- Versatile right-hand threading allows for standard installation in a broad range of metric-based industrial equipment
Professional Applications & Engineering Value
This M4 nylon socket head cap screw is engineered to address common challenges in electrical, automotive, and consumer goods assembly where corrosion resistance, electrical insulation, and weight reduction are critical. The nylon plastic material inherently resists chemicals and moisture, preventing galvanic corrosion when used with dissimilar metals. Its hex drive design and coarse metric thread enable high torque application without stripping, making it ideal for repetitive disassembly in maintenance-heavy environments. With a temperature range of -40° to 140°F, it maintains integrity in both freezing and moderately high-heat conditions, while the UL 94 V-2 rating ensures flame retardancy for enhanced safety in enclosures and electronic devices.
Specification Summary & Compliance
This screw features M4 x 0.7mm coarse threads with a Class 6g tolerance for consistent fit, and is fully threaded for maximum grip length. It complies with UL 94 V-2 for flammability, RoHS 3 (2015/863/EU) for hazardous substance restriction, and REACH (EC 1907/2006) for chemical safety, ensuring adherence to international environmental and safety standards in industrial fastening applications.
