FAQ

What torque specifications should I use for titanium flange nuts?

Torque specifications for titanium fasteners differ significantly from steel equivalents due to titanium's unique friction characteristics and elastic modulus. Calculate torque values based on 70-80% of the fastener's proof load, factoring in the specific lubricant or anti-seize compound used. Never apply steel torque specifications directly to titanium fasteners, as this can lead to over-tightening and thread damage.

How do I prevent galling when installing titanium flange nuts?

Galling prevention requires proper lubrication and installation technique. Apply high-quality anti-seize compounds containing molybdenum disulfide or specify fasteners with factory-applied DLC coatings. Install fasteners slowly with consistent pressure, avoiding rapid or jerky motions that can initiate cold welding between titanium surfaces.

Can titanium flange nuts replace stainless steel in existing applications?

Titanium fasteners can generally substitute for stainless steel components, often providing superior performance in corrosive environments. However, consider galvanic compatibility with mating materials and verify that thread specifications match existing hardware. The weight reduction and corrosion resistance typically justify the higher initial cost through extended service life and reduced maintenance requirements.

What quality certifications should I require from suppliers?
