Angle Surface Square Beta Tools 1670/300 flat surface square 300 mm

Flat surface angle square Beta Tools model 1670/300 is a 300 mm precision layout and measuring tool for marking and checking right angles on flat surfaces. Designed for workshop and industrial use, it provides a reliable 90° reference and a straight edge for scribing, aligning and measurement tasks. The square is suitable for use on metal, wood and composite materials where accurate perpendicular alignment and repeatable layout are required.

Advantages

The Beta Tools 1670/300 flat surface square offers a durable construction and a stable reference edge that resists wear during repeated use. Its 300 mm length gives a balance between reach and control, enabling precise marking and inspection across typical workpieces. The tool’s flat, machined faces ensure consistent contact with the work surface, reducing cumulative error when transferring or checking right angles.

Suitable for

• Marking and scribing right angles on metal plates and sheets
• Checking perpendicularity in assembly and fabrication
• Layout and squaring of wooden components in carpentry
• Quality control and inspection where a true 90° reference is required

Key specifications

• Total length: 300 mm measuring edge
• Type: flat surface angle square for 90° layout
• Contact faces: machined flat faces for stable seating
• Construction: robust metal body designed for workshop use
• Primary function: marking, aligning and checking right angles

How to use

Place the square with its inner corner against the reference edge or surface so both contact faces sit flat. Use the straight edge to scribe or mark the workpiece at the required location, keeping steady contact to avoid parallax. For inspection, align the square against the part and visually or instrumentally check for gaps or misalignment along the contact faces. Where repeated measurements are needed, reposition the square consistently from the same datum to maintain repeatability.

Usage recommendations

Keep the machined faces clean and free of burrs or debris to preserve accuracy; store the square in a protective location to avoid knocks that can deform the edges. When high-precision verification is required, compare the square against a certified reference and follow routine calibration or inspection schedules appropriate for workshop tools.
