If you can't get a secure connection on a nut then you run the risk of rounding it or taking more time than necessary to find a way to undo it. Having a range of tools to give you the flexibility to get to any fastener, in any location will prevent unnecessary damage and save a great deal of time.
Flexible Head Ratcheting Combination Wrenches give you another option when you need to address a fastener in a challenging location.
These Jonnesway Flexible Head Ratcheting Combination Wrenches have a 72 tooth mechanism that produces a very small 5deg of arch between each tooth. This means that you can undo nuts that have only a minimal degree of clearance.
They are made from Chrome Vanadium, have a mirror finish for easy cleaning and a Patented high torque design that exceeds ANSI and DIN standards.
