Frequently Asked Questions
What is the primary purpose of gage block accessories?
Gage block accessories are designed to expand the usability of gage blocks. They enable the creation of more complex measuring setups, improve stability, and allow for tasks like marking and comparative measurements.
Are all gage block accessories interchangeable?
While many accessories share common designs, compatibility can vary. It's best to check specifications to ensure a proper fit with your specific gage blocks, especially for holders and clamps.
What materials are typically used for these accessories?
