5/16-24 tap, please help
 

I am working on the door pins, and the directions call for tapping two inches inside the locking pins with a 5/16-24 tap. My taps will not work, as they have about 7/8" threads then have a larger shank. I ordered Irwin taps on Amazon that showed a smaller shank, but the photo was of something else and when received they also have a large shank. I am still looking for a reasonably priced tap to do this with, I found one online for ~$70 but that seems excessive. Any advice? I called Cleveland and Avery but they do not have anything.

these guys have a lot of taps to choose from, here's an example with 1 1/2 " of thread:

The 60 piece tap and die set from Harbor Freight has the smaller shank you are looking for:

Perfect, thanks. I had not thought about a cheap set would have less steel thus the small shank I need. Going by HF tonight.

Try mscdirect.com, they should have it

VC62491097 , $22.99 could work. I would call them and ask.

ENCO has 6 inch long 5/16-24 tap with undercut shank for $25-28. Catalog # 326-1526 or 337-4612. Those will be the best option for you. ENCO on line address is use-enco.com

Thanks for the info, that long tap looks perfect.

This is what I used.
