Please Note
⚠ Candy: Due to the coloring process, Candy colors flow and are fairly random, so each piece may look different.
⚠ White lines on threads: Some screws may show white lines on the threads. This is a normal result of the coloring process, so you can use them with confidence.

Strong Yet Lightweight
S-PARTS works with metal raw material suppliers in Xi'an's civil aerospace industry to source Grade 5 Titanium (Ti-6Al-4V). Materials are carefully selected through rigorous, ongoing laboratory comparison testing to meet S-PARTS standards.
The material's average tensile strength exceeds 1,050 MPa, well above the industry minimum of 895 MPa. Under the same conditions, S-PARTS titanium fasteners deliver mechanical performance comparable to 10.9-grade steel at about half the weight, with an exceptional strength-to-weight ratio.
Precision Manufacturing
Screw heads are hot-forged in custom S-PARTS dies. To maintain precision during high-temperature operations at 650°C, each die is used no more than 300 times.
Fastener bodies are machined at S-PARTS' own factory on military-grade precision CNC machines, with micron-level tolerance control for precise thread engagement.
Color Finishes
PVD Vacuum Nitride Coating (Gold, Rainbow, Black, Blue, Copper): Forms a dense nitride metal layer on the part surface, improving surface hardness and impact resistance. The color reaches deep into the surface layer and resists fading under normal use, including rain and mud. Heavy abrasion can still wear it.
Anodizing (Green, Purple, Candy, Indigo): Electrolytic oxidation forms an oxide layer of varying thickness on the titanium surface, adding surface hardness and corrosion resistance. Because layer thickness affects how light refracts, incoming and reflected light interfere to create vivid color. No dye is used.
