Helios Preisser metal engineer's try square 30 x 18 cm model 0375414

Helios Preisser metal engineer's try square 30 x 18 cm model 0375414 is a precision layout and checking tool for metalworking and woodworking. The try square combines a rigid metal blade with a solid metal stock to provide a stable reference for marking, checking 90° angles and verifying squareness of edges, joints and components. Its 30 x 18 cm blade and stock dimensions make it suitable for general workshop tasks where a robust, durable square is required.

Advantages

The metal construction ensures long-term dimensional stability and resistance to wear compared with wooden squares. A firmly fixed blade and accurately machined mating surfaces provide reliable right-angle accuracy for repeated use in layout, assembly and inspection. Its compact but substantial size balances portability with enough reach for most bench and machinery tasks, and the smooth surfaces make it easy to draw clear layout lines.

Suitable for

• Marking and scribing right angles on metal and wood
• Verifying squareness of machined parts and assemblies
• Setting up machinery and fixtures that require 90° references
• General workshop layout and inspection tasks

Key specifications

• Blade and stock dimensions: 30 x 18 cm
• Material: metal construction for blade and stock
• Type: engineer's try square for layout and angle checking
• Finish: machined mating surfaces for accurate right-angle alignment

How to use

Place the stock firmly against the reference edge of the workpiece so the blade lies flat along the surface to be marked or inspected. Use the blade edge as a straightedge to scribe or draw a 90° line, or visually check the gap between the blade and the workpiece to assess squareness. For inspection, rotate the square around the workpiece edges and reposition to confirm consistent alignment. When using with delicate finishes, protect surfaces or use light pressure to avoid marring.

Usage recommendations

Store the try square in a dry place and protect the blade from impacts to maintain accuracy. Periodically check the square against a known reference or a calibrated master square to confirm right-angle accuracy before critical measurements. Clean off debris and swarf after use to prevent wear on the machined surfaces.
