Unlike other nut keys where your hands get raw from clenching so hard - dislodge jammed nuts with the help of the DMM Nutbuster and do so with happy hands as the wide rubber handle makes it easy to hold.
Under the rubber handle, a 17mm spanner can be used to tighten loose bolts and we're pretty sure there's the possibility to crack open a beer with the key too.
DMM's top tip: Tie a small loop of 3 or 4mm accessory cord through the hole in the handle and use this to attach the Nutbuster to your racking biner. This reduces the danger of stabbing yourself with the nut key in a fall situation.
DMM is an awesome recreational climbing and mountaineering equipment company from Llanberis North Wales. Founded in 1981 they still make and test all their gear from home.
