Ceramic Hex Head Screws
Ceramic screws won't melt, rust, seize, or become brittle—even at extreme temperatures. They are nonconductive and highly resistant to corrosive gases. Length is measured from under the head. To ensure compatibility, use these screws with ceramic nuts.

Encased Ceramic Magnets with Threaded Stud
A steel case concentrates and focuses the magnetic field. It also protects the magnetic material.
Warning: Maximum pull ratings are based on direct contact with rust-free and unpainted iron plate. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.
