S-94095A127 M6 x 8 mm ASME B18.3.6M, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Secure, Non-Marring Fastening: The green nylon 6/6 tip prevents damage to shaft surfaces and provides excellent vibration resistance, ensuring a reliable, long-term hold.
• Superior Corrosion Resistance: The black-oxide finish on the alloy steel body offers enhanced protection against rust and oxidation in demanding industrial environments.
• High-Strength Construction: Made from alloy steel with a Rockwell C28 hardness, this screw delivers exceptional shear and tensile strength for heavy-duty applications.
• Precise, Reliable Thread Engagement: Metric coarse threads with a Class 5g6g fit ensure easy installation and consistent, accurate seating in tapped holes.
• Wide Operational Temperature Range: The nylon tip performs reliably in temperatures from -50° to 250° F, maintaining its locking properties in varied conditions.
• Optimized for Tight Spaces: The headless, hex drive design allows for installation in confined areas where clearance is limited, using a standard 3 mm hex key.
• Guaranteed Quality & Safety: Compliant with ASME B18.3.6M, RoHS 3, and REACH standards, ensuring material safety and consistent manufacturing quality.

Professional Applications & Engineering Value

This M6 set screw is engineered to solve critical challenges in assembly and motion control systems. The black-oxide alloy steel construction provides the necessary high-strength and corrosion resistance for permanent fastening in machinery, automotive components, and electrical enclosures. Its headless design and hex drive are ideal for applications with minimal clearance, such as securing collars, gears, and pulleys onto shafts. The nylon tip is a key feature, acting as a self-locking element that prevents loosening from vibration—a common failure point in dynamic systems—while protecting the shaft from scoring. This combination of durable materials and intelligent design delivers reliable performance, reduces maintenance needs, and extends the service life of the assembled product.
