Very good to keep around your workbench. Easy access to frequently used lengths. Good weight to them, too.

    • Dimensionally correct
Size: 2" x 4" x 6" Style: 23 Holes
Both 2-4-6 blocks dimensionally within the advertised tolerance on all sides as checked with a recently calibrated Mitutoyo caliper. Have an old set I normally use, but needed to make a jig exactly that size for some work and realized that buying these was cheaper than driving over and buying (or getting one shipped) a block of A36 steel and machining it to a 2x4x6" block. Looks to be decent quality and exactly as advertised. Came packaged in oiled paper that would have kept them rust-free for several decades in a warehouse. For this price, would buy it again if I needed another. ... show more

    • Like them
Size: 1" x 2" x 3" Style: 23 Holes
Dimensions are accurate and they are well made. Little pricy for what they are. The come well packaged with a lot of oil to prevent rust so be prepared to use some brake cleaner to clean them up before use.

    • Great Value
Size: 1" x 2"x 3" Style: No Holes
The package these arrived in had five layers of packing tape wrapped around it and the blocks appeared to be a rusty mess, HOWEVER, what looked like rust was just a red paper and grease wrapping that easily washed off. The blocks were in perfect condition. Both blocks measured 1"x2"x3" within a couple thousandths of an inch. Both weighed exactly 27.1oz (768g) each. I'm very pleased with these. ... show more

    • Great weights!
Size: 1" x 2"x 3" Style: No Holes
My use case is maybe unconventional, but I got these to use as weights for fabric and patterns when sewing. For what its worth, they seem to be true to size, but also work great for my purposes. The edges are slightly beveled to avoid sharp edges and corners, which is nice. They come packed in wax paper and grease to prevent rust in shipping, and it all comes off pretty easy with a bit of soapy water. Have 6 of them so far and am happy with the product. ... show more
