First thing I did with one of these unwrapping it, is drop it, corner hit the metal table then bounced off onto the concrete. I figured being a cheap Amazon purchase it would be damaged, but no burs on the corners and no dings I could see or feel. I pulled out the caliper and the 1" side was .0005 under, the 3" side was .0005 over, and the 2" side was spot on. Tight enough tolerance for the work I do but to let others know if they need tighter tolerances. Should be handy for me.

Decent quality blocks. Took the calipers to them just for giggles and they seem to be pretty much dead on in all dimensions. Used them to help set my good table saw fence and some other tools, plus as a nice heavy stop block. For the woodworking I do, they're a great multipurpose gauge/tool. The tin coat is nice as well. I only gave them 4 stars for the rough threading in the tapped holes, but not a deal breaker.

I'm using these mainly for setup in my shop. I got two sets, and the price is right.

These blocks are made in China BUT for Chinese junk these are very good. Why? Well they are accurate on all measurements coming in at exactly 1.000000 x 2.000000 x 3.000000 verified on via my probing machine. They are perfectly square as well. The bolts are properly threaded for 3/8 x 16 bolts and there is enough meat on the untapped holes to tap them on a mill if needed. I do recommend running a thread chaser not a tap through the tapped holes to clean out the coating as some of them may be dirty. So to the guy who gave them one star you know the creep in the street guy well he either a didn’t clean the threads or b used the wrong thread pitch bolts. Either way he is a whiner as he is crying about very cheap Chinese blocks. If he wanted perfection he shouldn’t have gone out and bought an expensive precision set but he didn’t cause he’s cheap and just wants to complain because he’s a troll.

I received the same blocks as AnFCUser.The same blocks that sell for $10-12.The untapped holed are too small for 3/8 bolts.End holes are untapped and too small for bolts.Returned.

These blocks are quite good considering what they cost. I have measured them and they are typically within 5 tenths of a thousandth from the nominal dimensions. Even though the absolute dimensions are a little off from spec. They are parallel and square. For setups, they are accurate enough for the typical machine ops. The finish and workmanship is also very good.
