Anyone know where these can be had, USA made and some sort of sizing chart available?

Seems all of Europe has this style fastener drive but scant few choices here in the USA. While a Torx will fit and most times allow removing its immediately noticeable those aren't the right tools for that job. A T55 is too small with way too much slop, T60 is too big. I need one to suitably remove/replace seat base bolts on E-Series vans but certainly these are used in many other vehicles as well?

Been to Google, looked at Snap On, Cornwell etc etc but so far nothing like I want which is hardened male ends, short in the 50-55mm overall length.

Anyone with any knowledge of this would be very much appreciated!

TIA

 

Something like this?
Amazon.com: OTC 5904 12 Piece Ribe Bit Socket Set: Automotive
OTC tools are usually pretty good.

 

Those are them exactly---of all the places I do look Amazon was not on that list! Thank you Sir!

OTC used to be 100% Made In America but much of it is Chiwanese these days---maybe done to be more affordable. I've used some of their suspension tools, made in the 80's and early 90's---right up there with Moog and the other greats.

Thanks again!
