Alexander O. ★★★★★

Finally got this to connect my old impact driver to a newer chuck that uses the 3/8" shank, and it fits perfectly with zero play. The threading is clean and started easily without any cross-threading. Saved me from buying a whole new tool set.

John T. ★★★★★

I was worried about wobble, but this adapter threads on smoothly and holds the 3/8" shank securely. It solved my problem of using a specific drill bit with my impact driver.

James Z. ★★★★★

Finally found this adapter that actually fits — the 5/16-24 female thread mates perfectly with my 3/8" shank extension, zero wobble when I run it. Solid little piece, does exactly what it's supposed to do.
