Spi 13-460-1 Combination Square Blade 24 in 16R

Product Description

The SPI 13-460-1 is a 24-inch replacement blade designed for use with combination squares in layout and measurement applications. Finished with a baked enamel coating for corrosion resistance and long-term legibility, this blade carries 16R graduation markings at 1/100, 1/64, 1/50, and 1/32 inch intervals. It is suited for machinists, toolmakers, pipefitters, and other trade professionals who require precise scribing, squaring, and depth measurement in fabrication or maintenance work. The blade weighs 1 pound and ships as a single unit.

This blade is used in precision layout work across metalworking, pipefitting, and general fabrication environments. Its 16R graduation series covers four common fractional and decimal scales on a single blade, reducing the need to switch tools during layout. It fits standard combination square heads and is appropriate for both shop and field use where accurate linear measurement is required.
