S-91210A827 M6 x 30 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc plating that protects against rust and extends service life in demanding environments
• Exceptional holding power thanks to the 90° cone point design that digs securely into mating surfaces to prevent component slippage
• High-strength durability from alloy steel construction and Rockwell C45 hardness, ensuring reliable performance under vibration and load
• Effortless installation and removal with the 3 mm hex drive, providing a secure tool grip and reducing assembly time
• Precise thread engagement with Class 5g6g thread fit and M6x1 mm coarse thread, enabling quick assembly and consistent clamping force
• Versatile headless design that sits flush in applications where space is limited or a smooth surface profile is required
• Global compliance assurance meeting DIN 914/ISO 4027 standards for dimensional accuracy and material quality

Professional Applications & Engineering Value

This M6 set screw is engineered to solve critical fastening challenges in industrial machinery, automotive assemblies, and precision equipment. The zinc-plated alloy steel construction provides excellent corrosion resistance, reducing maintenance needs in humid or outdoor settings. Its headless design and cone point deliver maximum gripping force to secure gears, pulleys, and collars against shafts, preventing axial movement under high torque or vibration. The metric coarse thread (M6x1 mm) ensures rapid installation and robust thread engagement, while the hex drive allows for high tightening torque without stripping. Ideal for applications requiring flush mounting and reliable, long-term fastening without loosening.

Specification Summary & Compliance

This set screw maintains Class 5g6g thread tolerance per ISO metric standards, ensuring precise fit and consistent performance. It is manufactured to comply with DIN 914 and ISO 4027 specifications for dimensional accuracy, material properties, and mechanical requirements. The product is fully RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, meeting environmental and safety regulations for hazardous substances. The Rockwell C45 hardness and specified cone point angle (90°) are verified to deliver the declared engineering performance and durability.
