Overview

This custom built Anti-Splat-Aero constant speed propeller wrench was created especially for you and your airplane. This tool is available in 3/4" and 5/8" sizes, its small, lightweight and easy to use making your propeller servicing and installations fast and easy. With just a few flicks of your wrist, the bolts are started and easily run in and torqued. The one end ratchets without removal from the bolts, and the other end is an extremely strong fully reversible Crows Foot for torquing the propeller.

This super wrench is constructed with materials that are very strong, (4130 heat treated steel) then electroplated to meet high standards and will provide you with years of service. Utilizes both 1/2 & 3/8 ratchets, torque wrenches, and extension tools. Crows foot end is offset 15 for double the versatility for difficult bolts behind prop blades.

Reviews

OUSTANDING! I highly recommend this wrench to anyone who needs to remove or install a Hartzell constant speed prop. I struggled with standard wrenches and crow foot wrenches only to have them flex and slip off of the lug nut. I tried using the Hartzell wrench and it didnt perform nearly as well as this wrench. I bought this tool with high hopes. It did not disappoint me. It makes removing and tourqing prop bolts very easy. I was absolutely amazed at how easy it is to use. The material is super hard very strong steel. It does not flex at all. I would not want to change out a Hartzell prop without it.

Wrench provides the exact angle and leverage to torque the Hartzel R hub 3/4” pinned nuts /studs. The tool could have been improved by tighter machining tolerances as I felt the free play of the tool on the nut could cause a slip under pressure.. I felt slightly uncomfortable pulling 80 foot pounds of torque pressure but It did not strip or slip off the nuts.

Really Nice tool! The ratcheting feature saves time and sore fingers. The open end offset is a must in tight areas. Keep it at 90 degrees to the torque wrench for accurate results.

As advertised, an excellent tool. The ratcheting end adds speed to the process and makes a one-person installation feasible. The only thing I like to see is a slightly rounded edge for comfort.

When I pulled this wrench out of the box I thought, hmm, a bit pricey for what it is. But, wow, after using it I highly recommend it!!! This tool is high quality and very nicely machined. It made installation of my Hartzell constant speed propeller an absolute breeze. I wont be loaning this tool out to friends without a deposit.
