S-94085A100 M4 x 4 mm ASME B18.3.6M, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with black-oxide coating on alloy steel, extending service life in harsh industrial environments.
• Secure, non-marring fastening thanks to the soft brass tip that prevents damage to sensitive surfaces while maintaining strong holding power.
• High-strength performance with Rockwell C28 hardness, ensuring reliable load-bearing capacity and resistance to deformation under stress.
• Precise, coarse thread engagement with Class 5g6g fit for quick installation and reduced risk of cross-threading in high-vibration applications.
• Compact, space-saving design as a headless set screw, ideal for confined assemblies where protruding fasteners are not feasible.
• Easy installation and removal using a standard 2 mm hex key, providing efficient maintenance and reducing assembly time.
• Compliance with international standards including ASME B18.3.6M, RoHS 3, and REACH, ensuring safety and regulatory acceptance in global markets.

Professional Applications & Engineering Value

This M4 set screw is engineered to address common challenges in precision machinery and industrial equipment, where vibration resistance and surface protection are critical. The black-oxide alloy steel construction offers superior durability against wear and environmental exposure, while the soft brass tip eliminates galling and surface damage on shafts or gears, preserving component integrity. With a coarse metric thread and Class 5g6g tolerance, it ensures rapid, secure fastening in high-stress assemblies like motor mounts, couplings, and automation systems. The headless, hex drive design allows for flush mounting in tight spaces, making it an ideal choice for OEMs and maintenance teams seeking reliable, long-lasting fastening solutions.
