Taytools Pair Hardened Steel 123 Blocks and Attachment Hardware Kit

Excellent quality blocks, including fasteners so you can use these for longer right angles as well as straight measures.

ok, have not actually used this other than unwrapping and cleaning it but does measure square. It came well wrapped and covered in oil so that had to be cleaned. Machining looks good, no case but good deal for the price. Will be used for making model structures where I need square walls. I think it will be fine for that, good tool to have in your kit.

These are very nicely made and are even handier with the joining hardware. I highly recommend this product.

These 1-2-3-4 blocks seem to be well made and help make tool setups, squaring, and 90 degree glue ups a breeze. It came with bolts to group them together but they are a little challenging to use (the bolts are small and the inserts tend to spin). The blocks came wrapped in an oil soaked paper which I assume was to prevent rust from forming during shipping but it was an oily mess and required clean up before I could use them. It’s still embedded in all the little holes so I will working on that for a while. You don’t want get that stuff on your wood projects. Alcohol seems to cut through the oil and I sprayed it with an anti rust spray that is made for sharpening chisels and that’s working well so far. It also would have been nice to have a little box to store them in but that will make a nice weekend project down the road.

These are must have for model railroad and other similar craft tasks. Heavy for bracing and holding and precise for squaring the work.
