Set square Staples 8.5 cm 45° – drawing and measuring tool

Staples 8.5 cm 45° set square is a compact drawing and measuring tool with a fixed 45-degree angle. Designed for precise angle marking, technical drawing, drafting and school use, it fits in pencil cases or tool kits. Its small size makes it convenient for on-the-go tasks, geometry exercises and basic layout work.

Advantages

The rigid construction ensures stable, repeatable markings at 45° while the compact 8.5 cm form factor offers portability and easy storage. Transparent or lightly tinted material provides clear visibility of underlying surfaces for accurate alignment. The simple, single-angle design reduces complexity for beginners and speeds up routine tasks for experienced users.

Suitable for

• School geometry exercises and classroom use
• Technical drawing, drafting and sketching
• Quick on-site marking and small layout jobs
• Pencil case or kit for students, architects, designers

Key specifications

• Fixed angle: 45 degrees
• Overall length: 8.5 cm
• Material: rigid transparent plastic
• Form factor: compact, pocket-friendly

How to use

Place the set square on the drawing surface with the desired edge aligned to an existing line or point. Hold the tool firmly with one hand to prevent slipping and draw the perpendicular or 45° line with a pencil, pen or fine marker along the free edge. For repeated measurements, use the set square as a guide to transfer the 45° angle from one location to another. When measuring small distances, align the tool’s edges with reference points and read visually; combining the set square with a ruler improves linear accuracy.

Usage recommendations

Store the set square in a pencil case or protective sleeve to avoid edge damage. Clean with a soft cloth and mild detergent if necessary. Avoid exposing the plastic to high heat or heavy pressure that could deform the angle. For precision work, pair the set square with a calibrated ruler or scale.
