Made of top quality tool steel. 12 Point with 1/2" square drive, 13" long.
So far very good
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.
Fit perfect on A65 and did what was needed
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.
Wrenches were ok. Had to grind down thick walls just to fit into the nuts.
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.
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
