Heavy Duty Tri-Square 4 in

Note: Design, Colour and Brand may vary in each lot.

The engineer's try-square is composed of two parts, the stock, and the blade. They are usually made from bright mild steel with the blade being hardened and tempered so that it resists damage. A typical use of an engineer's try-square is to mark out material for cutting/shaping. A machinist square or engineer's square is the metalworkers' equivalent of a try square. It consists of a steel blade inserted and either welded or pinned into a heavier body at an angle of 90°.  This prevents small particles from accumulating at the juncture and affecting the square's reading.

• This square is made out of steel stock and a hardened blade.
• The blade is fixed to the stock by tapre pins.
• All faces are precision ground.
• It is used to check for squareness or to mark out the body of the workpiece.
• All Squares are ground to ensure they are straight and Parallel.
• The Beam is grooved at the inside Corner for Clear Clearance of Saw Dust or dirt.
