The TORKEY-L is a long 5mm torque indicating security Allen key designed to help you achieve a specified tightness of 4-5 Nm. It does this with the help of its curved blue plastic handle. As you tighten the fastener the handle will slowly straighten - and once it is perfectly straight you have reached 4-5 Nm.
A handy and affordable tool to have for situations where accidental over-tightening could lead to valuable gear getting damaged.
