Using your GearWrench 9412 wrench set is easy. First, identify the right size wrench for your fastener. The size is clearly stamped on both ends of the beam, so you can quickly pick the one you need. Place the wrench on the fastener and start turning. Thanks to the 72 - tooth ratcheting box end, you only need to turn it 5° to move the fastener, which is much more efficient than using standard wrenches. When working in tight spaces, the thin head and stubby length of the wrenches will come in handy. Just make sure to align the wrench properly on the fastener to get a good grip. As for maintenance, the bright, polished chrome finish is easy to clean. You can simply wipe it with a cloth after use. Also, keep the wrenches dry to prevent rust. The set comes with a tray for storage, so keep the wrenches organized in it when not in use. Remember, this set has a limited lifetime warranty, but to make the most of it, handle the wrenches with care and don't use them for jobs they're not designed for.
