Frame squares, also called framing squares and steel squares, are an essential tool in carpentry and framing. They are used to layout and measure a variety of angles and cuts. Frame squares are L shaped, with two arms that are joined together at an angle of 90 degrees. They have a number of uses, including marking straight lines on wood, scribing, and measuring angles accurately.

When using a frame square, the longer arm is used to mark the length of the material while the shorter arm, known as the blade, is used to mark the width of the material. To use the frame square, measure the length of the arms, then use this measurement to mark the desired length and width of the material. It is important to make sure that the markings are level with each other so that the angles are accurate.

Frame squares can also be used to mark angles on wood and other materials. The most common use for the frame square is to measure angles of 45 degrees and 90 degrees. To mark a 45 degree angle, the hypotenuse of the frame square is placed against one edge of the material and the blade is placed along the opposite edge. To mark a 90 degree angle, the hypotenuse is placed against one edge of the material and the longer arm is placed against the opposite edge.

Frame squares are also used for scribing, which is the marking of lines along the edge of the material. In order to do this accurately, the rod of the frame square should be aligned with the edge of the material. The blade of the frame square can then be used to draw a line along the length of the edge.

Using a frame square is a simple but effective way to get accurate results when marking angles and lines on wood and other materials. It is an inexpensive and useful tool for any woodworker or carpenter.
