Toledo Engineering Square – Graduated Metric & Imperial 150mm

The Toledo SSA6G Engineering Square is a precision measuring and layout tool designed for professionals who demand accuracy and versatility. Combining the function of a traditional try square with the utility of a rule, this 150mm (6″) tool features a fully graduated blade with clear Metric and Imperial markings. Whether you are marking out joinery, setting up machinery, or verifying right angles on a fabrication project, the dual-scale graduations allow for simultaneous measuring and squaring, saving time and effort in the workshop.

Manufactured to strict BS 939 Grade B standards, the square is constructed from hardened stainless steel to resist corrosion and wear. The blade is permanently secured to the stock using tapered self-locking rivets, ensuring a rigid, movement-free bond that maintains its perpendicularity over years of use. Both the blade and stock are precision ground and lapped for straightness, while a dedicated groove on the inner corner allows for the clearance of burrs and debris, ensuring a flush seat against your workpiece every time.
