Starrett - Height Gages

These gages combine the accuracy of Starrett-Webber Gage Blocks with a precision micrometer head and digital readout.

Readability Features

• Satin chrome scales mounted beside the gage block column for quick reference to the nearest 1" or 25 mm reading
• Digital readout reads in .001" or 0.01 mm and has a range of 1" or 25 mm
• Reads directly from the micrometer head to .0001" or 0.002 mm. The micrometer head (our No. 469) has black figures on the satin chrome thimble. The graduations are staggered for easy counting
• Both the micrometer head and digital readout are mounted on top of the gage, directly in line with the operators' vision

Ease-of-Handling Feature

• The micrometer head has a speeder knob for rapid positioning
• Both over and under heights can be checked directly from the gage blocks in a single setting. Because reference surfaces are provided on the top and bottom of each block, adjacent blocks are in the exact same plane. This eliminates the need to add or subtract block thickness.
• Readings can also be taken from either left, center, or right of the gage block column
• Parts can be checked from .100" or 2 mm in height
• The gage block column design permits wringing a 1" block between two blocks in the column. This is convenient for setting and checking other gages such as inside micrometers, end measuring rods, dial bore gages, etc.

Accuracy and Long-Life Features

• Gage is housed in a heavily flanged frame for stability and the base has three-point hardened, ground, and lapped bearing pads, making it virtually tip-proof
• Gage blocks are assembled in a free-standing system that allows the blocks to conform to temperature variations independently of the frame, thereby reading the same as the work piece
• The highly accurate micrometer spindle is one piece, with the measuring threads ground from the solid, hardened, and stabilized
• A 10" riser block is available for increased height capacity
