The Combination Wrench
Standard wrenches or "flat wrenches" are typically one of three types.   They are either a box end, open end or combination wrench.  The most common is the "combination" wrench (pictured below) witch has both the box end and the open end.  This is the most versatile type wrench and sometimes needed when working on the NSX.  Use the box end as much as possible to prevent the rounding off of your fasteners and knuckles as it grips the head on all six sides.  Use the open end only when necessary.  In tight spots, where the wrench doesn't have much room to turn, the open end can be flipped over and over to  loosen the fastener, this is why the end is angled.

Sizes Needed: 10mm, 12mm, 14mm and 17mm.

Tip: Ace Hardware has a "gear wrench" which incorporates a ratchet into the box end which is a real time saver especially for removing caliper bolts 14mm, and caliper bracket bolts 17mm and sway bars 17mm.

Socket Wrenches
Socket wrenches are by far the most common tool used when working on the car.   Sockets are like the box end wrench, they grip all six sides of the hex-headed fastener.  Socket wrenches are comprised of a socket and a drive tool.  There are four common sizes for the socket-to-drive tool interface: 1/4", 3/8", 1/2" and 3/4" these sizes are referred to as the "drive size".  Since your torque wrench will probably be 1/2" drive, it makes sense to buy 1/2" drive sockets.

Sizes Needed: 10mm, 12mm, 14mm and 17mm.

Sockets also come in 6 point and 12 point styles.  This refers to how many "teeth" the socket has.  Generally it's better to go with the 6 point style as they fully grip the fastener on all six sides which will resist rounding the fasteners.  Sockets also come in a "deep well" style which are useful when working with long screws and places where the wrench needs a little more clearance to turn.  I have a 3/8" 10mm 6 point deep-well socket attached to a 3/8 ratchet which seems reach almost all the 10mm screws in the NSX.

The most common drive tool is the Ratchet.  I won't explain this tool any further because you already know what it is.  In fact, this tool is used so much, it's worth having at least one good one in your garage.  FACOM makes a real nice ratchet with 72 teeth (48 standard) which makes working in those tight spots easier.  This has been one of my favorite additions to my tool collection.  TIP: to put a ratchet in tightening mode, turn the control counter-clockwise, clockwise to loosen-- this is counter-intuitive, but remembering this tip will keep you from testing the direction of the wrench every time you use it.

Adapters are available to convert your drive sizes, for example I have a micro-torque wrench and an air ratchet which are 3/8" drive, to use my 1/2" sockets with these tools I use a 3/8" to 1/2" adapter.  Extensions make getting at those hard-to-reach fasteners possible.  Having several different lengths is a good idea like: 3", 5" and 10" for starters.  Universal joints and wobble extensions are not used often, but come in handy--especially working with the exhaust system.

Crush Washers
Crush washers are used in various places on NSX, like the oil drain plug, transmission drain and fill plug, on either side of the fuel filter banjo bolts and on either side of the brake line banjo bolts.  These washers are made of soft aluminum and when you torque a bolt down on them, they "crush" a little bit and make a perfect seal between fasteners.  These washers need to be replaced for three reasons: 1) they only crush once, so after that they won't have as good of a seal compared to new ones. 2) The suggested torque recommendations assume that new washers will be used so the torque specification allows and assumes this crushing will take place.  And 3) the service manual says so.
