Starrett Angle Gage Blocks
Starrett Angle Gage Blocks permit fast, simple and accurate measurements of any angle. They are far superior to sine bar measuring methods, that involve trigonometric formulae and complex stacks of gage blocks.
Starrett Angle gage blocks come in three accuracies: Croblox Reference Angle Blocks with a 1-second accuracy, Steel Calibration Grade Angle Blocks with 2-second accuracy, and Steel Working Grade Angle Blocks with 5-second accuracy. Each grade can also be purchased in sets that will measure in steps of one-second, one-minute or one-degree to suit any need.
Croblox Reference Angle Blocks: 1-second accuracy. Designed for optical or as reference standards for autocollimators, spectrometers, etc. They are for use in aerospace, optical, and other precision instrument fields.
Steel Calibration Angle Blocks: 2-second accuracy. The same high quality as the Reference Grade Angle Blocks, but are manufactured from hardened tool steel for better economy
Steel Working Angle Blocks: 5-second accuracy. These angles are designed for shop or tool room. The longer gaging surfaces are made for use with an indicator. These blocks reduce set-up time and minimize error in grinding both simple and compound angles.
