Low-permeability, non-magnetic screws and couplings in titanium, phosphor bronze, ceramic and specific stainless grades for MRI, semiconductor and precision-measurement systems.
Overview
Where a stable magnetic field is critical (MRI and imaging, semiconductor e-beam and sensor systems, radar and precision instruments), components must have low magnetic permeability. For critical applications it is more reliable to specify a maximum allowable permeability (µr value) than to simply state "non-magnetic". NBK supplies non-magnetic screws and couplings in titanium, phosphor bronze, ceramic and specific austenitic stainless grades.
These materials also resist corrosion, which suits sterilisation and cleanroom use. Optional ultrasonic cleaning is available. Full specifications and CAD files are on nbk1560.com. Tell us your maximum permeability and load, and our engineers match the right non-magnetic component.
Titanium, phosphor bronze, ceramic and specific stainless grades.
Avoids interference with imaging, sensors and precision measurement.
Suited to sterilisation and cleanroom environments.
Vented (drilled) socket-head cap screws that release trapped air and gases during pump-down to prevent virtual leaks in vacuum and cleanroom systems.
Grade 2 and Grade 5 titanium socket-head cap and machine screws: lightweight, non-magnetic and chemically resistant for medical, aerospace and semiconductor use.
Low-permeability fasteners in titanium, SUS316L HiMo, tantalum, phosphor bronze and brass for MRI, cryogenic, semiconductor and precision magnetic instruments.
Fasteners for service far beyond 200 °C: SUS316L, molybdenum, ceramic, Vespel, Hastelloy and Inconel screws for furnaces, plasma and high-temperature process equipment.
Screws that protect the thread and head against aggressive chemicals: SUS316L HiMo, Inconel, Hastelloy C-276 and titanium for process, plating and semiconductor equipment.
High-strength fasteners in Grade 5 titanium, SUS316L, chrome-molybdenum steel, aluminium and RENY plastic that let designers downsize while keeping fastening strength.
For critical applications, specifying a maximum allowable magnetic permeability (µr value) is more reliable than simply stating "non-magnetic", because materials differ in how weakly magnetic they are. NBK can advise on the right material for your permeability target.
Titanium, phosphor bronze, ceramic and specific austenitic stainless grades (such as SUS316L HiMo) offer low magnetic permeability, suited to MRI, semiconductor and precision-measurement systems.
