The other day I was meandering my way through our ecommerce website  and found myself in our Hand Tools/Wrenches category which brought up four additional sub-categories, SAE, Metric, Crowfoot  and Special Use.

Special Use Wrenches?

I remember the days when a wrench was just a wrench and if you had an adjustable wrench you could just about fix anything!

Nowadays, your tool box isn’t complete unless you have a huge assortment of wrenches that do just about everything. Some wrenches don’t even resemble wrenches!!

Now I will go out on a limb here and assume that you already know what a combination wrench is as well as a ratchet wrench so I won’t bore you with those but there are a few wrenches that threw me for a loop.  I thought I would share some of the non- standard wrenches with you.

Flare Nut Wrench

A flare nut wrench, also known as a tube wrench, is used for loosening softer materials like brass because it allows for maximum contact with the fastener, which keeps it from rounding and being damaged. These are good when you have a rusty old brake line that needs to be removed. See all Flare Nut Wrench Sets

Spanner Wrench

A spanner Wrench has some kind of hook and a long handle. Some have pins that will engage, giving you more torque power.

The long, generally thin wrench works well with hard to reach places.

These are rather specialized wrenches for a particular job. For example we have spanner wrenches for removing:

  • slotted retaining rings  in hard to reach areas
  • Timing Belts for some 2004-2005 VW/Audi models
  • Fan Clutches  for GM, Jeep and Dodge trucks, vans and SUVs with pressed on water pump pulleys
  • Front Axles for the Two Wheel Drive Geo Tracker
  • Ball Joints  For the removal and Installation of the ball joint retaining sleeve on the 1/2, 3/4, and 1-ton Dana open yoke front axles found on GM, Chrysler, IHC, and Jeep 4WD vehicles

Crow Foot Wrench

There wrenches are not needed that often but when they can be quite handy to have in your box. Use with a ratchet handle or breaker bar allowing you access or strength to nuts that you may not have been able to tackle with a standard socket. They come in flare nut as pictured or in a straight side. Because they don’t have a handle they are perfect when space in your box is a premium.
