## Overview

The WEN 10423 1-2-3 Blocks set includes two hardened alloy steel blocks precisely machined to 3 x 2 x 1 inches with five threaded holes each, designed for accurate calibration, spacing, and measurement in machining and woodworking projects. Durable and versatile, these blocks provide professional-grade reliability and clamping strength favored by experts.

## Description

Remember when you could calibrate equipment, space workpieces, and collect exact measurements all with one tool? Maximize accuracy with the WEN 1-2-3 Blocks. With one side measuring exactly 1 inch, one side at exactly 2 inches, and a third side at exactly 3 inches, you’ll be able to ensure accuracy on every project. Made from heavy-duty hardened steel, the WEN 1-2-3 Blocks have been machined to be perfectly square, with 5 tapped holes (3/8-16 UNC) for bolting, drilling, hammering, or whatever else you need them for. This pack comes as a set of two, turning your 1-2-3 blocks into 4-5-6 blocks. Remember when you could have faith in your measurements? Remember WEN.

Review: Great value on a machinists staple - Quality hardened steel blocks, surface ground for parallel and square. Fit for purpose and use. Delivered on time in good condition.
Review: Very good blocks - Bought two sets, so four total. Cleaned them off with mineral spirits and some denaturated alcohol and measured all dimensions, and each end, with Mitutoyo calipers (precision to 0.0005"). They all landed on the 0 but depended on the pressure applied, meaning they are probably somewhere in their stated 0.0002" tolerance. The middles all dipped to X.9995" with the same pressure applied to the edges, but stayed at 0 with lighter pressure, so each of the blocks has a very mild dip in the middle, but that's ok. I also used a DIN 875/00 knife-edge reference square to check for square. They're good enough for wood working and some rough machining setups. Some corners were so good there was zero light leak. Others were off a bit. Definitely not ultra-precise blocks, but more than good enough for most needs, especially at this price point. Blocks like these make EXCELLENT clamping and square blocks for building boxes or other things where traditional full size woodworking clamping squares won't fit. They also won't flex or bend, so you can apply significant clamping pressure to use these to force tight joints into square.

### ⭐⭐⭐⭐⭐ Good value set of blocks.
*by A***N on October 30, 2025*

Some have noted problems with these blocks, but mine seem very good indeed!. The blocks are square, true, flat, and have a near mirror finish when you get the oil/grease off. These do come (like nearly all such tools) wrapped in oilcloth paper. Not as bad as cosmolene, but it does require degreasing followed by a proper waxing to preservw finish and prevent oxidation. The packaging is not great: just wrapped in the paper, then in a plastic bag, and finally in a light cardboard box. Just be sure to check for damage after cleaning the blocks. As stated, mine arrived in good shape. RECOMMENDED
