Product Overview
Titanium Grade 1 nuts are precision fasteners manufactured from commercially pure titanium conforming to ASTM B348 and ASTM F67 standards. As the softest and most ductile of all titanium grades, Grade 1 offers exceptional corrosion resistance, outstanding formability, and a high strength-to-weight ratio. These nuts are non-magnetic, biocompatible, and ideal for applications where maximum corrosion resistance is required in low to moderate strength assemblies.
Titanium Grade 1 nuts are widely specified for use in chemical processing, desalination, marine, and medical equipment due to their ability to withstand aggressive environments, including chlorides and oxidizing acids, without suffering from crevice or pitting corrosion. All nuts are supplied with full traceability and EN 10204 3.1 certification.
