• 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.

• These squares come in a compact configuration for use in tight spaces
• Each square measures 150mm x 100mm x 38mm, the 100mm 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.
• Bosses on the square allow mounting of tabs to both sides of the tool.

• The original Monster Square is available in a 300mm or 200mm 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.

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.
