> 3 dayI needed 1/4-28 taps to refresh threads for stainless steel hardware on my boat. The hardware used 1/4-28 set screws to hold pieces of railing together. The box I received indicated 1/4-28 taps. After re-tapping the holes, I found that the set screws would no longer go in all the way. Then I checked the taps themselves. All 3 were 1/4-20 taps, not 1/4-28. Horrors, after I had already used them.

> 3 dayThese taps were much easier to use than I had expected, not having tapped anything before. Although its not likely Ill use them often, if ever again, Im completely satisfied.

> 3 dayOne of the taps (the bottoming tap) fell out of the box some time before it got put into the bubble-bag for shipping. If I had _really_ needed the bottom tap I would have raised an issue with the seller but the other two taps did the job for me (it was a through-hole that I ended up using in both cases). Perhaps they could make sure that all of the tap boxes are taped before shipping.... NOTE: You do NOT have to send me a replacement tap!!! This is the first time in my life that Ive needed a 4-48 tap. (for storage spots for the little flat & ball-ended tips of a dial indicator and a little electronic height gauge)
