The Large Ergo Wrench fits all standard imperial 3/8" Socket Head Bolts and size is 5/16".

I had one of these when they were made of fibreglass, but it broke. Glad they are now made of urethane. Fits perfect in the hand and large enough to get enough torque on it.

Super handy and super ergo

I love this little tool. It is super helpful when setting routes and really sits nice and comfortably in the hand. Not as clumsy as an impact driver. The rounded tip is great because sometimes the hold is just out of reach to get square to it, so when your reaching out you can still tighten and loosen bolts. Really happy I added this to my order

Great value

Has a ball joint type end, so easy to angle and use, the handle helps with the grip and looks cool! :-) Great value, too. Excellent service and delivery.
