Product Details:
- Starrett 11MH-300 is a 2-piece combination square set comprising a 300-mm-long, machine-divided, tempered steel blade / ruler and a cast-iron square head having black wrinkle finish. The components of this set are interchangeable so it can also be used with a longer ruler / blade, and a centre / protractor head to suit various applications.
- The square head has a precision ground, 90° square face and a 45° miter face. It can be used as a layout tool for scribing right angles and parallel lines, and as a tri-square, miter, depth gage, height gage and level for various measuring applications.
- This combination square set by Starrett features a reversible lock bolt, scriber and spirit level. The reversible lock bolt ensures proper alignment of the blade with the heads and enables the blade to be turned over without removing the lock bolt or nut.
