Square YATO YT-70771 stainless steel 1 pc, precision layout and angle measuring tool

The Square YATO YT-70771 stainless steel 1 pc is a precision layout and angle measuring tool designed for accurate marking, checking squareness and guiding cutting or assembly operations. Constructed from stainless steel with a 300 mm bevel and milled millimeter graduation, this single-piece square integrates a 45° and 90° measuring plane, a spirit vial for levelling, and an aluminum body secured with a brass locking screw. The included stylus aids in scribing and transferring measured lines, while corrosion-resistant materials ensure long-term dimensional stability and repeatable results in workshop and site conditions.

Advantages

The stainless steel construction offers corrosion resistance and straight, wear-resistant edges for reliable measurement transfer. The milled millimeter graduation on the 300 mm bevel delivers clear, precise readings and helps reduce marking errors. Built-in 45° and 90° measuring planes combined with a spirit vial allow both angle verification and basic levelling checks with a single tool. The aluminum body, locked by a brass screw, provides a stable connection and helps maintain alignment under normal workshop use. The included stylus facilitates accurate scribing directly from the scale.

Suitable for

• Carpentry layout and marking of boards, panels and frames
• Metalworking tasks requiring square checks and angle transfers
• Construction site marking and on-site assembly verification
• Guiding saws, routers or chisels during joinery and fitting work

Key specifications

• Material: stainless steel blade with aluminum body
• Bevel length: 300 mm with milled millimeter graduation
• Measuring planes: 45° and 90°
• Level: integrated spirit vial
• Fastening: brass locking screw for body connection
• Accessories: included stylus for scribing

How to use

Place the square with its reference face against the workpiece edge to transfer a right angle or the 45° reference. Read the milled millimeter graduation on the 300 mm bevel to mark distances directly from the tool, and use the included stylus to scribe lines precisely along the blade. Use the spirit vial to check simple levelling where required. Tighten the brass locking screw if any adjustment is needed to secure the aluminum body before performing repetitive layout tasks.

Usage recommendations

For best accuracy, rest the square on a clean, debris-free edge and verify the blade is free of nicks or burrs. Store the tool dry to preserve the stainless steel finish and periodically check the locking screw for tightness. Use the stylus on softer marking surfaces and avoid excessive force that could deform the blade or body.
