Frequently bought together:


Like perfect minions, these squares are compact, come in sets, and are ready to hold your work when summoned.

These squares come in a compact configuration for use in tight spaces. Each square measures 6" x 4" x 1.5", the 4" width is perfect for picket spacing on gates and fences. They are the first square we offer which has a built in 60/30 degree angle. The cutout also provides just the right amount of joint access when using it to clamp things at 90 degrees.

Bosses on the square allow mounting of tabs to both sides of the tool.  

Squares are sold as a "left and right" pair, each pair will come with 2 squares, 8 tabs, 8 thumbscrews.


Compact Size For Tight Spaces

4" Width Perfect For Picket Spacing

Clamp The Angles Together To Create Custom Spacing

Cast Iron vs Aluminum


Cast Iron


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


  • Heavier



  • 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.

Included Accessories

4 Edge Location Tabs

Each square comes with 4 of our new compact tabs measuring 1-3/4" (1.75) long x 5/8" (0.625) wide, and 4 of our newly designed thumbscrews to provide tool-less adjustment of tabs.

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!

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.

Our Other Squares

  • The Mega Square is designed to quickly set your workpiece to 90 or 45 degrees.
  • Tabs help eliminate twisting and warping in the final workpiece.
  • Clamping is simple with multiple surfaces for quick and rigid attachment.
  • Roomy joint access for welding, gluing, nailing, riveting, etc.
  • The original Monster Square is available in a 12 or 8 inch size with two material choices.
  • The Monster Square is designed to quickly set your work piece to 90 or 45 degrees.
  • Clamping is simple with multiple surfaces for quick and rigid attachment.
  • Use the radius on the tabs to use the Monster Square as a traditional speed square for layout.
  • Use it as an ordinary, adjustable angle square that adjusts from 40 to 180 degrees.
  • Right Angle 90 Degree Square with generous weld accessibility. Total height of 8” in this configuration.
  • Tall 12” square when fully opened and locked into place
  • Remove the fasteners to get two individual squares
  • Use the large V-groove to hold large round tubing or pipe

    Awesome little tools !

    Posted by eric johnson on Jul 7th 2020

    Third set of squares I have ordered so have all sizes for any project. Have used for everything from building trailer sides , mesh trailer boxes and stake bed sides from tubing and expanded metal. Work in small welding shop and get used often! I went with the aluminum since I am often clamping vertically Thank you for such a great tool ! I am a retired army engineer and not new to maintenance or welding If your looking at these just buy them you will not regret it

    Perfect for Home...

    Posted by Nicholas Johnson on Jun 23rd 2020

    I weld a lot of tables and stands in my little one-car garage and these make setting up right-angles a breeze! The concrete on my floor isn’t flat, so I use these as my reference and everything I’ve welded with them so far hasn’t had any wobbles once complete! I’ll probably buy another pair on the future just to make the setup and welding process even faster! I definitely recommend!

    Accurate 90’s, handy size; “black oxide” finish...

    Posted by Michael Zucker on Jun 23rd 2020

    The minion squares work great, paired use as an adjustable parallel or jack is an unusual bonus.

    I was a little disappointed in the quality of the thumbscrews/hardware supplied; very loose threads, heads not faced perpendicular, and the knurling looks like it was done with a pair of vise-grips.

    Also the “black oxide” finish rubs off and makes a mess, even after several wipedowns. What remains on the tool is splotchy and uneven. A true oxpho or hot steam blackening would not rub off; this behaves almost like an oily dye.

    If real blackening is not economical, consider just going with clean cast iron; properly oiled and cared for, the corrosion and spatter resistance of grey iron are fully adequate.

    All that said, the tools function well, and after I bead blast the black stuff off and replace all the hardware I will be happy to have them in my box.
