Rated 5 out of 5 by from Needed it, PepBoys had it My Audi Q7 was up on jack stands and I realized that I didn't have the correctly sized triple-square bit. I tried Autozone, O'Reilly's, Harbor Freight, Home Depot, and NAPA...only PepBoys had this triple-square bit in stock. While the price is a little high for a single bit, you can't beat actually having products on-hand!

Rated 5 out of 5 by from Just what I needed when I needed it!!! Pep Boys was the only place in a 25 mile radius that had this 16mm triple square bit in stock when I had my Porsche Cayenne GTS in the air changing my rear rotors. Hats off to them!!!
