Professional Applications & Engineering Value
These Class 10.9 metric rounded head screws deliver critical reliability in precision assemblies where space constraints and vibration resistance are paramount. The zinc-plated alloy steel construction provides essential corrosion protection for industrial equipment, electronic enclosures, and automotive components exposed to harsh environments. Engineered with fully threaded M2 coarse pitch design and hex drive configuration, these fasteners enable rapid installation in high-volume production while maintaining consistent clamping force. The button head style offers a streamlined profile for applications requiring flush mounting without compromising the 140,000 psi tensile strength. Ideal for securing sensitive components in robotics, instrumentation, and machinery where vibration resistance and repeated load cycles demand fastener integrity.
Specification Summary & Compliance
Manufactured to ISO 7380 standards with Class 6g thread fit tolerance for precision engagement. The M2 x 0.4 mm coarse thread configuration ensures optimal performance in most materials. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Mechanical properties include Class 10.9 strength rating, Rockwell C32 hardness, and 140,000 psi tensile strength.
