Life sometimes gives you damaged or rounded nuts and bolts. Powerbuilt in turn specially designed the patented Zeon socket. The 28 Piece Zeon socket set combines the most commonly used SAE and metric socket sizes into one convenient package. The secret is the patented Zeon socket design - the more you turn them the harder they grab and hold damaged hex heads. The patented design will grip and turn hex heads up to 85% rounded. And they work just as well on new nuts and bolts. Zeon sockets are heat-treated to hardness HRC 38-56 for maximum strength and durability. And you'll drive the sockets with strength and precision using the included 90 tooth Powerbuilt XT90 ratchet. This sealed head professional-grade ratchet is the most durable ratchet in the Powerbuilt line. It requires just a 4-degree swing to engage the ratchet, making it ideal for the tightest spaces in the engine bay.
