy cleaning.

Top product features:
