Corner Square Helios Preisser 15 x 10 cm model 0375408 — metal try-square for workshop measurements

Helios Preisser corner square model 0375408 is a compact metal try-square with blade dimensions of 15 x 10 cm designed to provide a rigid 90° reference for precise right-angle measurements. Built for workshop use in metalworking and woodworking, this tool is intended for marking, checking squareness of edges, aligning parts and verifying fixtures where a small, durable square is required.

Advantages

The metal construction ensures stability and resistance to deformation during repeated use, while the compact 15 x 10 cm size offers portability and easy handling in confined spaces. The square provides a clear, accurate reference for marking and inspection tasks and is suitable for both layout and quality-control routines. Its simple geometry and solid build reduce the need for frequent recalibration under normal workshop conditions.

Suitable for

• Marking and scribing right angles on metal and wood
• Checking squareness of edges, joints and assembled parts
• Setup and alignment tasks on benches, jigs and fixtures
• Small fabrication, repair and hobby workshop tasks
• Quality control checks during assembly and finishing

Key specifications

• Blade size: 15 x 10 cm (approximate usable faces for measuring and marking)
• Material: metal body for rigidity and wear resistance
• Angle: precise 90° reference for right-angle measurements
• Form factor: compact, hand-held try-square suitable for confined spaces
• Application environment: workshop use for metalworking and woodworking

How to use

Place the stock of the try-square firmly against the reference edge of the workpiece so the blade lies flat on the surface to be marked or checked. Use the blade edge as a guide to scribe lines or to visually verify that adjoining surfaces meet at a true 90°. For alignment, hold the square steady and adjust the workpiece or fixture until the blade and faces show no gap along the joint. When measuring thickness or small offsets, use the blade faces as the contact surfaces and read off marks made with a pencil or scriber.

Usage recommendations

Handle the metal try-square with care to avoid drops that could dent edges and reduce accuracy. Store the square in a dry place and protect it from corrosive liquids. For best results when scribing, ensure the reference edge of the workpiece is clean and free of debris; periodically inspect the square for nicks or wear and replace if accuracy is compromised.
