Description


The original Mega Square is available in a 12 or 8 inch size with two material choices: Cast Iron (FE) or Cast Aluminum (AL). All Mega Squares feature a stiff “flange and web” design that is fully machined on all outer edges with tapped holes on the sides for mounting tabs.

Made In USA - Patent Pending

Roomy joint access for welding, gluing, nailing, riveting, etc.

Whatever process you’re working with, it probably benefits from some clearance around the joint.

Tabs help eliminate twisting and warping in the final work-piece.

The machined squares and tabs always create the perfect plane for your work-pieces to rest on. Tabs also let you easily hold round tubing.

Clamping is simple with multiple surfaces for quick and rigid attachment.

Stop spending your time and focus figuring out clamping strategies, or worse, clamping your straight workpiece to crooked surfaces.

Perfect For Angle Iron

Designed to quickly set your work-piece to 90 or 45 degrees. Speed squares and machinist squares are made for visual inspection and checking AFTER setup, the Mega Square is designed to get those parts square in the first place.

Flange & Web

  • 12” squares have a profile similar to an I Beam where the web is centered on the flanges.
  • 8” squares are similar to a “C” channel where the web is off to one side of the flange.
Customer Reviews

"Awesome squares. I also ordered the extra tabs. I use them constantly as my worksuraces are all slightly bent. These squares fix that as it's the contact with the material and the squares that render the work surface defects moot! I will be buying more possibly the minions but definently the angle squares I really need those. I'm an artist so I get crazy angle request."

"I've been fabing a few years now, and just recently started to do bigger projects, and haven't made the investment into a proper fab table yet. And I can tell you this is must have if you don't have a fixture table. But the great thing about fireballs squares are that if you do a Fab table then these are great addition to it! You can start with these at a lower entrance fee and make more money with better quality and increased production speed, and then get your table and continue to use them with even greater versatility. I picked up a 12" aluminum Mega Square, and I'm already planning on getting the 12" Monster Square. And I personally went with the 12" over the 8" because the larger squares are able to work on smaller projects as well as the big ones."

Aluminum vs Cast Iron

Cast Iron

Pros

  • Great for heavy duty projects
  • Excellent resistance to deformation and raising burrs when scratched.
  • Some natural resistance to weld spatter.

Cons

  • Heavy (Not ideal for mobile welding)
  • Susceptible to rust.

Aluminum

Pros

  • Lightweight (Ideal for welding on the go)
  • Resistance to deformation vs aluminum billet
  • Some natural resistance to weld spatter.

Cons

  • Can be be damaged if dropped or if used in heavy duty projects.

Included Accessories

4 Edge Location Tabs

Our revolutionary tabs allow you to align your material up so that you don’t even need a welding table! Don’t spend thousands on a flat table, just use our squares! Tighten the tabs onto the front or back of your square and you can immediately get to work. Sure, there are different jigs out there, but can they line your material perfectly in seconds?

4 Tool-less Thumbscrews

But it doesn’t stop there. We reinvented the game by introducing our thumbscrews. Say goodbye to your hex keys and Allen screwdrivers and freely adjust the tabs with only your fingers!

Optional Add-ons

Edge Alignment Pins

Install our edge alignment pins on any square to create a large, overhanging edge which can be used to index the square on a different plane. Depending on the square, this allows you to create edges which are 90 degrees (perpendicular), 45 degrees, parallel, and even 60 and 30 degrees from the edge.

  • Use it with our Monster squares to create a speed square for layout.
  • Use it to hang the square off the edge of a table for working vertical or perpendicular to table surface
  • Use it to elevate the squares off the ground or table for extra clearance when you’re fitting and welding entire frames
  • Tip! If trying to create a parallel edge with the mega square for marking, use our shims to get that perfect distance!

Optional Back Oxide Coating

What is Black Oxide?

Black Oxide, blackening, oxidizing, oxiding, black passivating, gun bluing . . . these terms all refer to the process of forming a black iron oxide on the surface of ferrous metals.

The black oxide process is a chemical conversion coating. This means that the black oxide is not deposited on the surface of the substrate like nickel or zinc electroplating. Instead, the black oxide coating is produced by a chemical reaction between the iron on the surface of the ferrous metal and the oxidizing salts present in the black oxide solution. These oxidizing salts include penetrates, catalysts, activators and proprietary additives which all take part in the chemical reaction. The result of this chemical reaction is the formation of black iron oxide, magnetite (Fe3O4), on the surface of the metal being coated. Black oxide has a range of unique properties and benefits including corrosion protection & reduced friction.
