The FastCap Mag Square 45 Degree Magnetic Micro Square is a steel setup square made for accurate saw and equipment adjustment. This is a magnetic micro square designed for setting blades, spindles, and fences to a precise 45 degree angle. Model Number: MAG SQUARE 45 DEGREE. If you do finish carpentry, cabinet work, or routine shop setup, this tool cuts out the usual guesswork and gets you to a repeatable setting faster.

What matters most here is speed and consistency. Instead of sneaking up on a 45 degree setting with repeated test cuts, the FastCap Mag Square 45 Degree Magnetic Micro Square gives you a fixed reference you can trust. That is the real value on the job or in the shop. You spend less time adjusting and more time cutting, and you are less likely to burn material because the angle was just a hair off.

The magnetic base is the feature that makes this square more useful than a basic setup triangle. It sticks firmly to cast iron or metal tables, which means the square stays where you put it while you adjust the blade, spindle, or fence. Hands-free setup is not just convenient. It makes the process more controlled, especially when you are working on a table saw or other metal-top equipment where one hand usually ends up trying to hold a gauge in place.

FastCap also builds a scale right into the square, so this is not limited to angle setup alone. You can use it to set blade height and handle precision layout tasks where a compact, rigid reference is more useful than a larger framing or combination square. For finish carpentry, that makes it handy around trim work and other detail-oriented setups where small measurement errors show up fast.

The construction is steel, which is what you want for this kind of tool. A setup square needs to stay stable, stay straight, and hold up to regular contact with saw tables and shop surfaces. At about 0.35 pounds, it is light enough to keep nearby without adding clutter, but it still has the solid feel you want from a layout and machine setup tool.

This is best suited to woodworkers, finish carpenters, cabinet installers, and anyone who spends time tuning saws and shop equipment. It is especially useful for users who value repeatable machine setup more than a multi-purpose measuring tool with a bunch of moving parts. If your work depends on clean miters, accurate bevel settings, and quick adjustments on metal-top saws, this is a straightforward tool that earns its place.
