#2 x 1 Tamper Resistant Phillips Insert Bit (1/4 Hex)
FMW shipped promptly without error. However USPS sent the package to Virginia instead of Oklahoma. It stayed there for a while until finally getting to Oklahoma. Then postman did not deliver because it was raining I guess, so had to drive to post office 10 miles one way to retrieve package.
I wish you made easily available corresponding panhead zinc #8 2-1/2" sheet metal security screws for the Phillips pin-head bits that I ordered and your shipping methods were less bulking and more economical.
