Features/Benefits

* Used to quickly and easily remove and install both 2H-3778 Spanner Nuts, the lock nuts for Extend-A-Mat® B Screed extender sloper pivot pins (assembly requires an inner spanner nut, star washer and outer spanner locknut)

* Used with 3/4inch Square Drive Torque Wrench (torque specification for two nuts is 545 ± 25 N·m [400 ± 20 lb ft])

* Due to its location, nut is extremely difficult to access using any other tooling

* Wrench uses an inner pilot to prevent it from slipping off during removal and installation of inner spanner nut (makes removal and installation much easier)

* Pilot also keeps wrench teeth engaged in spanner nut when removing and installing outer locknut (helps prevent slippage, resulting in damage to nut or injury to mechanic)

* Wrench is heat treated for improved durability
