Information about Gage Blocks

Gage blocks are manufactured to precise gage-maker tolerance grades for calibrating, checking, and setting fixed and comparative gages. Rectangular, square, wear, scribing and angle gage blocks are available in hardened steel, carbide and ceramic materials. Tolerance grades range from Lab Master or Grade 0.5 (AAA) blocks with +/- 1 micro-inches tolerances for standards laboratories to the lower inspection or working Grade 3 (A) blocks for gaging, setting and general inspection operations in production or tool room areas. Other proprietary blocks may be available for specific applications with higher or lower tolerances and configurations.

Products & Services Related to Gage Blocks

Air Gages

Air gages use pneumatic pressure and flow to measure or sort dimensional attributes.

Dimensional Gages and Instruments

Dimensional gages and instruments provide quantitative measurements of product or component dimensional and form attributes such as wall thickness, depth, height, length, inner diameter (ID), outer diameter (OD), taper or bore.

Laser Micrometers

Laser micrometers measure extremely small distances using laser technology.

Masters and Setting Gages

Masters and setting gages provide dimensional standards for calibrating other gages.

Plug and Pin Gages

Plug and pin gauges are used to compare hole and slot dimensions or locations to specific tolerances. This product area includes go gauges and no-go gauges.

Ring Gages

Ring gages are used for go / no-go assessment compared to the specified dimensional tolerances or attributes of pins, shafts, or threaded studs.

Thread Gages

Thread gages are dimensional instruments for measuring and/or verifying thread size, pitch or other parameters.
