S-93285A412 M6 x 6 mm ASME B18.3.6M Set Screws

Key Features & Benefits at a Glance

• Secure Component Positioning – Nylon 6/6 plastic tip prevents surface damage and maintains consistent clamping force without marring shafts or components.
• Corrosion-Resistant Durability – 18-8 stainless steel construction ensures long-term reliability in humid or chemically aggressive industrial environments.
• High-Temperature & Low-Temperature Performance – Nylon tip operates reliably from -50° to 250°F, maintaining sealing and vibration resistance across varied conditions.
• Precise Thread Engagement – Class 6g thread fit and M6 x 1 mm coarse pitch enable quick assembly with consistent torque transmission and reduced cross-threading risk.
• Space-Saving Headless Design – Flush installation with 3 mm hex drive allows use in confined spaces while providing ample torque application.
• Regulatory Compliance for Global Supply Chains – Meets ASME B18.3.6M dimensional standards and complies with RoHS 3 and REACH environmental directives.
• Enhanced Grip & Reusability – Rockwell B80 hardness balances strength with ductility, allowing repeated adjustments without thread deformation.

Professional Applications & Engineering Value

Engineered for precision fastening in dynamic assemblies, this M6 nylon tip set screw addresses common challenges in machinery, automation, and electronics. The 18-8 stainless steel body resists oxidation in demanding settings, while the green nylon 6/6 tip acts as a self-locking element that dampens vibration and prevents fretting on shafts, gears, and collars. Its headless hex drive design is ideal for applications where protruding hardware interferes with moving parts or requires a streamlined profile. With a coarse metric thread (1 mm pitch), installers achieve faster engagement and reduced assembly time, critical in high-volume production lines. The screw’s soft tip eliminates the need for separate non-marring pads, making it a cost-effective solution for protecting finished surfaces in precision equipment and adjustable mechanisms.

Specification Summary & Compliance
