Professional Applications & Engineering Value
This M4 left-hand metric screw with coarse 0.7mm pitch and 18-8 stainless steel construction addresses critical needs in reverse-thread mechanisms, such as counter-rotating equipment, safety-critical assemblies, and maintenance-prone systems where standard right-hand threads may loosen under vibration. The button head hex design provides a sleek, low-profile solution that minimizes protrusion in compact spaces, while the Rockwell B85 hardness and 80,000 PSI tensile strength ensure durability against shear and fatigue. Commonly used in industrial machinery, automotive components, and electronic enclosures, this fastener delivers reliable performance in corrosion-resistant applications, reducing downtime and replacement costs.
Specification Summary & Compliance
Manufactured to precise metric standards with M4 x 0.7mm coarse threads and Class 6g thread fit for consistent dimensional accuracy. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety requirements. The screw features a 16mm length, fully threaded design, and meets industry specifications for left-hand threading applications.
