Designed in the UK, the Hall 3-Way Banjo Wrench / t-wrench / banjo Key is the best there is.
It is a daily essential tool used at our own busy workbench. The large size and shape of this wrench has a better “feel” which results in a better sense of how evenly you can tighten down the nuts when tensioning a new head compared to the typical small T-wrenches. It eliminates any need for a torque wrench.
High quality machining of the Hall 3-Way Banjo Wrench ensures a much cleaner fit to new tension-hook nuts and prevents marks or rounding off the edges of the nuts.
All three of the commonly used sizes; 1/4″ – 9/32″ – 5/16″ – fits virtually all modern banjos.
