123 Blocks Attachment Hardware Kit

Simple, easy and cheap. It allows the 123 blocks to be configured flush so they can be used to check the square on many other devices. Works for me.

Kit arrived with all parts as specified. Nothing missing.I also bought the Bessey c-clamps, which work very well at fixing the blocks in place to act as a stop or mini-fence.I use this 1-2-3 block combination mostly for drill press alignment and fixturing.The 8-32 bolts allow a considerable amount of play which allows for flexible alignment. Because of this play, plan on using a flat surface AND straightedge to get adjacent edges perfectly flush. The fine thread pitch (32 tpi) makes it easy to clamp the blocks tightly, using moderate hand torque. Once snug, the blocks stay securely in place.Having all fasteners completely inside the blocks is the best part.Easy to use without interfering with your setup.

These work great

Same problem as another reviewer. Threaded inserts were missing. Only non-threaded inserts provided. Poor quality control for kitting (pick and ship). I can use some parts in the kit and make it work. The parts supplied saved me about 15 minutes of work. I had hoped that I would not have to make my own. I should have known better. 🙁

Good purchase, I want to make these,when i have time.

Neat concept, however the two threaded inserts were missing from the kit. Great idea, however they are worthless when the kit is incomplete. Very unhappy with the purchase. Will return them today.

These are need when using 123 blocks. work great.
