(3) D16 High-precision Hole System
Hole diameter is 16mm, and the hole pitch is usually 50mm or 100mm (standard grid).
The hole is internally threaded with M16, compatible with various D16 standard fixtures (locating pins, clamps, etc.).
(4) Super Durability
Nitriding treatment (surface hardness can reach HV800 - 1000), wear-resistant and resistant to welding slag spatter.
Rust and corrosion prevention, suitable for humid or high-welding fume environments.

Maintenance and Care
Regular Cleaning: Use a wire brush or compressed air to remove welding slag to prevent blockage of the hole system.
Rust Prevention Treatment: Apply rust-proof oil when not in use for a long time, especially for the protection of the nitrided layer.
Avoid Overloading: For heavy workpieces, the load should be evenly distributed to prevent deformation of the tabletop.
Fixture Maintenance: Check whether the threads of the fixture are in good condition to avoid thread stripping affecting accuracy.
