S-91217A160 M5 x 6 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
• Secure, vibration-resistant fastening thanks to the 90° cone point that bites into materials, preventing loosening under stress.
• High mechanical strength and durability provided by Rockwell B80 hardness, ensuring the screw withstands high torque and repeated use.
• Precise, reliable coarse threading (M5x0.8mm, Class 6g fit) for quick installation and robust holding power in a wide range of materials.
• Flush, space-saving design with a headless and hex socket drive, allowing for unobtrusive fastening in tight or recessed applications.
• Guaranteed dimensional accuracy and interchangeability through compliance with DIN 914 and ISO 4027 standards.
• Environmentally safe and regulated substance compliance meeting RoHS 3 and REACH, ensuring suitability for global industrial supply chains.

Professional Applications & Engineering Value

This M5 set screw is engineered to address critical challenges in precision assembly and machinery. Manufactured from 18-8 stainless steel, it offers excellent resistance to rust and corrosion, making it a reliable choice for applications exposed to moisture, chemicals, or outdoor conditions. The headless design and hex socket drive allow for a flush finish, which is essential in rotating components like pulleys, gears, and collars where protrusions can cause interference or safety hazards. The 90° cone point provides a sharp, concentrated biting action that securely locks the screw into place, effectively resisting vibrational loosening in dynamic systems. With its coarse metric thread (0.8mm pitch) and Class 6g thread fit, it ensures quick and secure engagement, reducing assembly time while maintaining high clamp force. Ideal for use in automotive, manufacturing, and electronic enclosures, this screw delivers consistent performance and longevity in demanding industrial applications.
