Professional Applications & Engineering Value
This M4 x 0.7 mm metric screw is engineered for precision assemblies where reliability and corrosion resistance are critical. The 18-8 Stainless Steel construction, combined with a passivated finish, effectively resists oxidation and chemical exposure, making it suitable for automotive, electronics, and outdoor equipment. The T20 Torx drive prevents stripping under high torque, reducing downtime in automated production lines. With a rounded button head and coarse thread, it offers quick installation and secure fastening in metals and plastics, addressing common issues like thread galling and misalignment. Fully compliant with ISO 7380, it ensures dimensional accuracy and interchangeability in global engineering projects.
Specification Summary & Compliance
This screw adheres to ISO 7380 standards, with precise Class 6g thread fit and metric coarse threading (0.7 mm pitch). It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety. The fully threaded design and right-hand thread direction support efficient assembly, while the 100,000 psi tensile strength underscores its durability for industrial use.
