Worked great as expected
They worked great. Rockler and Kreg are both quality and dependable so I wouldn't expect anything less.

Not like other T-bolts - better!
I've ordered these same type T-bolts from other suppliers in the past. I could get them in the slot, but I had to finesse them. Rockler's T-bolts fit perfectly the first time! Don't bother with anyone else. These are the real deal!

high quality t-bolt
These are perfectly made. It would help if the head was 1/2" to fit in a 1/2" router groove. Has small tabs on side so it doesn't quite fit.
