S-93285A538 M8 x 12 mm ASME B18.3.6M Set Screws

Key Features & Benefits at a Glance

• Vibration-Resistant Locking: Nylon 6/6 plastic tip securely grips mating surfaces, preventing loosening from shock and vibration in dynamic applications.
• Superior Corrosion Resistance: Manufactured from 18-8 Stainless Steel for excellent durability and long-term performance in harsh or humid environments.
• High-Strength Fastening: A Rockwell B80 hardness rating ensures the screw maintains its form and clamping force under significant mechanical stress.
• Precise & Reliable Engagement: Class 6g thread fit provides consistent, accurate installation and a secure hold in tapped holes.
• Wide Thermal Tolerance: The nylon tip performs reliably across a broad temperature range from -50° to 250° F, ensuring stability in varied operating conditions.
• Easy Installation & Removal: The internal 4 mm hex socket drive allows for high-torque application with standard tools, simplifying maintenance.
• Component Protection: The non-marring nylon tip prevents damage to shafts and delicate components, preserving the integrity of your assemblies.

Professional Applications & Engineering Value

This M8 x 1.25mm nylon tip set screw is engineered to solve critical challenges in assembly and machinery. The headless design and coarse thread pitch make it ideal for applications where space is limited and rapid installation is required, such as securing collars, gears, and pulleys onto shafts. The green nylon 6/6 tip is a key engineering feature, providing a vibration-resistant lock that eliminates the need for separate lock washers or thread-locking compounds. This not only streamlines the bill of materials but also enhances reliability in industrial applications subject to constant motion and stress. Constructed from corrosion-resistant 18-8 Stainless Steel, it delivers long-term performance, reducing maintenance frequency and downtime in demanding environments.

Specification Summary & Compliance

This metric set screw conforms to the dimensional and mechanical requirements of ASME B18.3.6M. The M8 thread with a 1.25 mm pitch and Class 6g tolerance ensures precision fit and interchangeability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of hazardous substances and safe for use in various global markets.
