S-91217A070 M3 x 8 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 reducing replacement frequency.
• Enhanced torque transmission and stripping resistance due to the 1.5 mm hex drive, allowing for secure installation with standard tools.
• Reliable and permanent component positioning provided by the cone point with 90° angle, which bites into surfaces to prevent loosening under vibration.
• Consistent and precise thread engagement ensured by the Class 6g thread fit, minimizing the risk of cross-threading and assembly errors.
• High mechanical strength and durability from Rockwell B80 hardness, maintaining fastener integrity under load and repeated use.
• Broad compatibility and easy sourcing with coarse M3 x 0.5 mm metric threading, conforming to widely adopted DIN 914 and ISO 4027 standards.
• Safe for use in regulated industries as it is fully compliant with RoHS 3 and REACH environmental directives.

Professional Applications & Engineering Value

This M3 set screw is engineered to address critical challenges in precision assembly, where vibration resistance and secure component alignment are paramount. The 18-8 stainless steel material offers excellent resistance to oxidation and chemical exposure, making it suitable for electrical enclosures, automotive subsystems, and industrial machinery. The headless design and cone point tip allow for flush mounting and deep engagement into shafts or hubs, effectively preventing axial movement. With its hex drive and Class 6g thread fit, it ensures quick, reliable installations without compromising thread integrity, reducing downtime and maintenance costs in high-demand applications.
