    • 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
