Internal & External Squareness as per BS 939 Grade B
An excellent range of precision steel squares that are second to none
These are useful for setting up & checking jobs where extreme accuracy is required
Hardened spring steel blades are permanently fixed to the stock by means of tapered self locking rivets which ensure complete rigidity.
Both the blade and stock are precisely ground to ensure straightness and parallelism. Working edges of the blades are lapped which further enhances accuracy
A groove on the inner corner of the stock aids in the clearance of burr or dirt
