S-94095A110 M4 x 4 mm ASME B18.3.6M, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Vibration-resistant locking with a soft green nylon 6/6 tip that prevents loosening under dynamic loads and temperature fluctuations from -50° to 250°F.
• Superior corrosion protection from the black-oxide finish on alloy steel, extending service life in harsh industrial environments.
• Precise thread engagement with Class 5g6g fit and coarse M4 x 0.7mm threads for reliable fastening and easy installation in high-volume applications.
• High-strength durability backed by Rockwell C28 hardness, ensuring the set screw maintains integrity under repeated torque and stress.
• Space-saving headless design with a 2 mm hex drive, allowing flush mounting in confined assemblies without protruding components.
• Broad regulatory compliance meeting ASME B18.3.6M, RoHS 3, and REACH standards for safe, global use in regulated industries.
• Secure tamper-resistant installation due to the hex drive and right-hand thread, providing controlled tightening for critical mechanical joints.

Professional Applications & Engineering Value

This M4 set screw with a black-oxide alloy steel body and nylon tip addresses common industrial challenges like part slippage and corrosion in machinery. The Class 5g6g thread fit and coarse thread spacing ensure rapid, precise assembly in automated systems, reducing downtime. Its headless hex drive design is ideal for compact spaces in motor mounts, conveyor systems, and precision instruments, where flush surfaces are critical. The nylon 6/6 plastic tip absorbs vibrations and resists temperatures from -50° to 250°F, preventing unintended loosening in dynamic applications like robotics or automotive assemblies. Engineered to ASME B18.3.6M specifications, it delivers consistent performance for OEMs and maintenance teams seeking reliable, compliant fasteners.

Specification Summary & Compliance

This metric set screw features an M4 x 0.7mm thread with Class 5g6g tolerance for precise fit, coarse thread spacing, and a length of 4 mm. It complies with ASME B18.3.6M manufacturing standards and is verified to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safety and sustainability in industrial use.
