Greater than one weekI used grade 8 bolts into schedule 40 pipe after drilling and tapping. The tap started and cleaned easy.

> 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 dayI needed a bottom and plug tap for 8-32 metal/jewelry working and it took awhile to get all 3 types in one item and purchase price separately was not as good as this offering. They look perfectly all right, so it was felicitous.
