S-94085A093 M3 x 6 mm ASME B18.3.6M, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Secure, damage-free fastening with a soft brass tip that prevents marring of mating surfaces while maintaining excellent grip
• Superior corrosion resistance and durability from the black-oxide finish on the alloy steel body, extending service life in demanding environments
• High-strength performance backed by a Rockwell C28 hardness rating, ensuring the screw withstands high vibrational and torsional loads
• Precise and reliable thread engagement with a Class 5g6g thread fit, providing consistent clamping force and reducing the risk of loosening
• Easy installation in confined spaces thanks to the headless design and 1.5 mm hex drive, allowing for flush mounting and tool accessibility
• Optimized for high-volume assembly with a coarse M3 x 0.5 mm thread pitch, enabling faster driving and reduced cross-threading risk
• Broad industrial compliance meeting ASME B18.3.6M, RoHS 3, and REACH standards for global quality and environmental safety

Professional Applications & Engineering Value

This M3 set screw is engineered to solve critical challenges in precision assembly and machinery. The black-oxide alloy steel construction provides a robust base that resists rust and wear, ideal for automotive, aerospace, and electronic enclosures where environmental factors are a concern. The brass soft tip is a key differentiator, offering a non-marring contact point that protects sensitive shafts or gears from damage during clamping, eliminating the need for additional components. Combined with the Class 5g6g thread fit and coarse pitch, it ensures rapid, secure installation with high repeatability, reducing assembly time and maintenance costs. Its headless design and hex drive make it perfect for applications requiring a low-profile fastener that can be tightened in tight spaces, delivering reliable holding power without compromising the assembly's aesthetics or function.
