## Long description

MEGA steel square model 21030 is a 300 mm precision layout and angle-checking tool made of steel. Designed for marking, measuring and checking right angles in woodworking, metalworking and construction, it provides a rigid straight edge and a stable 90° reference for accurate transfers, scribing and verification of squareness on workpieces and assemblies. The compact 300 mm size balances portability with a long enough blade for common workshop and site tasks.
Advantages
The steel construction ensures durability and a consistently straight reference edge that resists bending under normal use. The machined joint between blade and stock maintains a reliable 90° angle for repeated checks. Its 300 mm blade provides sufficient reach for many cabinetry, joinery and metal fabrication tasks while remaining easy to handle. The tool's simple form and solid build make it suitable for both quick checks and precise layout operations.
Suitable for
 Marking and scribing right angles on wood and metal
 Checking squareness of assemblies, frames and panels
 Transfer of reference lines and layout work in workshops and on-site
 Use with saws, routers and machining setups to set fences or stops
Key specifications
 Material: hardened steel construction for a stable straight edge
 Length: 300 mm blade suitable for general layout and measuring tasks
 Angle accuracy: fixed 90° reference between blade and stock for squareness checks
 Design: one-piece steel square with machined mating surfaces for repeatable alignment
How to use
Place the stock of the square firmly against the reference face of the workpiece so the blade lies flat on the surface to be marked or checked. For marking, use the blade as a guide to scribe a line along its edge with a knife, pencil or scriber. For checking squareness, align the stock against one face and inspect the blade edge against the adjoining face; any gap indicates deviation from 90° and can be measured or adjusted accordingly. Use light clamping where necessary to prevent movement during layout or marking.
Usage recommendations
Keep the steel square clean and free of burrs or built-up material to maintain accuracy; store it in a dry place and avoid dropping or striking the edges. For precision work, verify the square against a known reference periodically and avoid using excessive force that could deform the blade or stock.
