Just a warning, please do NOT buy a Sealey 10-80Nm torque wrench, it's an absolute POS, the locking nut is super stiff and the clicking mechanism when getting to the desired torque is so subtle it's barely noticeable! Feel like a total fool taking a risk on this, was a good deal on amazon, but cost me a snapped a cylinder head bolt, so please learn from my mistake and buy quality. Ended up buying Halford Advanced and it's worlds better!
