HOSCO Open Jack Wrench securely aids nut-fixing.

H-OJW prevents the open jack from rotating when the nut gets tightened, reducing the risk of wire breakage.
As long as the dodecagonal concave on the wrench snugly fits to the hex nut, you can tighten it securely, instantly and easily.

Features

Easy to operate

There will no longer be any need to remove the coverings, like ST-type boat jack plates, pickguards or control plates : anybody can easily tighten the nut in a minute.

Connection secured

The distinctive shaft, focusing on immobilizing jack points, prevents the open jack from rotating and eases the nut to get safely tightened.

Caution

1. Please note that it is designed for use with 1/2” hex nuts.
It can also be used for metric nuts when tightened, depending on the tolerance.
Check how well your nut fits to the wrench before operation.

2. Over tightening may fail in holding the point still to end up with disconnection.
