Grade 2 titanium fastener kit, 1/4-20

Name: Grade 2 titanium fastener kit, 1/4-20
Brand: Argon
SKU: QF-1420

For assembling baskets, racks, and brackets in corrosive lines, where steel and stainless hardware rust or set up galvanic attack. Chosen for corrosion resistance and easy service.

Not for aerospace, medical, or high-load safety-critical joints. Grade 5 (Ti-6Al-4V) is a different product and never a silent substitute.
