Reddit mentions of Draper 19776 107 Piece Mechanics Tool Set

A good socket set is a must but I wouldn't go for the one you linked to. People debate about how important it is to have a high quality set and I think the only answer is to work out what you've got to spend. I spend a lot on tools but my Dad has had a cheap socket set that's worked fine for the past 30 years and it's still going strong. So my advice:

1. Socket set.
   
   a) Quality:
   Work out how much you can afford to spend. You don't have to have the top brands but I'd avoid the very cheapest stuff. But something by Stanley or Draper should be fine.
   
   b) Range of sockets:
   I would go for the largest one you can afford. You'll be surprised how many different sized sockets you use and how useful the extensions, universal joints, etc. are.
   
   c) Sockets:
   I would go for sets that only have metric sockets. Most modern cars have metric nuts and bolts, so unless you're working on a classic the imperial (AF) sockets won't be much use. This will also mean you get a set with a wider range of sockets that will be useful to you.
   
   d) Drive size:
   Ideally I would get a socket set with 1/2", 3/8" and 1/4" sockets and ratchet drivers. However, if you don't want to spend that go with one with 1/2" and 3/8". You can probably get away without the 1/4" for a while.
   
   Some socket sets are put together with auto mechanic work in mind. Look out for these.
   
   
2. Torque wrench:
   You'll need a torque wrench to make sure things are tightened up correctly. I'd go with a 1/2" one that have a good middle range to start with: say 20Nm to 120Nm or thereabouts.
   
   
3. Set of screwdrivers: Flat head (slotted) and Phillips (but I'd avoid Pozidrive)
   
   
4. Combination spanners/wrenches
   You'll need a good set of combination spanners. 8mm to 21mm should do to start with.
   
   
5. Hex keys
   You'll also need a set of these.
   
   
6. Other stuff:
   Various pliers, a wire brush, a rubber mallet, would also be useful.
   
   This might be a good start if you're on a tight budget. You can pick up the other stuff as and when you find you need them. I've probably left some stuff out but I'm sure other posters will point this out.
   
   Edit: I ballsed up the formatting of the lists. Please bear with me.
