When working on your engine or taking apart another system, always use the right tool for the right job. Taking proper care of your hardware will allow reuse, will ensure proper torque, and won't round off the heads or tool attachment points.
Here are some examples:
It is always better to use a an open end or line wrench on a line,
and a box wrench on a bolt.
Using an adjustable wrench can round off the corners of the bolt or hex making your next repair more difficult.
It you find someone has already rounded off the corners, using a vice grip or small pipe wrench are your best options.
There are so many hose clamps on a boat and, they are generally found in hard to reach places.
Checking for tightness of clamps should be part of routine maintenance.
Rust on a clamp is usually a sign that it is deteriorating and needs to be replaced.
Using a flexible nut driver on hose clamps allows the tool to set squarely on the fastener head no matter how challenging its location.
Always take time to reach for the right tool and avoid making more work. At times, finding the right tool for the right job might take a little longer, but it is well worth it.
