• 12-point opening fits double hex (12-sided), hex, and square-shaped fasteners

• Extra-large die-stamped size markings are easy to read and can’t wear off
• Polished, chrome-plated finish easily wipes clean and is highly resistant to corrosion
• Four detent grooves provide a secure connection with the drive tool
• Beveled inner rim of the socket opening helps guide it smoothly onto fasteners

Tekton 1/2 inch drive 12-point sockets are an exact fit for double hex fasteners and also work with hex and square shapes. They're designed to grip the sides and not the corners of the fastener heads, which prevents round-off. Their extended length allows the deep socket to fit over long fasteners and reach into recessed areas. The large, die-stamped markings are permanently impressed into the material and optimized for readability.
