Combination square is an essential tool for carpenters, machinists and builders. It is a convenient blend of a ruler and a right-angled headstock. Hence, this marking tool boosts measurements for both length and angles. Starrett combination square set eases tasks like marking cut lines, checking right angles and measuring depths. For instance, woodworking helps craftsmen create precise joinery, while metalworkers rely on it for accurate measurements during fabrication. This tool combines the features of a ruler and a protractor to make accurate measurements.

Assemble Combination Square in Just 5 Steps

1. First of all, align the bolt with the groove when putting the blade into the head.
2. If the bolt is not in the right place, loosen the spring-loaded lock nut.
3. Then, press down and turn the post until the bolt aligns with the blade slot.
4. Finally, slide the blade into the head and secure it by locking the nut.
5. Repeat the same steps for attaching square and protractor heads.

Also, the blade has two or four graduations along its edges. So, to switch and view different graduations:

• Loosen the nut and remove the blade.
• Rotate the bolt 180°, flip and re-insert the blade, then lock the nut.

How to Use Combination Square?

With the Square Head

• First, ensure that the combination square is clean and in good condition.
• Tighten any locking screws to secure the square head in the desired position along the blade.
• Next, clamp the material on a flat and stable surface.
• Place the combination square against the edge of the material where you need to make a mark.
• Then, align the square head precisely with the edge of the material.
• Also, ensure that the combination square is firmly held in place.
• At last, use the included scriber to make a clear and precise mark along the edge of the square head.

With the Protractor Head

• If you need to mark an angle, first loosen the locking screw on the protractor head.
• Then, set the protractor head to the desired angle by aligning it with the markings on the ruler.
• Keep the material securely in place on your work surface.
• Next, position the combination square with the protractor head against the material, aligning the blade with the reference edge.
• Ensure that the combination square is stable and well-supported.
• Now, use a pencil or the included scribing tool to make a precise mark at the desired angle.

Pro Tips:

• Double-check measurements and angles before making any marks to avoid errors.
• Apply consistent and gentle pressure when making marks to maintain accuracy.
• Regularly check and calibrate your combination square set to ensure accurate measurements.
