Machine taps for metric thread in tolerance classes 6G, 7G, +0.1 and 4H
The tolerance class decides how much clearance the finished thread has. 6G and 7G deliberately leave room, for coatings among other things; 4H is tighter than the standard class and is called for where the fit has to hold. Machine taps cut the thread in a single pass and run in a drilling machine, a machining centre or a tapping attachment.
