Checking Squareness with DIN 875 Machinist Squares

Machinist squares, also called engineer's try squares, are the basic tool for verifying squareness on machined components, checking setups on machine tools, and laying out work. We supply precision squares from Insize and Starrett manufactured to DIN 875 in grades 00 and 0 for inspection and toolroom applications.

Each square has a hardened and ground blade set at an exact 90 degrees to a stable stock. Grade 00 squares are reserved for inspection and calibration work, while grade 0 is the standard for general machine shop use. Available sizes from 50mm to 300mm cover component inspection and machine setup needs.

To keep inspection standards traceable, pair machinist squares with Gauge Blocks and Angle Gauges for comprehensive dimensional and geometric verification in your QC bay.
