Description

The Hosco open jack wrench is designed to prevent open jack sockets from rotating while tightening the nut, helping to reduce the risk of wire breakage.

With a precise dodecagonal (12-sided) shape, the wrench fits securely onto 1/2″ hex nuts, allowing you to tighten them quickly and easily.

This tool is ideal for stabilising loose open jack terminals, ensuring a firm and reliable connection. Note: This wrench is designed for 1/2″ nuts – using it on metric nuts may cause damage if forced.

With the Hosco open jack wrench, you no longer need to remove jack plates (such as ST-type boat jack plates), pickguards, or control plates. This tool allows anyone to tighten the jack nut quickly and easily.

The Hosco open jack wrench features a distinctive shaft that securely holds the jack point in place, preventing the open jack from rotating. This design makes it easier to tighten the nut safely and securely.

The Hosco open jack wrench is designed for use with 1/2″ hex nuts. While some metric nuts may fit depending on their tolerance, always check the fit before use. Avoid over-tightening, as this may cause the jack point to slip, potentially leading to disconnection.
