I not only read what reviewers say, but look to see what their pictures reveal about a products true quality and description. I aim to not only feature the products I review in many different aspects, analyzing many qualities, I also provide my own opinions on ALL the good AND bad experiences I have with the product I review. I take time to learn and use a product as it was intended before I review it, and I have used this specific product thoroughly. My rating system: 5 - Met all my expectations. Was described and pictured perfectly. Exactly what I wanted and needed. Extremely useful product and a great value. Would recommend to family and friends. 4 - Very good product. Exactly as described. May have a minor flaw, mentioned in the review, that does not detract from the products perceived value. Would recommend to family and friends. 3 - Average product. Not exactly as described, or misleading advertising or product pictures. Possibly substandard build quality, or something else explained in the review. Would mention as an option to family and friends, but not recommend. 2 - Wouldn't recommend this product. Poor build quality, not close to being as described. Flimsy and fragile. Difficult to use due to product flaws. 1 - Do not purchase whatsoever. Usually only given if product lasts only a few hours/days/etc. I do not leave 1 star reviews without contacting the seller. I will be returning the product. I did NOT receive ANY discount for this product. I simply enjoy reviewing every one of my purchases. Review: Solid, square, and good quality so far. - I find myself needing a couple 2x4 scraps fairly often, to set parts on for hammering out stuck pins or shafts. That can be a wobbly headache, so I decided to buy these for stability, and versatility on heights. They've worked out well for that. Having holes allows me to position the pins & shafts over the holes, to tap out on just one block, or for bigger pieces, I can balance even odd shaped parts on the 2 blocks, using 1-3" varying heights, to stabilize & get a better angle on the pin. It's been very handy for me - used in this manner. As to the intended purpose, I have no idea. Pros: Smooth, no burrs, no rust. Straight edges, no wobble. Right angles, no tipping / variation. Feels heavy, & so far - no dents from hammer misses. : ) Cons: None, so far. Overall: They're a bit smaller than I'd like, but I wasn't willing to pop for anything bigger. They are what they say they are. ## Features - This matched pair of blocks is ground to tolerances of .0001". 23 holes, 5 tapped 3/8"-16 TPI and 18 plain - Precision ground and case hardened on all six sides - Squareness of all sides is within .0002 per inch. - Used for set-up, layout and inspection jobs ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07QWSL7TJ | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #29,221 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #3 in Dimensional Calibration | | Customer Reviews | 4.8 4.8 out of 5 stars (1,189) | | Date First Available | April 23, 2019 | | Item Package Quantity | 1 | | Item Weight | 2.02 pounds | | Item model number | BLOCK 123 | | Manufacturer | LLDSIMEX | | Material | Steel | | Part Number | BLOCK 123 | | Product Dimensions | 3 x 2 x 1 inches | | Size | 1" x 2" x 3" | ## Images ![Pair 1" x 2" x 3" Precision Steel 1-2-3 123 Blocks 23 Holes - Image 1](https://m.media-amazon.com/images/I/81E2Cd7Y7SL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very accurate *by S***Y on January 24, 2022* These are very accurate and there's not a whole lot to say because if you're buying this you know what they are for I personally depend very heavily on reviews that are posted on Amazon, as do many other consumers.

I’ve used them as machinist’s jacks, for squaring up stocks, as a vise stop and for other things as well. They were well worth the $ and I plan on getting another pair. ## Frequently Bought Together - LLDSIMEX Pair 1" x 2" x 3" Precision Steel 1-2-3 123 Blocks 23 Holes - Machinist Square Set 2, 3, 4, 6 Inch, Atarvana Mechanical Steel High Precision Square, Harden Carbon Steel Engineer Square, 90 Degree Wide Base Square, L-Type Right Angle Ruler Tool for Woodworking --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/140705473-pair-1-x-2-x-3-precision-steel-1-2](https://www.desertcart.pt/products/140705473-pair-1-x-2-x-3-precision-steel-1-2) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-05-31*
