Spi 13-262-1 Combination Square Set 6 in 3 Piece

Product Description

The SPI 13-262-1 is a 3-piece combination square set built for precision layout and inspection work in the field or on the bench. The set includes a 6-inch hardened steel blade and a cast iron center square head, delivering the rigidity and wear resistance required for repeated, accurate measurement. The blade features 4R graduation, providing four reading scales: 1/16, 1/32, 1/64, and 1/8 inch. At 2.9 pounds, the set is substantial enough to stay planted during use. Machinists, pipefitters, and fabricators rely on this type of tool for scribing, squaring, and centering tasks across a range of materials and surfaces.

This combination square set is suited for use in fabrication shops, mechanical rooms, and on job sites where accurate layout work is required. The 4R blade graduation makes it compatible with both coarse and fine measurement tasks. The cast iron head resists deformation under normal shop conditions, making the set a practical choice for tradespeople who need a dependable layout tool that holds calibration through regular use.
