Grid Fixture Plates
Use these plates as a foundation for your fixturing setups. Precision ground to tight tolerances, they have holes in a grid pattern for accurate, repeatable positioning.
Fixture plates are thinner and lighter in weight than subplates, so they're often used to build setups that are swapped in and out of machines. Steel plates are stronger than aluminum plates, and their threaded holes are tapped directly into the plate. Some also have unthreaded holes, which are jig-bored and lined with a precision bushing to help reduce wear and ensure accurate placement. Add chip plugs to keep chips and shavings from clogging or damaging unused holes.

Setup Blocks
Create setups with precise angles and accurate spacing for measuring, inspection, or machining. These blocks are precision ground to tight tolerances on all six faces, making them flat, square, and parallel. Made of hardened steel, they resist wear, so they’ll stay precise even with heavy use.
