GSMotorrad,
Am I missing something? I understand the piece locks onto the socket, but what keeps said piece locked onto the extension? Wouldn't the socket stick to the fastener with said piece stuck to it? Or does it somehow lock onto the normal extension?
lilscorpion is correct in all regards. It's supposed to come with the allen key for its set screw, and that allen wrench is also supposed to be made in the USA as well.
The female end has the set-screw, so it's not permanently attached to whatever extension. With a little fiddling, it can be used on whatever length extension you need at the moment. For poorer people who aren't on flat-rate (like me), it's a small inconvenience to pay.
After reading about people breaking that part on the Blue-Point locking extensions, I'll be extra cautious, because these are my first S•K tools, and I've heard it's a difficult warranty process.
A set screw. I have some that came with a set screw and some that didn't. The ones that didn't, I tapped the hole and added one in a few minutes. When attaching one to my 36-inch extension, I can easily slam in the bell housing bolts quickly. Probably the only way it would be easier is if I could find a magnetic universal impact socket...that would be sweet!
That's an excellent idea, lilscorpioin. If you've modified these thing by tapping threads already, it seems like it wouldn't take much to JB-weld a magnet into a universal/swivel socket or something.
