Magnetic Male Round Standoffs

Mount or reposition internally-threaded parts instantly—these magnetic-backed standoffs snap onto metal surfaces. Install on displays, test rigs, and tight spaces where permanent mounting isn't practical.

Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

Rubber-Coated Stainless Steel—Reduce corrosion and prevent slipping. These standoffs withstand exposure to saltwater and chemicals, but are not as strong as steel.

Alnico Magnet—Retain their magnetic strength, even when exposed to high temperatures.

Neodymium Magnet—Our strongest magnets. These support heavy connections, but have lower heat resistance than Alnico magnets.

Magnetic Female Round Standoffs

Threaded

Mount or reposition male-threaded parts instantly—these magnetic-backed standoffs snap onto metal surfaces. Install on displays, test rigs, and tight spaces where permanent mounting isn't practical.

Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

Brass—Resist corrosion in wet environments. Brass is softer and less likely to dent surfaces than steel. Don't mount brass standoffs directly to steel, or they'll create a short circuit that reduces magnetism up to 15%.

Alnico Magnet—Retain their magnetic strength, even when exposed to high temperatures.

Neodymium Magnet—Our strongest magnets. These support heavy connections, but have lower heat resistance than Alnico magnets.
