Fasteners


Nickel, titanium, and stainless steel alloys are used for fasteners in space applications due to their strength, fatigue resistance, and ability to endure temperature fluctuations.

Ti-6AL-4V: This grade is typically used for bolts, screws, nuts, washers, and studs.

Ti-6AL-4V ELI: This ELI grade (extra-low interstitials) gives this grade enhanced toughness and ductility, making it an excellent option for engine fasteners and aircraft bolts.

625: Used for aerospace bolts, nuts, and screws 

718: Used in engine fasteners, turbine bolts, and high-temperature structural joints. 

A286: A popular choice for high-strength bolts, brackets, and structural fasteners. 

15-5 PH: Increased toughness and corrosion resistance make this alloy a great choice for fasteners, valves, gears, and pumps.
