Using your Klein Tools 68508 8 mm Metric Combination Wrench is a breeze. For tight spaces, use the open end with its 15 - degree angle to get a good grip on nuts or bolts. When there are obstacles around, the 15 - degree offset box end will come in handy. Just place the appropriate end of the wrench over the fastener and turn it to loosen or tighten. As for maintenance, keep it clean after each use. Wipe it down with a dry cloth to prevent dirt and debris from building up. Since it's corrosion - resistant and nickel chrome plated, it's quite durable, but try to avoid leaving it in wet or humid conditions for long periods. And always store it in a dry place to make sure it stays in good shape for a long time.
