Engineering Try Square

An engineering try square is a precision tool used primarily in metalworking and engineering to check the straightness and squareness (90° angles) of surfaces and components. It's similar in appearance and function to a carpenter’s try square but is built to much higher tolerances for accuracy.

Key Features:

1. Blade (or Beam): The longer arm, typically made of hardened steel for durability and precision.
   
   
2. Stock (or Handle): The shorter, thicker arm—usually also steel or sometimes cast iron—set at exactly 90° to the blade.
   
   
3. No graduations: Most try squares don’t have measurement markings (unlike combination squares or rulers).
   
   
4. Precision ground: Both inside and outside edges are ground to ensure high accuracy, often to within 0.01 mm or better.

Uses:

• Checking if a surface or edge is at a perfect right angle (90°) to another.
  
  
• Scribing perpendicular lines on workpieces.
  
  
• Verifying the squareness of machine setups or parts during machining, welding, or fabrication.
