Bolts used to combine two blocks keep the 1/4"-20 SHCP while the Stud Pins start with a 5/8"-11 thread and flare out to fit snugly into a 16mm hole.
These blocks have several useful configurations:
Use with Tooth Block to create right angle bracket.
Use with Tooth Block or other extension blocks to create a 4 sided frame square.
When joined into a right angle bracket or a 4 sided frame, the height becomes 14” which is the same height as our 14x5x5 Cast Tower Block.
