About the Product
Magnetic caps (also known as cup magnets or pot magnets) use a steel cup to direct and concentrate the magnetic field, significantly increasing holding force on a small footprint. These assemblies are perfect for clamping fixtures, workholding jigs, signage mounts, and removable fastenings. The steel cup also provides mechanical protection and improves durability. Select the size and grade needed for your holding force requirement, and review mounting options such as countersunk holes, threaded studs, or through-bores for your design.
