Adequate for small projects however two bolts would not advance directly from top block over bottom block. This meansmis-alignment off holes by fractions of an inch. Certainly not a10,000th shop and not even a 5,000th shop. Helps keeping small parts on angle for model making. Prototype etc.

Can't join them together. Included bolts don't match the threads in the blocks. Wish I had tried to join them together when I first purchased them so I could have returned them.

People don't understand about threadedHoles and precision surfaces.No one makes marching theaded holes when assembling to 123 blocks together.Take a Dremel and grind away the threads so they don't engage the top block. Can be machined off of ground in a T&C grinder. Or a punchmate on a surface grinder. 45 years Tool and Dis Shop Owner.
