You should select a tool appropriate and convenient for the job. Most problems encountered are due to seized, rusty bolts or screws. In serious cases the bolt or nut must be drilled out or cut open to permit removal. It is therefore important to select tools carefully to minimise the chance of rounding (damaging) a nut/bolt. Where possible a ring spanner or socket is the best choice.

When tightening bolts be careful not to overtighten - it's surprisinly easy, especially with aluminium bolts. Take especial care to avoid "cross-threading" where a bolt is tightened when not sitting straight. This can often be detected by the bolt becoming tight before the surfaces have mated (touched).

Remember: Anti-clockwise to undo, clockwise to tighten when looking down on a nut or bolt-head.

Tips for dealing with stuck nuts, bolts and screws:

  • Apply heavy downward force to ensure tool does not slip off/out, failure to do this is the most common cause of damage
  • Tap stuck threads (bolts) from one end with a hammer - sharp taps - to unstick
  • Heating (eg. with oxy torch) often loosens bolts on exhaust systems
  • Apply spray lubricant 12+ hrs. in advance e.g. WD40
  • Tap spanner/wrench with a hammer if you can't move it
  • Replace any damaged nuts/bolts/screws

Hey just trying to learn basics on car maintainence

Video quality is excellent, but audio is faint- bad pickup, lot of ambient noise. Of course your conditions are more challenging than the rest of us in front of computers doing recordings!

Showmedo is a peer-produced video-tutorials and screencasts site for free and open-source software (FOSS)- with the exception of some club videos, the large majority are free to watch and download.

Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can emailus for advice or just use some of the how-to screencasts on the site. This screencasting learning-pathis a good place to start.
