Product Features
- A perfect range of Steel Square which conforms accuracy as per BS 939 Grade B for squareness.
- Hardened spring steel blades are fixed to the stock with self-locking tapered rivets to insure permanent accuracy. Both blades and stocks are precision ground for straightness and parallelism, and working edges of the blades are lapped straight within three ten thousandths of an inch, deviating from square by no more than .00063″.
- Non Scale marks on the both sides, used mainly in woodworking, to lay out cutting lines at 90-degree angles.
