JessEm Imperial Stainless Steel Precision Squares with Flex Grip

These innovative squares from Jessem are packed with features not found on any other precision squares.

A standout feature of these squares is the patented Flex Tabs, designed to maximize grip on virtually any surface softer than the steel itself, preventing slippage when marking or scribing on materials like wood, metal, composites, paper, and more.

Each square includes a balancing tab that easily extends from the base and locks into position, allowing you to balance and scribe across your workpiece with ease. This extended balancing tab keeps the square level and registered against your material hands-free, without needing to hold it in place. When not needed, the tab can be retracted.

Scribing holes are precisely spaced every 1/16" for drawing perfect, accurate parallel lines across your workpiece.

The blades are crafted from 301 hardened stainless steel and feature quick-read 1/32” graduation marks that are etched and then laser-engraved, ensuring durability under the rigors of daily use. Graduation marks are located on both the inside and outside edges of the blade, on both sides, for added convenience. The bases are made from CNC machined anodized aircraft aluminum, and the blades are securely fastened to the base with four stainless steel hex screws.

Each square undergoes rigorous quality control testing to ensure you receive only the most accurate measuring tool available. Graduation markes are withing 0.004" and every square is calibrated to be square within 0.002" over the length of the blade. If the blades ever get knocked out of square, they can be reset.

These squares are perfect for woodworking, drafting, metal working, art, design and more and with a range of sizes, you always have the perfect ruler for every project.

Each square comes fitted in a handy MDF storage/presentation block.
