S-99642A127 M6 x 20 mm DIN 916, ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with the cup point design that bites into mating surfaces, preventing loosening under vibration.
• Enhanced durability and wear resistance provided by the Alloy Steel construction and Rockwell C45 hardness.
• Precise and reliable fastening ensured by the Class 5g6g thread fit and fine 0.75mm pitch for accurate engagement.
• Easy and secure installation with the internal hex drive (3mm) and headless design, ideal for confined spaces.
• Guaranteed quality and interchangeability through compliance with DIN 916 and ISO 4029 international standards.
• Safe for use in regulated industries as it is fully RoHS 3 and REACH compliant.
• Versatile for demanding applications due to its right-hand metric thread and robust material properties.

Professional Applications & Engineering Value

This M6 set screw is engineered to solve critical challenges in industrial assembly, such as component slippage and fastener failure under stress. The alloy steel material, hardened to Rockwell C45, provides exceptional shear and tensile strength, making it suitable for high-load scenarios in machinery, automotive, and precision equipment. The cup point creates a permanent indentation, offering superior resistance to rotational forces and vibration—a common pain point in dynamic environments. Its fine thread with a 0.75mm pitch and Class 5g6g fit ensures tight tolerances and reliable performance in precision set screw applications, reducing the need for frequent maintenance and replacements.
