These Irwin Hanson taps are ideal for general-purpose threading, producing a class 2B thread. We offer them in two sizes corresponding to the most common grease fittings found in North America. Great for replacing press-fit Zerks that keep popping out, or retapping old threads in the field.
Note that the thread descriptions can be counter-intuitive. The 1/4"-28 tap is smaller than the 1/8" NPT tap. 

We also offer T-handle tap wrenches for both sizes here.
