We found this press release under the desk here in the office, which explains why we didn’t pass this on back on October when it hit the street: SK’s expanding their “universal spline” line from wrenches to sockets with a number of different kits now on the market.

For those not familiar, their “universal spline” sets use a uniquely-shaped tool end to grip six-point, twelve-point, female Torx, square, and even 50% rounded fasteners.  A pic past the jump illustrates how the shapes fit together.


The new (ok, relatively new) sockets are available in 3/8″ drive standard and deep as well as metric sizings.

We’d provide a direct link, but the SK site is infuriatingly difficult to direct-link.  You’ll have to click on the link below, then select “Product Catalog” then “Chrome Sockets and Drive Tools” from the 3/8″ drop-down, then “Spline” from that.  Or just forget it and go look at one in the store.

Street pricing starts around $120 for the 45-piece fractional/metric set.

    “50% rounded” looks like the socket to use after using the wrong socket.

    Hope they work better than the SK flare nut wrenches I bought a few years back, that had more stretch and rounded more fasteners than the cheapo Chinese set they were replacing. SK’s not getting any more of my money.

    I’m curious as to what kind of metal the set’s made from. I tried your link and unfortunately got a “Not Found The requested URL /index.cfm was not found on this server.” I was hoping to check the specifications. I see it was listed under Chrome Sockets, so it’s probably steel with plated chrome. If you don’t use it much it would probably be good enough for use around the house, and can deal with many different nuts. But if you use it a lot , it probably will get stripped and you’ll end up buying a new socket.
