Titanium Fastener Buying Guide

Titanium fasteners deliver high strength at low weight with outstanding corrosion resistance — popular in aerospace, marine and chemical assemblies.

Common Grades

• Grade 2 — corrosion service, lower strength
• Grade 5 (Ti-6Al-4V) — high-strength structural bolts
• Grade 7 — best corrosion in reducing acids

Strength & Weight

Grade 5 bolts rival many steel grades in strength while weighing ~40% less and never rusting.

Avoiding Galling

Titanium threads can gall. Use anti-seize lubricant, controlled tightening speed, and rolled (not cut) threads to reduce the risk.

Where They Shine

• Aerospace and motorsport (weight)
• Marine and offshore (seawater)
• Chemical plants (corrosion)
• Medical devices (biocompatibility)

Specify

• Standard (DIN/ISO/ASME)
• Grade and finish
• Thread form and length
