Combination Square Set, 6" 4R 

6" combination square set with square head and centering head and blade.

These squares are used by mechanics, toolmakers and patternmakers because of their compact, small size and light weight. Both blade and heads are smaller than on regular squares. Heads are drop forged, hardened steel and have smooth, black enamel finish.

The blade is 3/4" wide and 5/64" thick.
