This spline wrench has been my go-to tool for all my industrial works. As a result of using this product, I found that it delivers efficient performance and the pass-thru design makes it easy to use with any fastener shape. The adjustable jaw can be set to different sizes which save time and efforts. However, the handle is not rubberized which can cause slips if hands are sweaty. Overall, the Crescent Pass-Thru Adjustable Wrench is a must-have tool for any professional worker.
