S-92098A144 M5 x 5 mm DIN 551, ISO 4766 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with Class 6g thread fit ensuring precise engagement and reliable, vibration-resistant fastening in demanding applications.
• Exceptional durability provided by alloy steel construction and a Rockwell B67 hardness, offering excellent resistance to wear and deformation.
• Simplified installation and removal using a standard slotted screwdriver, thanks to the slotted drive style on the headless design.
• Optimized for coarse thread applications with an M5 x 0.8mm pitch, enabling quicker assembly and reduced risk of cross-threading.
• Secure and flush mounting achieved with the flat tip, making it ideal for set screw applications where a protruding head is not permissible.
• Guaranteed material integrity and environmental compliance, being RoHS 3 and REACH compliant for use in regulated industries.
• Global interoperability assured by conformance to DIN 551 / ISO 4766 standards, ensuring consistent quality and dimensional accuracy.

Professional Applications & Engineering Value

This M5 set screw is engineered to address critical challenges in precision assembly and machinery. Its alloy steel composition and Rockwell B67 hardness provide the necessary strength to prevent loosening under dynamic loads and vibration, a common failure point in industrial equipment. The headless, slotted drive design allows for a flush finish, essential in applications with spatial constraints or rotating components where a protruding head could cause interference or safety hazards. The coarse thread with a 0.8mm pitch and Class 6g thread fit ensures rapid and secure installation into metric components, reducing assembly time while maintaining a tight, reliable grip. This makes it an indispensable component for securing collars, gears, and pulleys onto shafts in automotive, manufacturing, and automation systems, delivering long-term engineering value through its robust performance and standards compliance.

Specification Summary & Compliance
