Aanslaghaak met basis Helios Preisser 40 x 23 cm model 0374416

Helios Preisser squaring angle with base model 0374416 is a metalworking squaring tool with overall measuring faces of 40 x 23 cm designed for checking and transferring right angles. The rigid base provides stable support for precise squaring, marking and measurement tasks in fabrication and assembly. It is suitable for use in metal and wood workshops where reliable 90° reference and alignment are required.

Advantages

The solid, flat faces ensure consistent contact with workpieces and reduce play when checking perpendicularity. The integrated base keeps the tool stable on flat surfaces, allowing accurate layout and marking without additional fixtures. Constructed from tool steel with machined edges, this squaring angle resists deformation under normal workshop use and maintains its geometry for repeated checks. Its clear, rectangular shape simplifies alignment across edges and surfaces.

Key specifications

How to use

Place the squaring angle flat on the reference surface with the base resting fully on the bench or machine table. Bring the mating edge of the workpiece into contact with the squaring face and check for gaps along the joint; mark directly along the edge or scribe from the face for transfer of a true 90°. For verification of assembled parts, hold the tool against the reference surface and observe fit or use feeler gauges where small gaps must be quantified. When marking long edges, slide the tool along the surface while maintaining firm contact with the base to preserve perpendicular alignment.

Recommendations

Keep the machined faces clean and free of nicks; store the squaring angle in a dry place to avoid corrosion. For best accuracy, avoid dropping or using the tool as a striking surface. Periodically check the faces on a known reference square or surface plate and, if necessary, have the tool reconditioned by a qualified service to maintain precision.
