Both sides of the satin finish chromium plated CB600-35 600mm hardened steel blade are photo engraved with full mm and ½ mm on both sides.
Starrett's chrome plating is rather more than just a surface finish, it is a thick, full-process, deep plating that is highly resistant to corrosion and wear. This makes it easier to read and you never need to worry about rusty fingerprints, oiling it before you put it away and so on.
They grind the blade thinner to account for the thickness of the plating so that the item will be accurate in it's finished state, then finish the finish to produce a high contrast low glare surface.
This makes it easier to read and you never need to worry about rusty fingerprints, oiling it before you put it away and so on.
It is compatible with all standard Starrett combination square components (excluding the smaller Junior series and larger 8 series Combination Squares) and is straight to better than 0.001" per foot.
