HHIP 3402 0905 Coated Block - Enhanced for SEO Review

I bought these blocks on purpose based on reviews that said they bolt together and that the unthreaded holes are big enough to let bolts through (as the design of these blocks suggest leaves). ). Well I got them today and the unthreaded holes are NOT big enough for the screws to go through. This severely limits the adjustment options when they are bolted together. I'll be back. I gave them 2 stars because the case closes well and the blocks are not properly engineered but come oiled to prevent…

I recommend using a threader, not a faucet, through the threaded holes to clean the surface as some of them can get dirty. So to the guy who gave…
