Professional Applications & Engineering Value
These M4 metric spanner screws with 18-8 stainless steel construction and passivated finish address critical challenges in industrial assembly where corrosion resistance and mechanical reliability are paramount. The Class 6g thread tolerance and coarse thread pitch provide excellent vibration resistance in machinery, electrical enclosures, and automotive components, preventing loosening under dynamic loads. The drilled spanner drive enables precise torque application in confined spaces where socket access is limited. With fully threaded design and rounded pan head profile, these fasteners deliver consistent clamping force while maintaining a low-profile appearance for applications requiring both structural integrity and aesthetic considerations.
Specification Summary & Compliance
Manufactured to precise metric thread standards with Class 6g thread fit tolerance for consistent performance. The M4 x 0.7mm coarse thread configuration ensures proper engagement in various materials. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and restricted substance adherence. Mechanical properties include 80,000 psi tensile strength and Rockwell B85 hardness for reliable performance in industrial fastening applications.
