Trying to get a stubborn crankshaft bolt off? This Powerbuilt socket set makes it way easier. It includes three of the most common sizes—17mm, 19mm, and 21mm—and they're specifically designed to be counter-weighted. That means when you use them with a 1/2-inch impact gun, the weight helps break loose even the most seized-up bolts. The sockets are impact-rated and built to exceed ANSI standards, so they can handle professional use. They come in a tough, heavy-duty case to keep everything organized in your toolbox. No more struggling with regular sockets or risking damage. If you're doing timing belt jobs, harmonic balancer replacements, or any engine work where the crank bolt is stuck, this set is a total time-saver. Just grab the right size, hook up your impact wrench, and let the weight do the work.
