Gee, I found some small 1/4 deep socket (sockets with an internal lip, some sockets do not have this lip, mine are Snap-On) that fit over them, added a 1/4" extension bar and gave 'em all one swift smack with a brass hammer...They all just popped through and yet looked rather re-usable. (maybe need the barbs straightend as John mentioned, I didn't look yet that closely)
