S-93285A211 M4 x 5 mm ASME B18.3.6M Set Screws

Key Features & Benefits at a Glance

• Secure, Non-Marring Fastening: The green nylon 6/6 plastic tip prevents damage to shaft surfaces, ensuring a firm grip without scratching or galling.
• Excellent Corrosion Resistance: Manufactured from 18-8 Stainless Steel, this screw offers reliable performance in demanding environments, resisting rust and corrosion.
• High-Torque Assembly & Durability: The internal hex socket (2 mm drive) and Rockwell B80 hardness allow for high installation torque and excellent resistance to wear and deformation.
• Broad Temperature Compatibility: The nylon tip maintains its integrity across a wide temperature range from -50° to 250° F, ensuring consistent performance in varied operating conditions.
• Precise & Reliable Thread Engagement: Featuring a Class 6g thread fit and coarse M4 x 0.7mm thread, it ensures easy assembly and a secure hold with minimal risk of cross-threading.
• Streamlined, Space-Saving Design: The headless (set screw) profile allows for flush mounting in applications where protruding fastener heads are not feasible.
• Compliant with Major Standards: Meets ASME B18.3.6M for dimensional consistency and is RoHS 3 & REACH compliant, supporting your environmental and regulatory requirements.

Professional Applications & Engineering Value

This M4 nylon tip hex socket set screw is engineered to solve critical challenges in precision assembly and motion control systems. The 18-8 stainless steel construction provides the necessary strength and corrosion resistance for long-term reliability in industrial machinery, automotive components, and electronic enclosures. The nylon 6/6 plastic tip is specifically designed to exert clamping force without marring precision shafts, gears, or collars, making it ideal for applications requiring repeated adjustments or disassembly. Its coarse thread (0.7mm pitch) and Class 6g thread fit facilitate quick and accurate installation, reducing assembly time while preventing loosening under vibration. This combination of a durable metal body and a protective, temperature-resistant non-metallic tip delivers exceptional engineering value by protecting costly components and ensuring consistent clamping performance.
