Measuring tool STANLEY Combination Square 0-46-151, multi-angle layout and ruler guide

STANLEY Combination Square 0-46-151 is a precision hand measuring and layout tool designed for marking, checking 90° and 45° angles, and serving as a straightedge and depth gauge. The tool combines an adjustable cast-iron head with a sliding ruler etched with both metric and imperial graduations, enabling repeatable measurements and straightforward transfer of reference lines in carpentry, metalworking and general workshop tasks.

Advantages

The cast-iron professional head is machined on all faces for accuracy and long life, providing Class I precision. The blade is etched with metric graduations in millimetres and centimetres and imperial graduations in inches with 1/8 and 1/16 subdivisions. This combination square functions as a try square and mitre square, a depth or height gauge and can be used as a straightedge for layout work.

Suitable for

• Marking and checking 90° and 45° angles in woodworking
• Transferring measurements and scribing straight lines
• Setting and checking heights and depths on workpieces
• Metalworking layout and shop bench tasks
• General inspection and layout where Class I accuracy is required

Key specifications

• Ruler length: 300 mm (12")
• Blade graduations: metric (mm and cm) and imperial (inches with 1/8 and 1/16 subdivisions)
• Head material: cast iron, machined on all faces
• Accuracy class: Class I
• Functions: try square, mitre square, depth/height gauge, straightedge

How to use

Loosen the locking screw on the adjustable head to slide the ruler to the desired position, then tighten the screw to secure the measurement. For 90° or 45° checks, align the head against the workpiece and use the ruled edge to scribe or mark the line. Use the square as a depth or height gauge by setting the ruler to the required distance and locking the head before transferring the measurement. The etched graduations allow direct reading in either metric or imperial units.

Usage recommendations

Store the combination square in a dry place to prevent corrosion of the ruler; periodically check and recalibrate against a certified square when high precision is required. Use gentle tightening of the locking screw to avoid wear on the sliding surfaces and ensure consistent repeatability.
