1-2-3 Steel Setup Blocks 1"×2"×3" Matched Pair – 1 Hole
Precision 1-2-3 Steel Setup Blocks – Matched Pair with 1 Hole
Achieve workshop-grade accuracy with this matched pair of 1"×2"×3" precision ground steel setup blocks. Whether you're a machinist, metalworker, or woodworker, these hardened steel blocks are an essential shop tool for consistent, repeatable positioning, fixturing, and layout work on the mill, drill press, or workbench.
Why Choose These 1-2-3 Blocks?
- Precision Ground Steel: Manufactured from high-quality steel with accuracy-ground faces, ensuring flat, square, and parallel surfaces for reliable setups every time.
- 1 Hole Design (1/2" diameter): The strategically placed hole allows easy clamping, attachment of accessories, and versatile fixturing arrangements without sacrificing block strength.
- True Matched Pair: Both blocks are ground to the same exacting dimensions (1"×2"×3"), so they can be used together for symmetrical setups, parallel raising, and simultaneous referencing.
- Versatile Application: Ideal for milling machine setups, drill press work, surface plate layout, angle plate work, and woodworking jigs — a go-to reference block for any precision task.
- Compact & Stackable: The classic 1-2-3 size ratio means blocks can be stacked and combined in multiple orientations, giving you three different height references from a single pair.

Frequently Asked Questions
Q: What are 1-2-3 steel setup blocks used for in metalworking?
A: 1-2-3 steel setup blocks are precision ground reference tools used to position, raise, and align workpieces on mill tables, drill presses, and surface plates. Their three distinct face dimensions (1", 2", and 3") allow machinists and metalworkers to quickly establish accurate height, parallelism, and squareness in a wide variety of fixturing and layout setups.
Q: What is the hole size on these 1-2-3 blocks?
A: Each block features a single 1/2" diameter hole, which allows for easy bolt-through clamping, stacking with threaded accessories, and secure attachment to fixtures — adding versatility while maintaining the full structural integrity of the block.
Q: Are these blocks sold as a matched pair?
A: Yes! This listing includes one matched pair (2 blocks), both precision ground to identical 1"×2"×3" dimensions, so they can be used simultaneously on opposite sides of a workpiece for perfectly parallel and symmetrical setups.
Q: Can these steel setup blocks be used for woodworking as well?
A: Absolutely. While 1-2-3 blocks are a staple of metal machining shops, they are equally useful in woodworking for squaring up jigs, referencing router tables, setting up dado cuts, and ensuring accurate drill press positioning on wood workpieces.
