S-93640A147 M4 x 16 mm UL 94 V-2 Plastic Socket Head Screws

Key Features & Benefits at a Glance

• Excellent corrosion resistance and electrical insulation properties due to the durable Nylon Plastic material, ideal for sensitive electronic and marine environments.
• Secure and reliable fastening with a Class 6g thread fit, ensuring consistent performance and ease of assembly in metric applications.
• Wide operational temperature tolerance from -40° to 140° F, making it suitable for both freezing and moderately high-temperature industrial settings.
• High-strength hex drive (9/64") provides superior torque transmission and reduces the risk of tool slippage or head stripping during installation.
• Fully threaded M4 x 0.7 mm coarse thread design offers maximum grip and holding power for a wide range of material thicknesses.
• Compliance with major safety and environmental standards including UL 94 V-2 flammability rating, RoHS 3, and REACH, ensuring product safety and regulatory acceptance.
• Compact, low-profile socket head with a 6.7 mm diameter allows for use in confined spaces where clearance is limited.

Professional Applications & Engineering Value

This M4 metric socket head cap screw is engineered from robust Nylon Plastic to address common industrial challenges such as galvanic corrosion, electrical conductivity, and weight reduction. The coarse thread (0.7 mm pitch) and Class 6g thread fit ensure quick, reliable installation and vibration resistance in dynamic assemblies. Its hex drive and fully threaded design provide consistent clamping force, making it ideal for securing components in electrical enclosures, automotive panels, and consumer appliances. The material's inherent properties eliminate the need for additional insulating washers, streamlining the B2B procurement process for non-metallic fasteners that meet stringent UL 94 V-2 and RoHS standards.

Specification Summary & Compliance

This screw adheres to metric system dimensions with an M4 thread size, 0.7 mm pitch coarse thread, and a length of 16 mm. The thread fit is Class 6g per ISO standards, ensuring dimensional accuracy and interchangeability. It is manufactured to comply with UL 94 V-2 for flammability safety, RoHS 3 (2015/863/EU) for hazardous substance restriction, and REACH (EC 1907/2006) for chemical management, confirming its suitability for global industrial and commercial applications.
