All Squares Come In Cast Iron Or Aluminum Options


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


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

Cast Iron


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


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

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?

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!

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!

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.
