- Slotted drive and flat tip facilitate straightforward installation using standard tools.
Professional Applications & Engineering Value
Engineered for precision, these M0.9 metric screws with a fully threaded design and 18-8 stainless steel material excel in applications where space is limited and corrosion resistance is critical. The narrow cheese head (1.4 mm diameter) and coarse thread pitch of 0.225 mm enable secure fastening in compact electronics, medical devices, and aerospace components, reducing the risk of loosening under vibration. The passivated finish enhances durability against moisture and chemicals, while the 70,000 psi tensile strength ensures reliable performance in high-stress environments. Ideal for industrial screws requiring strict compliance, they solve common issues of part failure and assembly inefficiency.
Specification Summary & Compliance
This screw features a metric thread size M0.9 with a coarse pitch of 0.225 mm and right-hand thread direction, designed for general use without a rated thread fit. It meets NAS721CE90-080 specifications for precision and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity.
