123 Blocks are a common accessory found in nearly every machine shop machine shop and are useful for numerous work support, set up and inspection tasks. 123 Blocks are even becoming more coming on woodworking and DIY shops. What makes 123 block so useful is they’re made from hardened steel and precisely ground (withing 0.0002”) to 1” x 2” x 3” with all sides being square to each other.

Several problems arise when attempting to join several blocks together: 1) the holes in the sides and faces are not the same distance from the edge and when different faces are bolted together these are steps or offsets, and 2) using readily available bolts and nuts will leave hardware proud of the block’s surface interfering with the task at hand.   This 123 Block Attachment Hardware Kits addresses the above bolting limitations. This hardware allows joining blocks together with all hardware buried within the blocks. The hardware is also slightly smaller than the holes allowing edges and faces to be joined together with faces being flush with each other.

To use, insert a through hole dowel into a block hole and thread a screw through the hole. Next insert a threaded dowel into a hole in another block and screw and tighten the screw t into this nut to secure two blocks together. Each dowel has a straight screwdriver slot in line with the hole to assist in getting the dowels perfectly lined up to accept the bolts.
