Intrinsic Devices specializes in the manufacture of nickel-titanium shape memory alloy products used for fastening, sealing and electrical interconnection.   We produce a family of standard heat shrinkable metal rings under the name UniLok.  Other products include tensioning rods, expanding rings, and expanding plugs and pins.

Our products incorporate sophisticated materials science in order to deliver ease of use, exceptional performance and the ultimate in reliability.  Intrinsic's fasteners are self-installing, building controlled preload forces which are independent of component tolerances and operator-to-operator variation.  Just position the part and heat it above the specified temperature.  As long as the mating components meet dimensional requirements, repeatable performance is assured.

We serve commercial and military OEM's worldwide with quality products delivered on time.  Applications include sensors, downhole tools, aerospace systems, process equipment, munitions, marine hardware and medical devices.
