Made of top quality tool steel. 12 Point with 1/2" square drive, 13" long.
Excellent product. I like the thicker walls because you can sand them down exactly the way you want. Its nice having a set of four ranches and my only critique would be that they could be 1 inch longer to accommodate the Ted Smith AEROSTAR. However these wrenches are more than adequate if you are on an engine stand and not trying to work around cowling.
Used them for the first time to remove a cylinder from an O-360 Lycoming, they worked great, thought I may have to grind them down some for clearance, but actually they had enough bite that I didnât have to grind them at all and they worked perfectly. Itâs judt one cylinder so far but worked great.
Your basic wrench! Did the job just fine. Not a craftsman or snap-on but it works. May need to grind the side to thin the wall a little for some cylinders depending on the casting - but not in my case.
The wrenches dont fit the cylinder base hold down nuts on small Continentals! I am going to have to grind them as other customers did. However, I was out in the field, no grinder nearby, they were worthless, plus, I hate grinding a brand new wrench!
Fit perfect on A65 and did what was needed
Worked well on an O-470-R but needed a little grinding to clear two of the cylinder base nuts near the engine mounts. Good value.
These wrenches are solid and work great, but only after youâve ground down around the edge of where the nut sits. Most of the engine base nuts I remove with these are a closer fit than the wrenches allow. Iâve never came accros a base but wrench that works right out of the box, theyâve all needed to be ground down no matter the manufacture
These are essential to have and a great product. Aircraft Spruce has been my go to for Aviation Supplies for over thirty years. Thanks for your continued improvement and dedication to customer service.
Installed two cylinders on an O-200 yesterday. We had to grind the wrench down in a few places to get it to fit, but I dont know how I would have been able to torque the nuts down without these wrenches.
Purchased the 1/2 and 9/16 for use during the recent overhaul of my Continental O-200A. They worked perfectly and are a absolute necessity when removing and installing cylinders.
