More questions buyers ask
What is a hardened and ground try square used for?
A hardened and ground try square is a precision woodworking or metalworking tool used to check for and mark 90-degree angles on workpieces. The hardening process ensures durability and resistance to wear.
What material is the Crystal try square made from?
The Crystal try square is constructed from high-quality, hardened and ground steel to ensure maximum accuracy and a long service life in a workshop environment.
Is the Crystal try square suitable for professional workshop use?
Yes, its robust construction and precision-ground faces make it an essential and reliable tool for professional machinists, fabricators, and quality control inspectors.
How do I maintain the accuracy of my try square?
To maintain accuracy, avoid dropping the tool, keep the edges clean and free of burrs, and store it in a protective case or a dry place to prevent rust. Periodically check it against a known master square.
Does the try square come with a warranty?
Yes, we offer a standard 1-year warranty against manufacturing defects. Please contact our customer service for more details.
Is this try square available in different sizes?
Yes, the Crystal AA-410 series is available in a wide range of sizes, from 50x30mm up to 400x250mm, to suit various application needs.
What is the accuracy of the Crystal try square?

Can I get a GST invoice for my purchase?
Absolutely. We provide a GST invoice for every purchase, which is essential for businesses claiming input tax credit.
Do you offer delivery across India?
Yes, we offer pan-India delivery to all major cities and industrial areas. Your order will be safely packaged and shipped to your location.
Is the try square resistant to rust?
The steel construction has some natural resistance, but to prevent rust, it is recommended to keep the tool lightly oiled and stored in a dry environment.
Who should choose the Crystal AA-4101 (50x30mm) try square?
The AA-4101 is ideal for small-scale, high-precision tasks, such as model making, jewelry, or inspecting small machined parts where a compact and lightweight square is required.
Who should choose the Crystal AA-4102 (75x50mm) try square?
The AA-4102 is a versatile mid-range size, perfect for general workshop use, small fabrication projects, and checking the squareness of smaller components and assemblies.
Who should choose the Crystal AA-4103 (100x70mm) try square?
The AA-4103 offers a good balance of size and reference length, making it suitable for both benchtop work and larger fabrication jobs that require a sturdy and reliable square.
Who should choose the Crystal AA-4104 (150x100mm) try square?
The AA-4104 is a popular choice for general metalworking and woodworking, providing a long enough edge for marking and checking medium-sized components with confidence.
Who should choose the Crystal AA-4105 (200x140mm) try square?
The AA-4105 is designed for larger scale projects, such as frame assembly, machinery setup, and sheet metal fabrication where a longer reference surface is crucial for accuracy.
Who should choose the Crystal AA-4106 (250x165mm) try square?
The AA-4106 is suited for large fabrication and assembly tasks. Its significant size provides an excellent reference for ensuring large frames and structures are perfectly square.
Who should choose the Crystal AA-4107 (300x200mm) try square?
The AA-4107 is one of the largest options, ideal for heavy-duty industrial applications, large-scale welding projects, and machine alignment where precision over long distances is key.
Who should choose the Crystal AA-4108 (400x250mm) try square?
The AA-4108 is the largest in the series, intended for major industrial fabrication, large machine tool setup, and any application demanding the highest level of accuracy over a substantial length.
What is the main difference between the smaller and larger Crystal try squares?
The primary difference is the length of the blade and stock. Smaller squares are for fine, detailed work on small parts, while larger squares are for checking and marking bigger assemblies and fabrications where a longer reference edge is needed.
How do I choose the right size of try square for my needs?
Consider the typical size of the workpieces you handle. The square's blade should be long enough to span the surfaces you need to check. For a versatile workshop, having both a small and a large try square is often recommended.
Are the larger models like the AA-4108 as accurate as the smaller ones like the AA-4101?
Yes, all Crystal try squares, regardless of size, are manufactured to the same high standards of precision and accuracy. The larger models provide that accuracy over a longer distance.
Is there a price difference between the various sizes?
Yes, the price increases with the size of the try square. Larger models require more material and manufacturing precision, which is reflected in their cost. You can see the specific price for each size on our product page.
