The Anti-fatigue cylindrical head hexagonal slot M1.6 SUS410 hydraulic valve body high pressure fastener is a
Mini screw developed for extreme working conditions. The whole is made of hardened SUS410 stainless steel with a tensile strength of ≥1100 MPa. The combination of cylindrical head and hexagonal slot can still withstand a pulse pressure of up to 70 MPa in a narrow valve body to achieve reliable locking. The M1.6 fine thread remains sealed in high-pressure oil to avoid micro-motion wear, and is an indispensable high-pressure micro screw for hydraulic systems.
As a high-precision screw, its thread accuracy reaches 6 g, the head coaxiality is ≤0.02 mm, and with pre-coated microcapsule anaerobic glue, the assembly torque attenuation is <5% after 10⁶ fatigue cycle tests. The surface is subjected to low-temperature ion nitriding + mirror polishing, which not only improves the surface hardness but also reduces the friction coefficient, ensuring that it will not loosen in a long-term vibration environment.
In key locations such as aviation hydraulic modules and satellite propulsion systems, this fastener complies with the ASTM F837 standard and can be used as a direct replacement for titanium alloy parts for
Aerospace Micro Screws. It reduces weight by 35% while being temperature resistant from −55°C to +200°C, providing the ultimate connection solution for high-end equipment that is lightweight, long-life, and leak-free.
