PERFORMANCE TOOL 4-PIECE METRIC TRIPLE SQUARE SERRATED BIT SET

This Performance Tool W1395 set gives you four essential metric triple square (also known as XZN) bits: 5mm, 6mm, 8mm, and 10mm. These specialized bits are crucial for many automotive fasteners, especially those found on German vehicles, which often use triple square head bolts for components like cylinder heads, brake calipers, and suspension parts. Having the right bit ensures you can properly engage the fastener without stripping it, which is a common problem with standard hex or Torx bits.

The bits are made from durable steel, built to withstand the torque required for stubborn bolts. Their triple square design offers more contact points than a traditional hex, distributing force more evenly and reducing the risk of cam-out. This set is a practical addition to any mechanic's or DIYer's toolbox, providing the specific sizes needed for many common automotive jobs where standard tools just won't cut it.
