Steel Try Square MEGA 300 mm model 21130

MEGA steel try square 300 mm model 21130 is a precision layout and measuring tool designed for woodworking, metalworking and general construction. The square combines a 300 mm hardened steel blade with a robust steel body to provide reliable straight edges and accurate 90° reference for marking, checking right angles and verifying the squareness of components and assemblies. The tool is suitable for both workshop benches and jobsite conditions where a durable, stable square is required.

Advantages

The hardened steel blade and solid steel body deliver long-term edge stability and resistance to deformation. The 300 mm length offers a balance between reach and control for common workshop tasks. Machined mating faces ensure consistent 90° accuracy while the compact, all-steel construction tolerates routine handling and storage without compromising performance.

Suitable for

• Marking and scribing straight lines on wood and metal
• Checking and setting 90° angles on assemblies and parts
• Verifying squareness of frames, boxes and panels
• General layout work on workshop benches and construction sites

Key specifications

• Blade length: 300 mm
• Material: steel blade and steel body
• Edge type: hardened, machined straight edges
• Reference angle: 90° machined faces
• Intended use: workshop and site measuring and layout

How to use

Place the try square with the body firmly against the reference surface so the blade lies flat on the workpiece. Use the straight edge of the blade to guide a pencil or scribe for marking, or visually check the gap between the blade and the workpiece to assess squareness. For repeatable checks, align one face of the square to the reference and rotate the workpiece if necessary. Keep the mating faces clean and free of debris to maintain measurement accuracy.

Usage recommendations

Store the try square in a dry place and avoid drops or heavy impacts that could deform the edges. Periodically inspect and, if required, lightly clean the machined faces with a soft cloth; do not use aggressive abrasives. For critical precision work, verify the 90° angle against a calibrated square or surface plate before use.
