S-91210A721 M6 x 40 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with a 90° cone point that bites into mating surfaces, preventing component slippage under vibration.
• Exceptional durability and wear resistance provided by the high-strength alloy steel and Rockwell C45 hardness.
• Secure and flush installation due to the headless design, ideal for confined spaces where protrusions are not permissible.
• Effortless installation and high torque transmission enabled by the internal 3 mm hex drive.
• Reliable and precise coarse thread engagement with a Class 5g6g thread fit, ensuring consistent clamping force.
• Guaranteed material safety and environmental compliance by meeting RoHS 3 and REACH regulations.
• Broad industry acceptance and interchangeability through conformity with DIN 914 and ISO 4027 standards.

Professional Applications & Engineering Value

This M6 set screw is engineered to solve critical challenges in industrial assembly and machinery. The alloy steel construction and Rockwell C45 hardness provide the necessary strength to resist shear forces and maintain clamp load in high-vibration environments. The headless design and 90° cone point are specifically valuable for securing gears, pulleys, and collars on shafts, creating a positive lock that prevents axial movement without requiring a protruding head. The coarse metric thread and Class 5g6g thread fit allow for quick assembly and reliable performance, making it a trusted component for demanding applications in automotive, manufacturing, and heavy equipment.

Specification Summary & Compliance
