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.

Ceramic Adjustment Screwdrivers
Use these ceramic-tipped screwdrivers for adjusting sensitive electronic components such as capacitors and resistors. They're completely nonconductive and nonmagnetic so there's no risk of short-circuiting or creating magnetic interference. Press the rotating end cap on the handle with your palm to apply constant pressure while turning the body of the screwdriver with your fingertips. Ceramic is nonmarring and won’t scratch components, but it's also brittle so these tools are not recommended for final tightening of screws.

Ceramic Changeable-Shaft Adjustment Screwdriver Sets
Use these ceramic-tipped screwdrivers for adjusting sensitive electronic components such as capacitors and resistors. They're completely nonconductive and nonmagnetic so there's no risk of short-circuiting or creating magnetic interference. Set includes a handle and two reversible shafts. Remove and replace the shafts to use a different size or drive style. Ceramic is nonmarring and won't scratch components, but it's also brittle so these tools are not recommended for final tightening of screws.

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.
