This hex wrench is a 1″ (25 mm) box wrench with a short handle and, therefore, requires less leverage so as not to over-tighten your part. We designed it for our ER-16 headstock as a collet nut wrench, but you can use it on any hex nut with a 1″ OD.
The tool is cut from a 1/4″ steel plate and has a tough, black oxide coating to keep it from rusting.
