I can never remember the actual torque figure but they are supposed to be pretty tight. (a fact that I overlooked for quite a while but got away with it)Yes normal socket, it shouldnt even be too tight
My socket set is only a 12 pointer but always managed to get them off. Occasionally i've needed to resort to the torque wrench as it's twice as long as my socket wrench, and sometimes had to stand on the end... but normally not.
