طقم براغي نقل، 1/4 بوصة - 7/16 بوصة

The blind-hole trick finally works for me—these screws seated cleanly and transferred the thread location dead-on with zero wobble. Way more reliable than my old punch set for tight spots.

I was a little skeptical about using these for blind holes, but they grabbed the threads perfectly and transferred the location dead on. Saved me from re-drilling a misaligned bracket.

The threads seated perfectly in the blind holes, and the transfer marks landed dead-on every time—way better than my old punch set for this job. Even the 7/16" size felt solid and precise when I tapped it into place.
