Titanium & Titanium Alloy Fasteners

The titanium & titanium alloy fasteners include titanium bolts, screws & studs manufactured to ASTM F468 / F468M and titanium nuts manufactured to ASTM F467 / F467M. Both of the standards cover 8 grades of titanium & titanium alloys: titanium Grade 1 (R50250), Grade 2 (R50400), Grade 4 (R50700), Grade 5 (R56400), Grade 7 (R52400), Grade 19 (R58640, Ti-38-6-44), Grade 23 (R56401, Ti-6Al-4V ELI), Grade 32 (R55111, Ti-5-1-1-1). The fasteners can be cold formed, hot formed, or machined from suitable material.
